Product Introduction
This hardware manual briefly introduces the EonStor SAS-to-SAS
(Serial Attached SCSI) RAID enclosure that houses either SAS or
Serial ATA (3Gbps SATA-II) disk drives. The enclosure comes with
the host-side connectivity via 4x wide SAS connectors and supports
twelve (12) hot-swappable SAS/SATA disk drives. The enclosure is

enclosure, along with SAS JBODs, connects to application servers
and serves as a building block of a scalable configuration.
The RAID firmware supports communications with SAS initiators and
SAS or SATA disk drives. In terms of physical connection, the SAS
interface provides ease of cabling through SFF-8088, 4x wide, mini-
SAS interface connectors. Each SAS channel within is capable of a
1.5/3.0Gb/s data rate. Each RAID controller provides two (2) SAS
connectors for host and one (1) SAS connector for expansion each
with 4 PHYs. With a SAS-/SATA-compatible backplane, the
subsystem supports SAS or 3Gbps SATA-II disk drives, and is ideal
for adding large capacity to a storage pool.
Dual-redundant RAID controllers (S12S-R1032), power supplies and
cooling modules protect the subsystem from the down time caused
by single module failure. Power supply units (PSU) share load in a
dual-redundant configuration, and is able to sustain system operation
