IBM EJ1D 2D35 01DH407 Expanded Function Storage Backplane 18 SFF-3 Bays/Dual IOA with Write Cache/Opt Ext SAS port
The IBM 57D8 PCIe3 x8 Cache SAS RAID Internal Adapter 6 Gb is an internal PCI Express generation 3, serial-attached SCSI SAS Random Array of Independent Disks RAID adapter integrated in the IBM Power9 9009-41A, 9009-41G, 9009-42A, 9009-42G, 9223-42H, or 9223-42S system. The IBM 57D8 PCIe3 x8 Cache SAS RAID Internal Adapter 6 Gb is part of the composite feature of the IBM EJ1D and EJ1M Expanded Function Storage Backplane 18 SFF-3 Bays, Dual IOA with Write Cache and Optional External SAS port. The IBM 57D8 internal adapter has 00FX882 00MA020 00WV537 00WV518 00WV519 01JC715 00MA082 00MA083 00WV564 00WV565 00MA054 01LJ715 02DE387 02DE354 02DE343 01JC716 02DE371 02DE323 02DE372 part numbers and IBM EJ0P feature code.
The IBM 57D8 PCIe3 x8 Cache SAS RAID Internal Adapter 6 Gb feature is on sale in refurbished condition, includes warranty and technical support.
The IBM EJ1D and EJ1M Expanded Function Storage Backplane 18 SFF-3 Bays/Dual
IOA with Write Cache and Optional External SAS port. High performance controllers run SFF-3 SAS bays in the system unit. Dual controllers, also called dual I/O adapters or paired controllers and their write cache are placed in integrated slots and do not use PCIe slots. Write cache augments controller's high performance for workloads with writes, especially for HDD. 1.8 GB physical write cache is leveraged with compression to provide up to 7.2 GB cache capacity. The write cache contents are protected against power loss with flash memory and super capacitors removing the need for battery maintenance.
The high performance SAS controllers provide RAID-0, RAID-5, RAID-6, RAID-10, RAID-5T2, RAID-6T2, and RAID-10T2 support. Patented Active/Active configurations with at least two arrays is supported. Easy Tier function is supported so the dual controllers can automatically move hot data to attached SSD and cold data to attached HDD for AIX Linux VIOS environments. Small Form Factor (SFF) or 2.5-inch drives are mounted on a carrier tray specific to the system unit SFF-3. The backplane has 18 SFF-3 bays. This backplane also enables two SAS ports IBM EJ0W on the rear of the system unit support the attachment of one IBM EXP24S or IBM EXP24SX I/O drawer in mode1 holding HDD or SSD. Note that IBM EJ0W is an optional feature with IBM EJ1M and one x8 PCIe slot is used by EJ0W. Note this backplane doesn't support split backplane. For split backplane use IBM EJ1C + IBM EJ1E backplane features.
