Solution Elements:
Server
8-port SAS RAID HBA for 4800MB/s total bandwidth
RAID levels 0, 1, 5, 6, 10, 50
JBOD enclosure that can be daisy-chained to additional arrays to increase capacity
Cable redundancy due to dual connectors and dual controllers in the external enclosures
Internal four-drive 5.25” chassis
3. High-Performance SAS Server Clusters
Application: Reduced-cost failover without performance loss
This solution provides an alternative to clustered Fibre Channel local loop topologies —
high performance and high availability with no single point of failure. It can be
implemented using a SAS ASIC (mounted on the motherboard) or SAS RAID HBA. The
hosts share a storage pool on the SAS JBOD enclosure, which supports either SAS or
SATA drives. The storage pool can be easily scaled with the addition of more disks or
extra JBODs. Dual controllers with multi-path I/O support and RAID 6 provide the
highest availability, even with low-cost SATA drives.
Ideal for applications including:
• High-performance enterprise cluster configurations
• Business-critical primary storage
• Data warehousing
• Video and audio streaming
