IBM Power7 8202-E4B (#1912) - PCI-X DDR Dual Channel Ultra320 SCSI Adapter</p><p>The PCI-X DDR Dual Channel Ultra320 SCSI Adapter (#1912) is a 64-bit 3.3-volt adapter and is an excellent solution for high-performance SCSI applications. The PCI-X Dual Channel Ultra320 SCSI Adapter provides two SCSI channels (busses), each capable of running 320 MBps (max.). Each SCSI bus can only support external attach SCSI devices.</p><p>In order to achieve an Ultra320 SCSI bus data rate of up to 320 MB per second and maintain a reasonable drive distance, the adapter utilizes Low Voltage Differential (LVD) drivers and receivers. To utilize the 320 MB per second performance, all attaching devices should also be Ultra320 LVD devices; however, if Ultra2, Ultra3, or Ultra320 devices coexist on the same bus, each device will operate at its rated speed. For lower speed single-ended (SE) devices, the SCSI bus will switch to single-ended (SE) performance and interface to all devices on that SCSI bus at the lower SE bus data rate of the device.</p><p>Two VHDCI 68-pin connectors are mounted on the adapter's end bracket allowing attachment of various LVD and SE external subsystems. A 0.3-meter converter cable, VHDCI to P, Mini-68 pin to 68-pin, (#2118) can be used with older external SE devices or subsystems to allow connection to the VHDCI connector on the PCI-X DDR Dual Channel Ultra320 SCSI Adapter.</p><p>Two external ports provide connectivity to numerous other SCSI external subsystems. Check the external subsystem sales/web pages for verification of connectivity support with this adapter.</p><p>The PCI-X Dual Channel Ultra320 SCSI Adapter (#1912) is a native boot adapter. The adapter also supports target mode.</p><p>Limitations:</p><p>The two external ports do not support the connection to the IBM 7131-105 IBM Multi-Storage Tower Model 105.</p><p>The Dual Channel Ultra320 SCSI nonRAID Adapter has ports that are capable at running at ultra320 SCSI speeds (up to 320 MBytes/s).</p><p>Attributes provided: Attachment of external SCSI devices only on Power7 Servers.</p><p>Attributes required: One available 3.3 volt PCI or PCI-X slot or PCI-X 2.0 DDR slot</p><p>For 8202-E4B: (#1912)</p><p>Minimum required: 0</p><p>Maximum allowed: 24 (Initial order maximum: 0)</p><p>OS level required:</p><p>AIX Version 5.3 supported</p><p>AIX Version 6.1 supported</p><p>AIX Version 7.1 supported</p><p>SUSE Linux supported</p><p>Red Hat Linux supported</p><p>Refer to Software Requirements for specific O/S levels supported</p><p>Initial Order/MES/Both/Supported: Supported</p><p>CSU: Yes</p><p>Return parts MES: Does not apply</p><p>Note:</p><p>Not supported in the CEC</p><p>System maximum of 24 in 4 x #5796
