Re: installtion in array controller
After configuring the RAID settings, the system spends quite a while actually synchronizing the data between the physical disks of the RAID array. During that time, you can use the server as normal, but disk performance will be less than expected because part of the disk bandwidth is going to syncing the array. It is also overwhelmingly sequential work, so it is not likely to produce any cache hits.
Is your system equipped with a backup battery for the RAID cache?
While the battery is being charged, the write cache is disabled, to minimize the amount of data loss if power is suddenly lost. When the battery has sufficient charge, the write cache should be automatically enabled.
