How to check whether the physical status of the hard drive properly S5000 system?

SCSI read during the interactive process, start to interact with the target startup process than writing
less and the target device, the main goal is the process of writing assignment needs to be cached.
Because SAS is a serial SCSI, so the transfer rate is usually lower than parallel SCSI.
For the S5000 and S2600 systems, DB configuration information is stored in the system, when the
record on safe electrical system controller reads the disk DB, if you have a DB is inconsistent with
other DB storage device into safe mode will not work properly, DB need to synchronize information
With the same specifications, the number of hard drives in the RAID group established in reading and
writing in the same business, Raid10 random write performance and Raid5 random write
performance is roughly equal.
