ARC-8306
(1Gb/s iSCSI-to-SAS Redundant Controller)
|
The 6Gb/s iSCSI to SAS RAID controllers attach directly to SATA/SAS
midplanes with 3 x Z-PACK HM-Zd high speed connectors or
increase capacity using one additional SFF-8088 external
connector. When used with SAS expanders, the controller can
provide up to (122) devices through one or more SAS JBODs,
making it an ideal solution for enterprise-class storage
applications that called for maximum configuration flexibility.
The Fibre/SAS/iSCSI to 6Gb/s SAS RAID subsystem provides three
kinds of host interface link to the host board on the server
system. This subsystem utilizes the same RAID kernel that has
been field-proven in existing internal/external SATA/SAS RAID
controller products, allowing to bring stable and reliable SAS
RAID external subsystem. |
