PCIe1 SAS Tape/DVD Dual-port 3 Gb x8 Adapter (FC EJ1P and EJ1N; CCIN 57B3)

Overview

FC EJ1P and EJ1N are both the same adapter with different tail stock brackets. FC EJ1N is a low-profile adapter and FC EJ1P is a full-height adapter. FC EJ1P and EJ1N are functionally identical to FC 5901 and 5278, but designates to IBM configurator tools that the usages are tape and DVD, not disk.

The PCIe1 SAS Tape/DVD Dual-port 3 Gb x8 Adapter is a PCI Express (PCIe) generation 1 (Gen1), x8 adapter. The adapter is for high-performance, high-density, and serial attached SCSI (SAS) applications. It supports the attachment of SAS tape and DVD by using a pair of mini-SAS 4x connectors. The mini-SAS 4x connectors allow the adapter's eight physical links to be used in various narrow and wide-port configurations. The adapter can also be used for external tape drives, which are not supported on the newer and faster four-port 6 Gb PCIe3 adapters. The adapter does not have write cache.

The PCIe1 SAS Tape/DVD Dual-port 3 Gb x8 Adapter is a 64 bit, 3.3 V, bootable SAS adapter.

Externally attached devices are designed to run at a data rate of 1.5 Gbps for serial ATA (SATA) devices, and 3 Gbps for SAS devices.
