PCIe3 x8 cache SAS RAID Internal Adapter 6 Gb (FC EJ1G and FC EL67; CCIN 57DC)
Learn about the specications and operating system requirements for the PCIe3 x8 cache SAS RAID
internal adapter 6 Gb (FC EJ1G and FC EL67) that is integrated with the expanded function Random Array
of Independent Disks (RAID) feature composite storage backplane.
Overview
The expanded function PCIe3 x8 cache SAS RAID internal adapter 6 Gb is an internal PCI Express
generation 3 (PCIe3), serial-attached SCSI (SAS) RAID adapter. The adapter is part of a composite
feature of the storage backplane (FC EJ1G and FC EL67) and contains the SAS RAID controller.
The high-performance internal adapter is preinstalled in the dedicated internal PCIe3 x8 slot P1-C49 and
its back power module in P1-C49-E1. The composite storage feature (FC EJ1G and FC EL67) provides the
following features:
• A storage backplane (CCIN 2D36) that provides slots for eight 2.5 inches small form-factor (SFF) hard
disk drives (HDDs) or solid-state drives (SDDs).
• A PCIe3 cache SAS RAID internal adapter (CCIN 57DC) is installed in the slot P1-C49.
• The backup power module card is installed in slot P1-C49-E1.
• One mini-SAS HD cable that attaches to the high-performance storage backplane.
• A mini-SAS HD cable with an external SAS port that is installed in the system rear bulkhead in the slot
P1-C10.
The PCIe3 x8 cache SAS RAID internal adapter 6 Gb is a single stand-alone adapter that has a data read/
write speed of 6 Gb/s and a real write cache of 1.8 GB. With a 4:1 cache compression, this high-
performance adapter provides an increased cache of 7.2 GB and increases the storage system
performance. With this single cache adapter conguration, there is only one copy of the write cache data.
The write cache contents are protected against power loss with flash memory and super capacitors that
remove the need for cache battery. The super capacitors are part of the backup power module card which
is installed in slot P1-C49-E1.
