SATADO A quick memory storage media unit that features high energy
M efficiency and stability. It is a SATA SSD or SATADOM electrical
hard disk.
SATADOMs use flash memory to store data. Currently, NAND flash
memory is mostly used in the industry. NAND flash memory stores
electrons on the floating gate to store data. However, electrons
frequently passing through the floating gate will weaken the gate's
ability to store electrons and eventually make the gate unable to store
electrons. This problem is common to NAND flash memory. The
amount of service data to be written needs to be assessed to prevent
component failures.
NOTE
l If the SoftRAID function is enabled on the server, the STATADOM
supports SoftRAID, which supports RAID 0 and RAID 1.
l A SATADOM can be used only as a boot disk for Linux OSs.
l SATADOMs have weak endurance and cannot be used as data storage
devices. Use enterprise-level HDDs or SSDs to replace SATADOMs for
data storage when frequent data erase operations are involved.
l Installing write-intensive service software on SATADOMs will accelerate
the write life consumption and result in perpetual damage of SATADOMs.
SATADOMs cannot be used for such services.
l SATADOMs cannot be used in cache scenarios.
l The 5288 V3 supports two SATADOMs. The mappings between the
physical positions and the port numbers in the BIOS are as follows: SATA1
– PORT4; SATA2 – PORT5.
