PCI-X DDR External Dual – x4 Port SAS Adapter (FC 5900 and 5912; CCIN 572A)

Learn about the specifications and operating system requirements for the 5900 and 5912 adapter.

Overview

The Peripheral Component Interconnect-X (PCI-X) DDR External Dual – x4 Port SAS Adapter is a low-profile adapter for high-performance and high-density, serial-attached SCSI (SAS) applications. The adapter provides two mini SAS 4x connectors, which allow the eight physical links to be used in various narrow and wide-port configurations. The adapter is a 64-bit, 3.3 V, bootable SAS adapter that provides RAID 0, 5, 6, and 10 capability. Some RAID level support is operating system dependent. The adapter provides RAID 0, RAID 5, RAID 6 and RAID 10 for AIX® and Linux. Under the IBM® i operating system, mirroring and data spreading is provided by the operating system and RAID 5 and RAID 6 is provided by the adapter.

The adapter does not have write cache. (The write performance of RAID level 5 and RAID level 6 may be poor on adapters which do not provide write cache. Consider using an adapter which provides write cache when using RAID level 5 or RAID level 6.)

The adapter can address up to 48 SAS disk drives, although the actual number of drives in a system is subject to the physical placement limitations of the system. Externally attached devices are designed to run at a data rate of 1.5 Gb/s for Serial Advanced Technology Attachment (SATA) devices, and 3 Gb/s for SAS devices. This card supports RAID and non-RAID DASD, tape, and optical devices. Feature 5912 supports the multi-initiator and high availability configurations in the AIX and Linux operating systems. The IBM i operating system does not support feature 5912 in multi-initiator and high availability configurations.

This adapter does not support solid state drives (SSDs). For more information about SSDs, see the topic Installing and configuring solid state drives.

Important: See the following topics for more information and important considerations for multi-initiator and high availability configurations: SAS RAID controllers for AIX, SAS RAID controllers for IBM i, or SAS RAID controllers for Linux. See also Important partitioning considerations with dual-slot and multiadapter configurations.

5900: 44V3296*
5912: 44V4413*
* Designed to comply with RoHS requirement.
I/O bus architecture
PCI-X DDR
Slot requirement
One available PCI-X slot
If the adapter is used with the feature 3650 or 3651 cable card, the cable card occupies slot P1-C3 in the 9117-MMA system unit. Features 3650 and 3651 are only supported in the model 9117-MMA.
Cables
SAS device attachment requires specific cables that are provided with the subsystem or device features being attached. Special cabling is required for multi-initiator and high availability configurations. See Serial attached SCSI cable planning.
Voltage
3.3V
Form factor
Short, low-profile
Maximum number
For system-specific adapter placement information, see the PCI adapter placement for machine types 82xx and 91xx or the PCI adapter placement for machine type 94xx topic collections.
Attributes provided
  • Two external mini SAS 4x connectors provide attachment of SAS and SATA device enclosures
  • SAS Serial SCSI Protocol (SSP), Serial ATA Tunneling Protocol (STP), and Serial Management Protocol (SMP)
  • RAID 0, 5, 6, 10

    The write performance of RAID level 5 and RAID level 6 may be poor on adapters which do not provide write cache. Consider using an adapter which provides write cache when using RAID level 5 or RAID level 6.

  • Concurrent firmware update
  • Removable media device supported (Removable media is not supported in multi-initiator and high availability configurations)
  • 440 - 500 Mhz PowerPC® (PPC)
  • Support for multi-initiator and high availability configurations (5912)

Operating system or partition requirements

This adapter is supported for the following operating systems:
The following versions are required for multi-initiator and high availability support:
  • AIX Version 6.1 with the 6100-01 Technology Level, or later
  • AIX 5L Version 5.3 with the 5300-08 Technology Level, or later
  • Red Hat Enterprise Linux version 4, with update 7, or later
  • Red Hat Enterprise Linux version 5, with update 2, or later
  • SUSE Linux Enterprise Server 10, with service pack 2, or later

This adapter requires the following drivers:

If you are installing a new feature, ensure that you have the software required to support the new feature and that you determine if there are any existing prerequisites. To do this, use the IBM Prerequisite Web site at http://www-912.ibm.com/e_dir/eServerPrereq.nsf Link outside information center.

POWER5 restrictions

When the feature is used in a POWER5 based system configuration, the following restrictions apply:
  • A maximum of two 5886 EXP 12S Expansion drawers can be attached per controller with one on each port. No cascading.
  • AIX and Linux support only. IBM i is not supported.
  • AIX and Linux load source capability is not provided.
