򐂰 IBM System Storage DS5100 server
The DS5100 is targeted at high-end customers. This storage subsystem is a 4U
rack-mountable enclosure, has sixteen 4 Gbps FC drive interfaces, and can hold a
maximum of twenty-eight EXP5000 expansion units, a maximum of twenty-eight EXP810
expansion units or, for migration purposes, up to twenty-eight expansion units composed
of a mix of EXP5000 and EXP810 for a total of up to 448 disk drives.
The DS5100 can have up to 32 GB of cache memory and different host connectivity
options as listed below:
– Four 4 Gbps FC host ports on each of its two controllers
– Four 8 Gbps FC host ports on each of its two controllers
– Two 1 Gbps iSCSI host ports on each of its two controllers
– Eight 4 Gbps FC host ports on each of its two controllers
– Eight 8 Gbps FC host ports on each of its two controllers
– Four 8 Gbps FC host ports and Two 1 Gbps iSCSI host ports on each of its two
controllers (waiting for DST)
– Four 1 Gbps iSCSI host ports on each of its two controllers
At the time of writing one model is available:
– Model 51A with 8 GB, 16 GB, or 32 GB of cache memory and one of the combinations
of host interfaces specified in the list above.
򐂰 IBM System Storage DS5300 server
The DS5300 server has greater scalability than the DS5100. This storage subsystem is a
4U rack-mountable enclosure, has sixteen 4 Gbps FC drive interfaces, and can hold a
maximum of twenty-eight EXP5000 expansion units, a maximum of twenty-eight EXP810
expansion units, or, for migration purposes, up to twenty-eight expansion units composed
of a mix of EXP5000 and EXP810 for a total of up to 448 disk drives. It is designed to
deliver data throughput of up to 400 MBps per drive port.
The DS5300 can mount up to 64 GB of cache memory and different host connectivity
options as listed below:
– Four 4 Gbps FC host ports on each of its two controllers
– Four 8 Gbps FC host ports on each of its two controllers
– Four 1 Gbps iSCSI host ports on each of its two controllers
– Eight 4 Gbps FC host ports on each of its two controllers
– Eight 8 Gbps FC host ports on each of its two controllers
– Four 8 Gbps FC host ports and four 1 Gbps iSCSI host ports on each of its two
controllers
– Eight 1 Gbps iSCSI host ports on each of its two controllers
One model is available:
– Model 53A with 8 GB, 16 GB, 32 GB, or 64 GB of cache memory and one of the
combinations of host interfaces specified in the list above.
