Delivery and transportation
Delivery arrangements
Delivery within the United States or Canada is by air-ride truck with custom-designed shipping material, crate, and pallet. International delivery normally involves air freight.
Unless otherwise instructed, the EMC Traffic Department arranges for delivery directly to the customer’s computer room. To ensure successful delivery of the system, EMC has formed partnerships with specially selected moving companies.
These companies have moving professionals trained in the proper handling of large, sensitive equipment. These companies provide the appropriate personnel, floor layments, and any ancillary moving equipment required to facilitate delivery. Moving companies should check general guidelines, weights, and dimensions.
NOTICE
Inform EMC of any labor union-based restrictions or security clearance requirements prior to delivery.
Pre-delivery considerations
Take into account the following considerations prior to the delivery at your site: l l l l
Weight capacities of the loading dock, tailgate, and service elevator if delivery is to a floor other than the receiving floor.
Length and thickness of covering required for floor protection.
Equipment ramp availability if the receiving floor is not level with computer room floor.
Set up the necessary network and gateway access to accommodate EMC Secure
Remote Support (ESRS) so that it will be available and operable for the installation date.
Moving up and down inclines
To prevent tipping when moving up and down inclines, the following guidelines are recommended: l l
When moving cabinets, all doors/drawers should be closed.
When moving the cabinet down an incline, the front of the cabinet must go first.
l
When moving the cabinet up an incline, the rear of the bay goes last.
All portions of the bay will clear ramp and threshold slopes up to 1:10 (rise to run ratio), per Code of Federal Regulations — ADA Standards for Accessible Design, 28
CFR Part 36.

Radio frequency interference
Electro-magnetic fields, which include radio frequencies can interfere with the operation of electronic equipment. EMC Corporation products have been certified to withstand radio frequency interference (RFI) in accordance with standard
EN61000-4-3. In Data Centers that employ intentional radiators, such as cell phone repeaters, the maximum ambient RF field strength should not exceed 3 Volts /meter.
The field measurements should be taken at multiple points in close proximity to EMC
Corporation equipment. It is recommended to consult with an expert prior to installing any emitting device in the Data Center. In addition, it may be necessary to contract an environmental consultant to perform the evaluation of RFI field strength and address the mitigation efforts if high levels of RFI are suspected.
The ambient RFI field strength is inversely proportional to the distance and power level of the emitting device.
Recommended minimum distance from RF emitting device
The following table provides the recommended minimum distances between EMC arrays and RFI emitting equipment. Use these guidelines to verify that cell phone repeaters or other intentional radiator devices are at a safe distance from the EMC
Corporation equipment.

Adaptive cooling
The systems apply adaptive cooling based on customer environments to save energy.
Engines and DAEs access thermal data through components located within their enclosures. Based on ambient temperature and internal activity, they set the cooling fan speeds. As the inlet temperatures increase, the adaptive cooling increases the fan speeds, with the resulting platform power increasing up to the maximum values shown below. These values, along with the SPS recharge power consumption, contribute to the maximum system power consumption values over 35°C shown in

Airflow
Specifications
Systems are designed for typical hot aisle/cold aisle data center cooling environments and installation: l l
On raised or nonraised floors.
In hot aisle/cold aisle arrangements.
The airflow provides less mixing of hot and cold air, which can result in a higher return temperature to the computer room air conditioner (CRAC). This promotes better heat transfer outside the building and achieves higher energy efficiency and lower Power
Usage Effectiveness (PUE). Additional efficiency can be achieved by sequestering the exhaust air completely and connecting ducts directly to a CRAC unit or to the outside.
Best practice is to place a perforated floor tile in front of each bay to allow adequate cooling air supply when installing on a raised floor. The following figure shows typical airflow in a hot aisle/ cold aisle environment.

Air quality requirements
VMAX All Flash arrays are designed to be consistent with the requirements of the
American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE)
Environmental Standard Handbook and the most current revision of Thermal
Guidelines for Data Processing Environments, ASHRAE TC 9.9 2011.
The arrays are best suited for Class 1A Datacom environments, which consist of tightly controlled environmental parameters, including temperature, dew point, relative humidity and air quality. These facilities house mission critical equipment and are typically fault tolerant, including the air conditioners. In a data center environment, if the air conditioning fails and the temperature is lost, a vault may occur to protect data.
The data center should maintain a cleanliness level as identified in ISO 14664-1, class 8 for particulate dust and pollution control. The air entering the data center should be filtered with a MERV 11 filter or better. The air within the data center should be continuously filtered with a MERV 8 or better filtration system. In addition, efforts should be maintained to prevent conductive particles, such as zinc whiskers, from entering the facility.
The allowable relative humidity level is 20–80% non condensing, however, the recommended operating environment range is 40–55%. For data centers with gaseous contamination, such as high sulfur content, lower temperatures and humidity are recommended to minimize the risk of hardware corrosion and degradation. In general, the humidity fluctuations within the data center should be minimized. It is also recommended that the data center be positively pressured and have air curtains on entry ways to prevent outside air contaminants and humidity from entering the facility.
For facilities below 40% relative humidity (RH), EMC recommends using grounding straps when contacting the equipment to avoid the risk of electrostatic discharge
(ESD), which can harm electronic equipment.
Note
As part of an ongoing monitoring process for the corrosiveness of the environment,
EMC recommends placing copper and silver coupons (per ISA 71.04-1985, Section 6.1
Reactivity) in airstreams representative of those in the data center. The monthly reactivity rate of the coupons should be less than 300 Angstroms. When monitored reactivity rate is exceeded, the coupon should be analyzed for material species and a corrective mitigation process emplaced.

Floor load-bearing capacity
Storage arrays can be installed on raised floors. Customers must be aware that the load-bearing capacity of the data center floor is not readily available through a visual inspection of the floor. The only definitive way to ensure that the floor is capable of supporting the load associated with the array is to have a certified architect or the data center design consultant inspect the specifications of the floor to ensure that the floor is capable of supporting the array weight.
CAUTION
l l l
Customers are ultimately responsible for ensuring that the floor of the data center on which the array is to be configured is capable of supporting the array weight, whether the array is configured directly on the data center floor or on a raised floor supported by the data center floor.
Failure to comply with these floor loading requirements could result in severe damage to the storage array, the raised floor, subfloor, site floor and the surrounding infrastructure should the raised floor, subfloor or site floor fail.
Notwithstanding anything to the contrary in any agreement between EMC and the customer, EMC fully disclaims any and all liability for any damage or injury resulting from the customer’s failure to ensure that the raised floor, subfloor and/or site floor are capable of supporting the storage array weight.
The customer assumes all risk and liability associated with such failure.
Raised floor requirements
Best practice is to use 24 x 24 inch heavy-duty, concrete-filled steel floor tiles. If a different size or type of tile is used, the customer must ensure that the tiles have a minimum load rating that is sufficient for supporting the storage array weight. Ensure proper physical support of the system by following requirements that are based on the use of 24 x 24 in. (61 x 61 cm) heavy-duty, concrete-filled steel floor tiles.
Raised floors must meet the following requirements: l l
Floor must be level.
Floor tiles and stringers must be rated to withstand concentrated loads of two casters each that weigh up to 700 lb (317.5 kg).
Note
Caster weights are measured on a level floor. The front of the array weighs more than the rear of the configuration.
l l l l
Floor tiles and stringers must be rated for a minimum static ultimate load of 3,000 lb (1,360.8 kg).
Floor tiles must be rated for a minimum of 1,000 lb (453.6 kg) on rolling load.
For floor tiles that do not meet the minimum rolling load rate, EMC recommends the use of coverings, such as plywood, to protect floors during system roll.
Floor tile cutouts weaken the tile. An additional pedestal mount adjacent to the cutout of a tile can minimize floor tile deflection. The number and placement of
40 Site Planning Guide VMAX 250F, VMAX 450F, VMAX 850F, VMAX 950F with HYPERMAX OS
Physical weight and space l l l additional pedestal mounts relative to a cutout should be in accordance with the tile manufacturer’s recommendations.
Take care when positioning the bays to make sure that a caster is not moved into a cutout. Cutting tiles per specifications ensures the proper caster placement.
Use or create no more than one floor tile cutout that is no more than 8 in. (20 cm) wide by 6 in. (15 cm) deep in each 24 x 24 in. (61 x 61 cm) floor tile.
Ensure that the weight of any other objects in the data center does not compromise the structural integrity of the raised floor or the subfloor (nonraised floor) of the data center.

System bay layouts
The number of bays and the system layout depend on the array model, the customer requirements, and the space and organization of the customer data center.
Storage arrays can be placed in the following layouts: l l
Adjacent — all bays are positioned side-by-side.
Dispersed — dispersed layouts are provided with longer fabric and Ethernet cable bundles that allow 82 ft (25 m) of separation between system bay 1 and system bays 2 through 4.
Dispersed system bays require dispersed cable and optics kits and one set of side skins for each dispersed system bay in the configuration.
Note
n n
The routing strategy (beneath raised floor or overhead), site requirements, and the use of GridRunners (optional) or cable troughs can cause the actual distances to vary.
GridRunners are used to create a strain relief for all dispersed, under the floor, cable bundles. GridRunners are installed in the locations where the cable bundle enters and exits the area under the raised floor.
l
Adjacent and dispersed bays (mixed) layouts — allow both adjacent and dispersed layout within a single array.

Power distribution equipment, VMAX 250F
The VMAX 250F is powered by two redundant sets of power distribution equipment, one set for each power zone. Each set of power distribution equipment consists of a power distribution panel (PDP) and a power distribution unit (PDU).
The power distribution equipment is available in three wiring configurations: l l l
Single-phase
Three-phase Delta
Three-phase Wye
Note
The PDP AC power cords (single-phase and three-phase) extend approximately 10"
(25cm) above the bay egress for connection to the customer power supply. 15ft
(4.57m) extension cables are provided.
Each PDU provides the following components: l l
A total of 12 power outlets for field replaceable units (FRUs). The outlets are divided into three banks with each bank consisting of four IEC 60320 C13 individual AC outlets.
Each bank of outlets is connected to individual branch circuits that are protected by a single two pole 20 Amp circuit breaker.
l
PDP input connectors differ depending on the customer input power.
If the customer requires power to be supplied from overhead, the Overhead routing kit is available to route the power cables inside the machine through the top.

Power distribution unit VMAX 450F, VMAX 850F, VMAX
950F
The VMAX 450F, VMAX 850F, VMAX 950F arrays are powered by two redundant power distribution units (PDUs), one PDU for each power zone.
Both PDUs are mechanically connected together, including mounting brackets, to create a single 2U structure, as shown in the following figures. The PDUs are integrated to support AC-line input connectivity and provide outlets for every component in the bay.
The PDU is available in three wiring configurations that include: l l l
Single-phase
Three-phase Delta
Three-phase Wye
Note
The PDU AC power cords (single-phase and three-phase) extend 74" (188cm) from the PDU chassis and are designed to reach to the bay floor egress for connection to the customer power supply. 15' (4.57m) extension cables are provided.
Each PDU provides the following components: l l l
A total of 24 power outlets for field replaceable units (FRUs). The outlets are divided into six banks with each bank consisting of four IEC 60320 C13 individual
AC outlets.
Each bank of outlets is connected to individual branch circuits that are protected by a single two pole 20 Amp circuit breaker.
Depending on which PDU option selected there is a different input connector for each PDU.
If the customer requires power to be supplied from overhead, EMC recommends replacing the rear top cover of the bay with the ceiling routing top cover, described in
Overhead routing kit on page 110, which allows the power cables inside the machine
to be routed out through the top.
A second option is to "drop" the power cables down the hinge side, to the bottom, and route them inside the machine. The cables should be dressed to allow all doors to open freely and space should be provisioned accordingly to accommodate an adjacent cabinet.

Best practices: Power configuration guidelines
The following section provides best practice guidelines for evaluating and connecting power, as well as for choosing a UPS component.
Uptime Institute best practices
Follow these best practice guidelines when connecting AC power to the array: l l l l
The EMC customer engineer (CE) should discuss with the customer the need for validating AC power redundancy at each bay. If the power redundancy requirements are not met in each EMC bay, a Data Unavailable (DU) event could occur.
The customer should complete power provisioning with the data center prior to connecting power to the array.
The customer‘s electrician or facilities representative must verify that the AC voltage is within specification at each of the power drops being fed to each EMC product bay.
All of the power drops should be labeled to indicate the source of power (PDU) and the specific circuit breakers utilized within each PDU: n n
Color code the power cables to help achieve redundancy.
Clearly label the equipment served by each circuit breaker within the customer
PDU.
l
The electrician or facilities representative must verify that there are two power drops fed from separate redundant PDUs prior to turning on the array: n
If both power drops to a bay are connected to the same PDU incorrectly, a DU event will result during normal data center maintenance when the PDU is switched off. The label on the power cables depicts the correct connection.
l l
The electrician should pay particular attention to how each PDU receives power from each UPS within the data center because it is possible to create a scenario where turning off a UPS for maintenance could cause both power feeds to a single bay to be turned off, creating a DU event.
The customer’s electrician should perform an AC verification test by turning off the individual circuit breakers feeding each power zone within the bay, while the
Customer Engineer monitors the LED on the SPS modules to verify that power redundancy has been achieved in each bay.
One PDU should never supply both power zone feeds to any one rack of equipment.
Power extension cords, connectors, and wiring
The following section illustrates a variety of extension cords that offer different interface connector options. The selected cords are used to interface between the customer’s power source and each PDU connection.
The amount of cords needed is determined by the number of bays in the array and the type of input power source used (single-phase or three-phase).

EMC rack requirements for customer components
Customer components can coexist in an EMC rack with a VMAX 250F system. The system must be properly positioned within the rack in accordance with following physical placement rules: l l l l
EMC equipment should stack from the bottom while customer equipment stacks from the top of the rack.
A system must exist within contiguous space.
(Customer equipment must be above a VMAX 250F system and not interwoven within the EMC system.)
All customer equipment must be electrically isolated and powered by a second pair of PDP/PDUs. This pair is sold as an optional kit.
EMC racks with two VMAX 250F systems cannot install customer components in the rack.

Third Party Racking Option for VMAX 250F 93
Third Party Racking Option for VMAX 250F
Computer room requirements, VMAX 250F
The following computer room requirements provide service access and minimize physical disruption: l
A minimum of 42 inches (107 cm) front and 30 inches (76 cm) rear clearance is required to provide adequate airflow and to allow for system service.
Customer rack requirements, VMAX 250F
The array components are fully tested at the factory and then transferred to the minirack for shipping. Only EMC customer support engineers are authorized to install the system into a customer rack. The original shipping mini-rack, when empty, is returned to EMC after the installation is complete.
To ensure successful installation and secure component placement, customer racks must conform to the following requirements: l l l l l l
National Electrical Manufacturers Association (NEMA) standard for 19-inch cabinets.
Racks must be at least 38 inches deep, and provide 24 to 32 inch front-to-rear rail depth.
VMAX 250F systems require a minimum of 10U of continuous space for one V-
Brick (minimum configuration). 20U of continuous space is required for two V-
Bricks (maximum configuration).
Threaded hole racks are not supported.
The customer rack must have customer-supplied PDPs and PDUs installed and connected to customer power.
Customer rack must support a minimum 850 lbs (385 kg) of weight PLUS the weight of any 3rd party components within the rack.
l
Note
The customer must ensure floor load bearing requirements are met.
Components and cables installed in customer racks must conform to these configuration rules: n n
After installation, components and cables within the rack cannot be moved to available space in different rack, or to a different location within the same rack.
The system must be properly positioned within the rack in accordance with following physical placement rules: n
– Customer equipment can coexist within the same rack.
(Suggest that EMC equipment should stack from the bottom while customer equipment stacks from the top of the rack.)
– A system must exist within contiguous space.
(Customer equipment can be below or above the system, but not interwoven within the EMC system.)
Two, independent systems can coexist in a rack. The recommended configuration is:
94 Site Planning Guide VMAX 250F, VMAX 450F, VMAX 850F, VMAX 950F with HYPERMAX OS
Third Party Racking Option for VMAX 250F l l
– Lower system: 1U - 20U
– Upper system 21U - 40U
Round or square channel openings must support M5 screws that secure EMC rails and components. Clip nuts are provided by EMC as required.
To ensure proper clearance and air flow to the array components, customer supplied front doors and standard bezels, if used, must include a minimum of 2.5
inch (6.3 cm) clearance between the back surface of the door to the front surface of the vertical NEMA rails.
Front and rear doors must also provide: n n n
A minimum of 60% (evenly distributed) air perforation openings.
Appropriate access for service personnel, with no items that prevent front or rear access to EMC components.
Exterior visibility of system LEDs.
PDU requirements for third party racks, VMAX 250F
Customers must provide all power distribution equipment and infrastructure for a
VMAX 250F system installed in a customer rack.
General requirements:
l l l l l l l l
IEC 320-C13 outlets. Minimum quantity of six per PDU for no more than two V-
Bricks.
Carefully plan the connection of VMAX 250F hardware to the available IEC 320-
C13 outlets such that the VMAX 250F load current does not exceed the rating of any power distribution circuit breakers. Best practice is the circuit breaker operating current at nominal AC input voltage should not exceed 80% of the circuit breaker rating.
Refer to
Component power requirements, VMAX 250F
on page 95 for input requirements for each VMAX 250F component.
Refer to

Third party racks with vertical PDUs — RPQ Required
Each system bay is powered by two redundant power distribution units (PDUs), one
PDU for each power zone. Rather than use the standard EMC horizontal PDU, the customer can use vertical PDUs via RPQ. The general requirements for third party racks with rear-facing or inward-facing PDUs are listed below.

Requirements for third party racks with vertical PDUs (inward-facing)
on page
106
Requirements for third party racks with vertical PDUs (rear-facing) on page 104
General requirements for vertical PDUs within third party racks
In addition to meeting standard VMAX array power requirements, vertical PDUs should abide by the following: l l
Both PDUs support AC-line input connectivity and provide outlets for every component in the bay.
The PDU must be available in the wiring configuration that matches the customer power supply.
Options include: l n n
Single-phase
Three-phase Delta n
Three-phase Wye
Each PDU should meet the following requirements: n n n
At a minimum, a total of 24 power outlets must be provided.
The outlets are divided into six banks with each bank consisting of four IEC
60320 C13 individual AC outlets.
Each bank of outlets is connected to individual branch circuits that are protected by a single two pole 20 Amp circuit breaker.
The PDU capacity should exceed the power requirements shown in the Power
Calculator for the specific max configuration.
n
Single PDU mounted per side per Figure 32
on page 104 and Figure 33 on page
106.
If the customer requires power to be supplied from overhead, EMC recommends one of the following: l
Option 1: Replace the rear top cover of the bay with the ceiling routing top cover,
described in Overhead routing kit on page 110, which allows the power cables
inside the machine to be routed out through the top.
l
Option 2: "Drop" the power cables down the hinge side, to the bottom, and route them inside the machine.
The cables should be dressed to allow all doors to open freely, minimize cable congestion, and provide access to components within the system.

Chassis to chassis grounding
Rack to rack chassis ground connections are strongly recommended to mitigate the risk of large AC power transients in the data center affecting system performance.
Large AC power transients can occur from one or a combination of: electrical power grid problems feeding a facility; weak facility grounding; powerful lightning storm strikes; or facility power equipment failure. Mechanisms for tying racks together to provide the ground connection can vary based on the rack provided by the customer and site facility preference.
P/N 106-562-209 is a rack to rack grounding kit for EMC racks. The grounding kit may or may not work on racks provided by the customer due to the variety of ground location positions on racks.

Best Practices for AC Power Connections
Best practices overview for AC power connections
To assure fault tolerant power, external AC power must be supplied from independent, customer-supplied, power distribution units (PDUs) as shown in
on page
116.
NOTICE
For systems operating from three phase AC power, two independent and isolated AC power sources are recommended for the two individual power zones in each rack of the system. This provides for the highest level of redundancy and system availability.
If independent AC power is not available, there is a higher risk of data unavailability should a power failure occur, including individual phase loss occurring in both power zones.
NOTICE
Before connecting external AC power to EMC bays, verify that the bays have been placed in their final position as explained in the installation guide.

Procedure A, Task 3: Customer's electrician
NOTICE
This task is performed by the customer's electrician.
Procedure
1. Working with the EMC Customer Engineer, turn ON all the relevant circuit breakers in customer-supplied PDU 2.
Verify that only power supply and/or SPS LEDs in power zone A are ON or flashing green in every bay in the array.
Note
If all power supply and/or SPS LEDs in a bay are ON or flashing green, the bay is incorrectly wired because the AC power to both EMC power zones is supplied by a single PDU, that is, customer-supplied PDU 2. Wiring must be corrected before moving on to the next step.
2. Turn OFF the relevant circuit breakers in customer-supplied PDU 2.
Verify that the power supply and/or SPS LEDs that turned green in the previous step changed from green to OFF and/or flashing yellow. The yellow
SPS lights flash for a maximum of 5 minutes.
Note
Note that power supplies connected to an SPS continue to have green lights
ON while the SPS yellow light continues to flash indicating the SPS is providing on-battery power.
3. Repeat step 1 and step 2 for power zone B and customer-supplied PDU 1.
4. Turn ON all the relevant circuit breakers in customer-supplied PDU 1 and customer-supplied PDU 2.
5. Label the PDUs as described in PDU labels
on page 130.
