Removing the 175 MB Cache RAID – Dual IOA Enablement
card from the 17M/MB, 17M/MC, 79M/HB, or 79M/HC
Learn to remove an 175 MB Cache RAID – Dual IOA Enablement card in the 17M/MB, 17M/MC,
79M/HB, or 79M/HC server.
About this task
This feature is used to enable write cache on the two embedded SAS RAID controllers of the disk or
media backplane by providing the necessary rechargeable batteries for memory backup. It also enables
the two embedded SAS RAID controllers to work as dual storage IOAs, that is, high availability (HA)
RAID mode. This feature plugs in to the disk or media Backplane and enables a 175 MB write cache on
each of the two embedded RAID controllers by providing two rechargeable batteries with associated
charger circuitry. The write cache can provide additional I/O performance for attached disk or solid-state
drives, particularly for RAID 5 and RAID 6. The write cache contents are mirrored for redundancy
between the two RAID adapters resulting in an effective write cache size of 175 MB. The batteries
provide power to maintain both copies of write-cache information in the event power is lost.
To remove this card, complete the following steps:
Procedure
