#2757
(cont.)
#2757 PCI-X Ultra RAID Disk Controller
The number of arrays and size of each array can be influenced by specifying an optimization of either
Balance,
Performance, or Capacity in iSeries Navigator when starting arrays. An optimization of Balance is used by default when
starting arrays from DST or SST options. If disk units are included in an existing array, parity might be spread across less
than the preferred number of disk units. In this case, the RAID function must be stopped and then started to redistribute
the parity.
The #2757 controls up to two removable media devices (internal tape, CD-ROM and DVD).
The #2757 does not support DASD compression.
Minimum operating system level: OS/400 V5R2
The #2757 is a Customer Install Feature.
#2763 #2763 PCI RAID Disk Unit Controller
The #2763 is an Ultra2 SCSI controller with a 10 MB write-cache that provides RAID-5 protection for internal disk units and
supports up to two removable media devices (internal tape units and CD-ROM units). In addition to providing RAID-5
protection for disks, the #2763 is also designed to work as a high performance controller for disks protected by system
mirroring or disks with no protection. The #2763 controller supports a maximum of 12 disk units.
A minimum of four disk units of the same capacity are needed for a valid RAID-5 configuration. A maximum of three arrays
are allowed per controller, with a maximum of 10 disk units allowed per one array. All disk units in an array must be of the
same capacity. Parity is spread across four disk units for arrays of four to 10. The #2763 does not support hardware disk
compression. The #2763 does not support the #4331 1.6 GB Read Cache Device.
One #9767 and one #2763 are allowed in the system unit if the #0041 is not selected. Two #2763s and the #9767 are not
allowed.
Requires a long PCI card slot
Minimum operating system level: OS/400 V4R5
The #2763 is a Customer Install Feature.
The #2763 was withdrawn from marketing on 21 November 2003 for new orders. Conversions to feature #2763 remain
available. The #5703 PCI-X RAID Disk Unit Controller is the recommended replacement.
#2765 #2765 PCI Fibre Channel Tape Controller
The #2765 provides Fibre Channel attachment capability for external tape devices. The #2765 supports point-to-point and
arbitrated loop topologies and has an LC type cable connector. Each #2765 is shipped with a wrap connector (P/N
05N6767).
The devices supported for Fibre Channel attachment are:
3534-1RU SAN Fibre Channel Managed Hub (1 Gbps)
Fibre Channel Switches:
– 2109 S08/S16 (1 Gbps)
– 2109 F16 (2 Gbps)
– 3534 F08 (2 Gbps)
3583-Lxx Ultrium Scalable Tape Library with an #8005 SAN Data Gateway Module
3584-L32 or D32 Ultrascalable Tape Library
3590 ½-inch Cartridge Tape Subsystem Models E11 and E1A
The #0163 Fibre Channel Attach Specify is required for each device attaching to an iSeries server with a #2765. The
following adapter kits are required when connecting SC type cables to the #2765:
#0371 - LC-SC Adapter Kit (50 um) can be ordered on initial, model upgrade, and MES orders. This optional kit is
used to attach SC- type fibre (50 micron) cables to a #2765. This kit contains a 2 m LC-ST cable and ST-SC adapter
for 50 micron fiber.
#0372 - LC-SC Adapter Kit (62.5 um) can be ordered on initial, model upgrade, and MES orders. This optional kit is
used to attach SC-type fibre (62.5 micron) cables to a #2765. This kit contains a 2 m LC-ST cable and ST- SC
adapter for 62.5 micron fiber.
An optics cleaning kit (P/N 46G6844) and instruction sheet instruction sheet (P/N 21P6238, form number SY27-2604) is
supplied, one per system, when a #2765/#2766 is ordered.
Multi-target support with maximum of 16 targets with V5R2
The #2765 does not support the Alternate IPL device function. A D-mode IPL is required using CD-ROM, DVD-ROM, or
another alternate IPL tape device. Then select a #2765 to complete the installation or recovery process.
Minimum operating system level: OS/400 V5R1
The #2765 is a Customer Install Feature.
The #2765 was withdrawn from marketing on 01 October 2004. The recommended replacement is a #5704 PCI-X Fibre
Channel Tape Controller.
