All RAID systems provide a range of redundancy features that include all RAID levels RAID 0, 1 (0+1), 3, 5, 6, 10, 30, 50, NRAID and JBOD. Redundant hot swap fans, power supplies, hard disks. Some of the RAID systems also feature redundant dual controller cards with hot swap, 72 hour cache memory backup.
Multi host attach support is standard and depending on the model and configuration up to 12 fibre channel hosts can be connected to a single RAID system. Alternatively you can connect the systems to a storage server and use iSCSI to serve up disk space.
RAID management is done through an intuitive GUI and shows detailed information relating to the status, configuration and reporting features.
Our SCSI RAID systems combine cost effective pricing and high capacity against SAS or Fibre Channel disk based RAID systems.
Our extensive range of disk storage systems, comprise of various host attachments including fibre channel via direct point-to-point or through a fibre channel switch, direct attached SAS / SCSI using a SAS / SCSI controller card, iSCSI network attached through software or hardware. All models use the latest disk drives including 15,000 rpm SCSI and fibre channel disks as well as Serial ATA 7,200 rpm and 10,000 rpm drives.
Our RAID systems support 99.9% of all operating systems currently in existence including all flavours of Windows, Linux, Novell and UNIX. We can also supply the SCSI RAID systems with different host attach cabling for connecting to legacy SCSI controllers.
SCSI RAID are ideal for attaching to older generation systems with SCSI controllers.
SCSI RAID Systems are increasingly being replaced by SAS RAID, these offer many benefits over SCSI including easier cabling, better performance and can support Active/Active controllers.
