Installation Guide
There are four tiers within JBOD topology as above:
First tier is a RAID System.
Second tier is a SAS JBOD with a SAS CH0 on it. Connecting SAS CH0 to SAS
exp. Port on RAID System via a MiniSAS HD Cable.
Third tier could be two SAS JBODs with a SAS CH0 port individually. One is
connected to the SAS EXP. Port on the second tier SAS JBOD via a MiniSAS HD
Cable. Another is connected to the SAS CH1/E Port on the second tier SAS JBOD
Fourth tier is a SAS JBOD with a SAS CH0 on it. Connecting SAS CH0 to SAS exp.
Port on third tier SAS JBOD via a MiniSAS HD Cable.

When cabling is completed, RAID system + 12Gb/s SAS JBOD system can be
turned on. This should be done in the following order:
1. First turn on the power switch of 12Gb/s JBOD system.
2. Then turn on the power switch of RAID system
3. Power on and boot the host computer(s)

AccuSTOR Gen2 subsystem do not require the installation of different
drivers for use with different operating systems. AccuSTOR Gen2 system
is independent and transparent to the host operating system.
It is often recommended to install the hard drive with same brand, model
no., interface and capacity in this RAID subsystem.
Please do not install SAS and SATA hard drives at the same time, as
these hard drives spin at different speed and may lead to compatible
issues or performance decline.
RAID members need to be included at the same enclosure that means
you need to create array in the same enclosure. RAID members across
two or more enclosures would get some risks (for example: if mini-SAS
cable get problem, more RAID members will be lost, volume sets belong
to this Array may be failed. Shutdown RAID and JBOD to fix problem,
after that, turn on JBOD and RAID system again and controller will get
array back, but in some special case maybe it can't get array back)
