VMAX All Flash packaging

VMAX All Flash arrays offer the simplest packaging ever delivered for a platform. The basic building block is an appliance-based entity called a V-Brick in open system arrays and a zBrick in mainframe arrays. Each V-Brick or zBrick includes: l l

An engine with two directors (the redundant data storage processing unit)

Flash capacity in Drive Array Enclosures (DAEs): l n n n

VMAX 250F: Two 25-slot DAEs with a minimum base capacity of 13TBu

VMAX 450F, VMAX 850F: Two 120-slot DAEs with a minimum base capacity of

53TBu

VMAX 950F (open or mixed systems): Two 120-slot DAEs with a minimum base capacity of 53TBu n

VMAX 950F (mainframe systems): Two 120-slot DAEs with a minimum base capacity of 13TBu

Multiple software packages are available: F and FX packages for open system arrays and zF and zFX for mainframe arrays.

This document uses the term V-Brick for planning purposes. All guidelines that apply to V-Bricks also apply to zBricks.

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.

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.

Fire suppressant disclaimer

Fire prevention equipment in the computer room should always be installed as an added safety measure. A fire suppression system is the responsibility of the customer.

When selecting appropriate fire suppression equipment and agents for the data center, choose carefully. An insurance underwriter, local fire marshal, and local building inspector are all parties that you should consult during the selection a fire suppression system that provides the correct level of coverage and protection.

Equipment is designed and manufactured to internal and external standards that require certain environments for reliable operation. We do not make compatibility claims of any kind nor do we provide recommendations on fire suppression systems. It is not recommended to position storage equipment directly in the path of high pressure gas discharge streams or loud fire sirens so as to minimize the forces and vibration adverse to system integrity.

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 cabling, cords and connectors

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.

Data centers must conform to the corresponding specification for arrays installed in

North American, International, and Australian sites.

VMAX 250F

Each system contains a complete set of power distribution equipment.

VMAX 450F, VMAX 850F, VMAX 950F

Each bay in a system configuration contains a complete 2U PDU assembly. The PDU assembly is constructed with two electrically individual PDUs.

NOTICE

Customers are responsible for meeting all local electrical safety requirements.

Customer input power cabling

Before the array is delivered, the customer must supply and install the required receptacles on the customer’s PDUs for zone A and zone B power for the system bay.

NOTICE

EMC recommends that the customer's electrician be present at installation time to work with the EMC Customer Engineer to verify power redundancy.

Refer to the EMC VMAX Best Practices Guide for AC Power Connections for required items at the customer site.

When connecting customer input power to a VMAX 250F, the EMC-supplied 15ft

(4.57m) extension cords must be used and approximately 24in (61cm) of slack must be left directly under the bay floor egress.

Note

For power zone-A, use the extension cord with gray sleeves at the ends.

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).

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

Power distribution equipment for third-party rack, VMAX 250F on page

98 for planning the number of connections required to support VMAX 250F components.

Two independent AC power zones with 4800 VA minimum rating for each zone.

200-240VAC, 50-60 Hz, available at each IEC 320-C13 outlet.

Ability to simultaneously turn On/Off all IEC C13 outlets within a power zone.

Distance from any component AC inlet connection to its corresponding C13 AC outlet can not exceed 66 inches (66 inches is the maximum AC cable length, including routing / service loop)

EMC does not recommend sharing the same power distribution equipment with customer equipment or multiple VMAX 250F systems. The customer assumes all responsibility for system power availability.

There are no cabling requirements; however, EMC recommends to use standard cabling diagrams as a guide to ensure load balancing.

Component cabling is performed by EMC field personnel during installation.

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

Figure 34

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.

Best Practices for AC Power Connections

Selecting the proper AC power connection procedure

The EMC Customer Engineer must select the proper AC power connection procedure

There are three possible scenarios at the installation site regarding the connection of customer AC power to the EMC array. The EMC Customer Engineer (CE) must select the proper AC power connection procedure for the scenario.

1. Refer to table below which summarizes the three possible scenarios at the installation site when you are about to connect external AC power to the EMC array.

2. Select the procedure that applies to your situation and follow the instructions for that procedure.

Table 38 Procedure options for AC power connection

If the scenario is...

then use this procedure:

The customer’s electrician is available at the installation site.

Best Practices for AC Power Connections

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
