SCSI Adapters
SCSI is an ANSI standard bus that allows connection of peripherals such as disks and tapes to a computer system. There are up to 15 available SCSI device
addresses on each Host Adapter Card. Most SCSI peripheral devices use one SCSI address. The Optical Disk Jukebox uses two to seven SCSI addresses (one
for each Magneto-Optical drive and one for the Autochanger "picker" mechanism) for the first six drives, and a second SCSI Host Adapter Card with two to
six SCSI addresses for drives 8-12.
SCSI peripherals (disks and tapes) can be mixed and matched in any combination on the same SCSI bus as long as the total number of SCSI devices does
not exceed seven. However, mixing disks and tapes on the same adapter card is not recommended due to potential performance degradation.
Information on SCSI RAID adapters is contained later in this QuickSpec.
NOTE: Use of third-party peripherals is at user's risk and is not supported by HP's standard support process.
The following table shows the SCSI adapters available for use on HP 9000 and HP Integrity Servers, the maximum number of cards supported on each
platform, and whether the adapter supports boot.

Comparing SCSI Interfaces
HP UNIX Enterprise Servers users may choose from three industry-standard I/O interfaces. The following table summarizes the key characteristics of SE, FWD,
and Ultra2 LVD/SE SCSI.
NOTE: Although Fast/Wide/Differential SCSI and single-ended SCSI are both SCSI-2 compliant, SE devices may not be connected a to FWD SCSI bus.

Restrictions and Limitations
1. Do not connect single ended SCSI-2 or Ultra2 LVD peripherals to FWD SCSI-2 interface cards. They are not compatible.
2. FWD SCSI 2 interface cards and single ended SCSI-2 cards may coexist in the same system.
3. FWD SCSI disks and FWD disk arrays may be mixed on the same card.
Fast/Wide/Differential SCSI-2 Description
The SCSI address of a device dictates the device's priority when arbitrating for the SCSI bus. SCSI address "7" is the address for the highest priority device (and
is usually reserved for the host). Address '7' is followed in priority (from highest to lowest) by the subsequent addresses 6, 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11,
10, 9, and 8. Fast/Wide/Differential SCSI disk arrays and Fast/Wide/Differential SCSI disks can be mixed on the same card.
Under extreme I/O workload conditions, it is possible for lower-priority devices on a Fast/Wide/Differential bus to be "starved" for data throughput and time
out. A retry will be automatic.
Similar to single ended (SE) SCSI, devices on the Fast/Wide/Differential SCSI bus are connected to each other in a "daisy chain." The first and last devices on
the SCSI bus must provide proper termination on the bus. A terminator, which fits on a SCSI connector, is shipped with the adapter card and can be used to
terminate the last device on the SCSI bus.
The Fast/Wide/Differential SCSI card is customer installable. The average installation time for the card is 15 minutes.

Storage Adapters for HP UNIX Enterprise Servers
SCSI Adapters
FWD SCSI Termination and Cabling
Both end points on a SCSI bus must be terminated. The adapter will supply termination to one end of the bus. The other end of the bus must be terminated as
well. Use terminators to terminate the peripheral end of the SCSI bus. High-density FWD terminators are included with all the FWD adapters except the
A5159A.
The A5159A is dual ported and has VHDCI connectors. Terminators are not included with the A5159A since the final device in the SCSI chain may be HD or
VHDCI. Thus the appropriate terminator should be ordered separately and utilized on the final device in the SCSI chain. Currently most FWD devices have
HD connectors and in those cases a 68 pin HD HVD terminator should be ordered. That is C2905A: 68-pin HD High Voltage Differential Terminator.
The A5159A adapter has self-termination when no cable is attached to the connector. This means that when the card is installed, but no cable is attached,
the card does self termination at the connector. Thus there is no need to add external terminators directly to the card connectors.
See the Service and User Guides with each card for information on how to disable the automatic self-termination for HA configurations utilizing V-cables
and/or in-line terminated cables. On this subject, more information is forthcoming in this QuickSpec.
All other FWD cards do NOT have self-termination. When the card is installed in the system it needs to have terminators attached when not hooked to a
properly terminated SCSI chain.
The Fast/Wide/Differential cards (A4800A, A5159B and A5159A) use high voltage differential transceivers that support cable distances up to 25 meters.
When considering cable distances, however, all cable distances must be added, including cable from the host to the first storage device, cable consumed
within the storage enclosure, and cable from storage device to storage device.
A Fast/Wide/Differential SCSI tower enclosure consumes 1.3 meters of Fast/Wide SCSI cable internally. A rackmount Fast/Wide/Differential SCSI storage
enclosure consumes 1.75 meters. A Fast/Wide/Differential SCSI disk array consumes 0.7 meters of cable. Be sure to include these values in your calculations.
There are four types of Fast/Wide/Differential SCSI cables:
1. Standard male-male, 68-pin, high-density cable, which can be used to cable from the host adapter to the first peripheral and from peripheral to
peripheral. These cables are available in 0.9-, 2.5-, 5-, and 10-meter lengths.
2. An extender cable that is also 68-pin high-density with one male and one female connector. This cable can be used to extend the cable from the
adapter to a peripheral or to extend the peripheral to peripheral cable. Extender cable lengths available are 2, 5, and 10 meters.
3. V-cable, 68-pin, high-density, male/male/male.
4. V-cable, 68-pin, high-density, male male female. This cable is used with an extender to go host-to-host; use an external terminator on the last host.
The A5159A PCI Dual Port FWD SCSI Adapter uses Very High Density connectors (VHDCI). The cables needed for attaching to VHDCI on the adapter and
high density (HD) on the peripheral are:
C2361B-1.0-meter 68-pin VHDCI to 68-pin HD Multimode SCSI Cable
C2362B-2.5-meter 68-pin VHDCI to 68-pin HD Multimode SCSI Cable
C2365B-5.0-meter 68-pin VHDCI to 68-pin HD Multimode SCSI Cable

C2375A-1.0-meter 68-pin VHDCI to 68- pin HD Multimode In-Line Termination SCSI Cable

SCSI Adapters
Ultra2 LVD/SE SCSI Termination
The host adapter supplies termination power. Any or all of the devices on the bus may supply termination power. The first two devices that supply termination
power should be located at each end of the SCSI bus. Other devices supplying termination power can be placed anywhere along the bus.
Both end points on a SCSI bus must be terminated. The adapter will supply termination to one end of the bus. The other end of the bus must be terminated
as well. Use active terminators as described above to terminate the peripheral end of the SCSI bus. The terminators are not included with the adapter card
and need to be purchased separately when needed. Sometimes terminators will come with the SCSI peripheral storage device.
All three of the Ultra2 LVD/SE SCSI adapters have self termination when no cable is attached to the connector. This means that when the card is installed,
but no cable is attached, the card does self termination at the connector. Thus there is no need to add external terminators directly to the card connectors.
See the Service and User Guides with each card for information on how to disable the automatic self termination for HA configurations utilizing V-cables
and/or in-line terminated cables. On this subject, more information is forthcoming in this guide.
SCSI Usage Guidelines
Power on all SCSI peripherals and make sure they have time to complete their self test before powering on the System Processor Unit (SPU).
NOTE: Some devices require termination power to pass the self test. These devices may fail self test if they are powered on before the host. If this
occurs, the system will still boot up successfully and clear the error on the device.
Power on all SCSI peripherals that provide termination power first.
Keep all devices powered on during and after system boot-up.
Do not add or remove SCSI devices while the system or any SCSI peripheral providing term power is powered on.
Optimal Number of Disks per Interface Card
Disk I/O performance is governed by two factors:
1. The data throughput rate of the I/O channel and disks
2. The way the application(s) access data on the disks. The following information is meant to be used as guidelines rather than rules.

Each of the following should be placed on separate spindles for optimal performance (high to low priority order):
Indices (especially indices that are accessed concurrently)
Logfiles
Tables that are accessed concurrently

Fibre Channel Products
Fibre Channel is an ANSI-standard data transfer interface technology designed for high-bandwidth, high-performance interconnects between servers and
storage devices, such as disk arrays and tape subsystems. Fibre Channel is becoming the choice for server to storage interconnect. FC is also becoming the
technology of choice for SANs. Compared to SCSI, Fibre Channel offers much more flexibility in storage configurations. Fibre Channel gives you significantly
greater distance between devices, greater number of total devices, and the ability to connect devices through hubs and switches. Hewlett Packard offers Fibre
Channel Interface adapters and Fibre Channel to SCSI Multiplexer adapters for HP UNIX Enterprise servers.
FC hardware topologies include point-to-point, arbitrated loop (FC-AL) and switched (FC-SW). HP offers all three solutions for their servers. The three
topologies involve very different levels of initial investment and deliver different combinations of availability, scalability, performance and manageability.

Fibre Channel Products
Point-to-Point Connections Offer Simplicity and Flexibility
Simply connecting two nodes with a link automatically establishes a point-to-point connection. One of them will become port 1 and the other port 0 based
on their relative Worldwide Names.
With Fibre Channel, even point-to-point topology, the simplest configuration, offers you significant advantages. For example, high availability can easily be
achieved with a local server storage configuration cross-connected to a remote server storage configuration. Because of the extended distance support with
Fibre Channel, the remote device could even be in another building.
Loops and Hubs for Connectivity
FC-AL (Fibre Channel Arbitrated Loop) is the low-cost FC alternative. FC-AL connects up to 127 nodes in a loop. Optional hubs are used to provide non
disruptive pluggability by implementing a star configuration that acts as a logical loop. If the aggregate bandwidth requirement of the nodes on a loop is
less than the bandwidth of the loop, then a loop-based connection scheme will likely satisfy performance needs as well as connectivity requirements.
High-availability server environments can use redundant hubs, host bus adapters (HBAs) and links to provide alternative paths for failover. For simple server
and storage configurations, FC-AL will continue to offer the initial benefits of an FC host connection-flexible connectivity, distance, bandwidth and basic
resource sharing-at an affordable cost. More advanced FC hub devices support FC loop connections while offering some of the benefits of switches. The
arbitrated loop organizes up to 127 Fibre Channel ports on a ring, and distributes the routing functions among them. The arbitrated loop lets two ports
communicate with one another in a full-bandwidth, full-duplex link (like the point-to-point example). However, unlike switches, hubs make all traffic in the
configuration available to all devices.
The arbitrated loop is similar to a SCSI bus, but with several dramatic advantages, including many more nodes, much higher data rates, and a full-duplex
link rather than a half-duplex connection. The arbitrated loop configuration is well-suited to a storage server and disk drives in JBODs (just a bunch of
disks). It is significantly less expensive than a Fibre Channel switch, and from a system perspective, comparable to SCSI in cost.
While the primary advantage of the arbitrated loop is cost per port, it has several disadvantages when compared with switched topologies. These include
limited connectivity and bandwidth, transit delay from serial links and the buffers in each repeater, time- consuming loop initialization (LIP) and arbitration
protocols, and higher error rates because signals go through many more links. The hub also adds cost to a loop, but simplifies wiring and may enable the
user to add management functions and deal more gracefully with failures and hot swap issues.
Switches for Scalability, Performance and Availability
Fibre Channel Switched Fabric can interconnect up to 16 million nodes. Physical links can be 10 km or longer if they use single mode fiber, so a fabric may
involve switches distributed over several buildings or over a metropolitan area. Switches are preferred when supporting large numbers of servers and storage
connections. Switches provide scalability by enabling a Fibre Channel fabric to support hundreds or even thousands of server and storage nodes-well beyond
the addressing capability of a single arbitrated loop or hub connection. Each storage node can attach directly to a switched fabric port; or multiple storage
nodes can attach to a loop that also contains a fabric connection port. Fibre Channel switches provide higher performance-close to the full Fibre Channel
data rate of 200 MB/sec-for each connection between input and output ports. A switch can improve performance by buffering the incoming data from each
server, until the data can be passed on to the storage device. Finally, switches enhance availability. In a pure loop configuration, a host reset or device
failure can cause a loop initialization that resets all the other devices on the loop; this interrupts the loop's availability to other servers and storage devices. A
switch can prevent this kind of error propagation and can also enable rapid isolation and repair of hardware device failures.

Storage Adapters for HP UNIX Enterprise Servers
RAID Controller Cards
RAID (Redundant Array of Inexpensive Disks) provides high performance storage and full data redundancy in case of disk failure.
With the explosive growth of critical computing in both large and small businesses, there has been an ever increasing need to find better ways of storing and
securing large amounts of data. Businesses demand a means of data storage and failure protection that ensures continuance in the event of a failure that
would otherwise cripple their mission critical applications. The basic idea of RAID is to combine multiple small, inexpensive disks into an array that appears
as a single logical storage unit or drive. The data is distributed across the disks in order to provide a method for data recovery or reconstruction in the event of
a drive failure.
Please see the SCSI section in this QuickSpec for detailed information on understanding SCSI technologies including Ultra2 LVD/SE.

RAID 4si (A5856A)-4-port Ultra2 SCSI RAID Information
Recommended Minimum Configurations
In order to maintain reasonable system performance, the following guidelines are recommended:
One 360-MHz Processor (PA-8500) and 500 MB of memory supports up to three A5856A RAID 4si Cards.
One 550-MHz Processor (PA-8600) and 500 MB of memory supports up to four A5856A RAID 4si Cards.
Additional Processors and Memory are recommended for systems with more than three to four A5856A RAID 4si Cards.
Compatibility
SCSI
The A5856A RAID 4si card is compatible with Wide Low Voltage Differential (LVD) devices. Typically these devices are called Ultra2 SCSI devices.
Most of these devices can handle a connection to either LVD or SE SCSI adapters. When running in LVD mode the max speed is normally Ultra2 (80
MB/s) or Ultra (40 MB/s) depending on the capability of the device. When running in SE mode the speed is normally Ultra or lower. See "Setting the
Speed" below.
It is also compatible with all Wide Single Ended (SE) devices. Single Ended devices range in speed from Normal (5 MB/s), to Fast (20 MB/s), to Ultra
(40 MB/s). The A5856A will automatically adjust to the correct speed when set up properly, see "Setting the Speed" below.
The A5856A RAID 4si is NOT compatible with HVD (High Voltage Differential) devices. This would include most devices marked as
Fast/Wide/Differential or Ultra/Wide/Differential.

Cables and Terminators for SCSI
Cabling
LVD/SE SCSI allows up to 15 disk devices on each SCSI channel. The disks are hooked together in a "daisy chain" fashion. LVD SCSI supports cables lengths
of 12 meters and SE SCSI supports cable lengths of 6 meters. Care should be taken to include all cable lengths when making the calculation-including
internal cables and backplanes in systems and disk enclosures.
Cables are typically sold with the SCSI peripherals. The A5856A has 68-pin VHDCI (Very High Density) SCSI connectors. Some disks and disk enclosures
have 68-pin HD (High Density) connectors and other have 68-pin VHDCI connectors. The cable therefore should have the correct connectors on each end.
Termination
The A5856A RAID 4si has automatic self-termination. When there is no cable attached to an external port, the card will automatically terminate that port.
Thus when no cable is attached to the port a terminator is not required on that port.
As with all SCSI configurations, both ends of the SCSI bus MUST be terminated. The A5856A adapter will terminate on one end, however the final SCSI
device in the SCSI chain must also be terminated. Some devices come with terminators and others do not.
Always be sure to acquire the correct terminator for the final device in the SCSI chain and install it. The A5856A does not come with a terminator. Unless you
already have one or one comes with the final device in your SCSI chain, you must order it separately.
We recommend the following terminators:
For connecting to LVD or SE devices with 68 pin HD connectors:
C2364A-68-pin HD (High Density) LVD/SE Multi mode SCSI Terminator
For connecting to LVD or SE devices with 68 pin VHDCI connectors:
C2370A-68-pin VHDCI (Very High Density) LVD/SE Multi mode SCSI Terminator
See the SCSI section in this QuickSpec for more information on terminators.
Setting the Speed/Data Rate
The normal procedure for setting the date rate in SCSI is a negotiation between the SCSI Host Bus Adapter and the SCSI device connected. When both are
powered up they will communicate to find out the speed capability of each other. Then they agree on the clocking speed to be used based on the highest
common speed capability. For example: When an Ultra2 (80 MB/s) LVD Adapter is connected to an Ultra (40 MB/s) LVD disk drive, they both agree to
default to the Ultra (40 MB/s) speed since that is as fast as the disk drive can operate.
See the SCSI section in this QuickSpec for more detailed information on understanding SCSI technology including SCSI data rates negotiation.
The A5856A speed setting is set using the internal RAID configuration tool, IRM.
