Table 7. SAS RAID controllers supported for the 9040-MR9 system (continued)
Feature Code
Description Function
EJBB Storage backplane that uses a
PCIe3 SAS RAID quad port 6 Gb
x8 adapter for SAS bays in the
system unit
The base function storage configuration includes:
• One FC EJ0K adapter installed in C12 slot
• One base function disk drive backplane with 8x
SFF (2.5") bays
• One SAS AZ cable
SAS bays are 2.5-inch or Small Form Factor (SFF)
and used drives that are mounted on a carrier or
tray specific to the system unit (SFF-3). The high-
performance SAS controller provides RAID 0, 5, 6,
and 10 support for either HDD or SSD connectors.
JBOD for HDD is also supported. The SAS
controller has no write cache.
EJSB Storage backplane that uses two
PCIe3 SAS RAID quad port 6 Gb
x8 adapters for SAS bays in the
system unit
Base function storage configuration with split-disk
feature includes:
• Two FC EJ0K adapters that are installed in C09
and C12 slots
• One base function disk drive backplane with 8x
SFF (2.5") bays that are split into 4+4
• One SAS AZ cable
SAS bays are 2.5-inch or Small Form Factor (SFF)
and used drives that are mounted on a carrier or
tray specific to the system unit (SFF-3). The
storage bays are split into four storage bays each
per adapter. The high-performance SAS
controllers provide RAID 0, 5, 6, and 10 support
for the HDD or SSD connectors. JBOD for HDD is
also supported. The SAS controllers have no write
cache.
EJ0C Expanded function storage
backplane that uses dual PCIe3
12 GB Cache RAID Plus SAS
adapters
Expanded function storage configuration with dual
SAS Raid adapters includes:
• Two FC EJ14 adapters that are installed in C09
and C12 slots
• One expanded function disk drive backplane
with 8x SFF (2.5") bays
• One SAS AZ4 cable
• Two A12 SAS cables for adapter-to-adapter
attachment
All eight SSF-3 SAS disk bays are used by both
controllers. The high-performance SAS controllers
provide RAID 0, 5, 6, 10, 5T2, 6T2, and 10T2
support. JBOD is not supported for dual controller
configurations.
