7.3 Hard Drive Type

JBOD2000S3SP can support 12Gb/s, 6Gb/s, and 3Gb/s SAS hard drives and 3Gb/s and 6Gb/s SATA hard

drives. SATA hard drives do not support some configurations, which need to take advantage of the dual-port

SAS hard drives, such as dual-domain SAS or failover clustering.

JBOD cascading is also called daisy-chaining, which means connecting multiple JBOD units to constitute

deeper storage pool. How many JBOD2000S3SP can be cascaded depends on the property of the SAS HBA

or RAID adapter that connects to JBOD2000SP3. However, only two layers of cascaded JBOD2000S3SP

system have been fully validated by Intel. Only cascading the same type of JBOD2000S3SP is

recommended.

The following sections provide the external connection modes supported by the Intel

Storage System

JBOD2000S3SP single-port backplane SKU.

7.5.1

Figure 27 below shows the SAS HBA or RAID adapter connecting to one single-port JBOD2000S3SP with

one mini-SAS HD cable. The single controller port incorporates four SAS lanes for a total maximum

throughput of 4800MB/s with SAS 3.0 technology. In the figure, the "4\" notation indicates a 4-lane bundled

path. Either A PRI or B PRI SAS port on JBOD2000S3SP can be connected in this scenario. SATA or SAS hard

drives can be supported.
