It supports up to four tiers and 122 SAS/SATAII peripheral devices (SAS/SATA
HDDs + Raid Enclosures) by using SAS expanders.
One Volume Set supports up to 32 HDDs
One SAS Raid subsystem supports up to 128 Volumes
One SAS Raid subsystem supports up to 122 SAS/SATAII peripheral devices
(SAS/SATA HDDs + Raid Enclosures) by using SAS expanders.
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 Mini SAS to Mini SAS 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 Mini SAS to
Mini SAS 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 Mini SAS to Mini SAS Cable.
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.
