See the Dot Hill web site for more information about specific storage product models and uses: http://www.dothill.com. AssuredSAN 3004 Series enclosures support both traditional linear storage and new virtual storage, which uses paged-storage technology. For linear storage, a group of disks with an assigned RAID level is called a vdisk or linear disk group. -

CompactFlash, you must transport the CompactFlash from the failed controller to the replacement controller using a procedure outlined in AssuredSAN 3004 Series FRU Installation and Replacement Guide within the procedure for replacing a controller module. Failure to use this procedure will result in the loss of data stored in the cache module. -
Page 18: Supercapacitor Pack
Supercapacitor pack To protect controller module cache in case of power failure, each controller enclosure model is equipped with supercapacitor technology, in conjunction with CompactFlash memory, built into each controller module to provide extended cache memory backup time. The supercapacitor pack provides energy for backing up unwritten data in the write cache to the CompactFlash, in the event of a power failure. -

AssuredSAN 3004 Series controller modules support both 3-Gbps and 6-Gbps internal disk drive speeds together with 3-Gbps and 6-Gbps expander link speeds. CAUTION: Some 6-Gbps disks might not consistently support a 6-Gbps transfer rate. If this happens, the system automatically adjusts transfers to those disks to 3 Gbps, increasing reliability and reducing error messages with little impact on system performance. -

Page 28: Connecting Hosts
Connecting hosts Host system requirements Hosts connected to an AssuredSAN 3004 Series controller enclosure must meet the following requirements: • Depending on your system configuration, host operating systems may require that multipathing is supported. If fault tolerance is required, then multipathing software may be required. Host-based multipath software should be used in any configuration where two logical paths between the host and any storage volume may exist at the same time. -
