Memory Mirror conditions
The DIMM is mounted following the ‘G.2.1 DIMM mounting sequence’.
The condition for the hardware is to have the same capacity as that of the mirroring DIMM group.
The condition for the hardware is to have the same capacity as that of the mirroring DIMM group.
Memory Mirroring
Memory Mirroring is executed in the memory on the same SB.
2.1.3 Hardware RAID
The Cisco C880 server supports Hardware RAID.
Hardware RAID is a RAID function that performs operations using the SAS array controller card. The SAS
array controller card is a PCI Express card having a dedicated RAID controller chip and firmware, and which
can control the array (faulty HDD disconnection, incorporation, LED control).
RAID levels supported in the hardware RAID are RAID0, RAID1, RAID5, RAID6, RAID1E, RAID10, RAID50,
and RAID60.
However, RAID level supported in the HDD/SSD on the SB and DU are RAID0, RAID1, RAID5, RAID6,
RAID1E, and RAID10.

Note
-
The logical volume configured with hardware RAID except for RAID0 cannot be used by Software RAID.
-
When using the hardware RAID, consider either of the following conditions to protect the customer’s data
in the event of a power failure.
in the event of a power failure.
-
An FBU is mounted.
-
Ensure stable AC power by redundant power mechanism, dual system reception mechanism, and UPS.
2.1.4 Cluster configuration
-
For inter-cabinet clustering, clustering with only Cisco C880 server is supported. The inter-cabinet
clustering with cabinets other than Cisco C880 server is not supported.
clustering with cabinets other than Cisco C880 server is not supported.
