Caching for performance with Solid State Disk (SSD)
: With the exception of hard
drive slots 1 & 2 that are dedicated to OS hard drives, SSD(s) can be installed into all
other slots (starting from slot 3) to cater for desired performances (please refer to the
documents on the CD-ROM for configurations and contact your vendor for SSD
purchase details). You must also purchase a SSD-dedicated tray!
SAS / SATA hard drive for storage
: It is recommended to use hard drives that are
of the same brand, capacity, rotation speed and same model in an enclosure. RAID
arrays use a “least-common-denominator” approach meaning the maximum capacity
used in each drive for comprising a logical configuration is the maximum capacity of
the smallest drive.
Profile
: The enclosure drive trays are designed for 3.5-inch wide
x 1-inch pitch hard drives.
WARNING
Make sure all enclosure tray slots are filled a hard drive tray (with or with a hard
drive) as an empty tray slot may affect the airflow efficiency of the enclosure!
The hard drives should only be installed into the system
AFTER
the enclosure has
been rack mounted as the combined weight will be too heavy to handle.
Handle hard drives with extreme care and observe all ESD prevention methods
when installing drives.
Only use screws supplied with the system package. Longer screws may damage the
drive.
