IBM System Storage DS4800
 |
The IBM System Storage™ DS4800 disk storage system supports a high-performance 4 Gbps Fibre Channel interface. Increased host connectivity delivers the necessary bandwidth for high-throughput applications. Designed for data-intensive applications that demand increased connectivity, eight 4 Gbps host channels can help provide up to 1724 MBps of sustained bandwidth, allowing for high&45;throughput applications through eight channels directly attached to the host servers or connected to a Fibre Channel storage area network (SAN).

EXP3000
 |
The IBM System Storage EXP3000 is a high-density 2U, 19" rack-mountable driven closure designed for supporting a total of 12 Serial Attached SCSI (SAS) 3.5-inch disk drives.
The dual-port MegaRAID 8480 adapter is optimized for cost-sensitive and space-limited environments that demand both feature-rich and high-performance solutions. The adapter delivers an intelligent and robust RAID solution supporting RAID levels 0, 1, 10, 5, and 50, and utilizing a high-performance Intel I/O processor for optimum RAID performance and a PCI-Express host interface for increased bandwidth.
Together, the EXP3000 and MegaRAID 8480 leverage leading Serial-attached SCSI (SAS), the new interface technology with broad industry commitment and interoperability behind it. A maximum of four EXP3000s can be cascaded from the MegaRAID 8480 adapter to support a total of 48 disks while simultaneously improving performance of the configuration due to higher number of disks.
