IBM FlashSystem 7300 170TB Storage Server

The IBM FlashSystem 7300 is a 2U rackmount all-flash storage server delivering 170TB effective capacity with 2:1 compression. It targets enterprises needing high-performance block storage for virtualised workloads and databases. Twelve 9.6TB FlashCore Modules provide the raw 115TB capacity behind the 85TB usable figure.

Host Connectivity and Rack Requirements

Verify your infrastructure supports 32Gb Fibre Channel or 10Gb iSCSI host connections before ordering. The system includes four 4-port 32Gb Fibre Channel cards and sixteen 5m OM3 fibre cables with LC connectors. Ensure the rack provides 2U space and compatible power and cooling for a dense storage platform.

Sustained Load Behaviour

Under sustained load the array delivers up to 3.5M IOPS with minimum latency under 50µs and maximum bandwidth of 45 GB/s. Hardware-assisted compression and Data Reduction Pools maintain throughput efficiency during continuous write-heavy operations. Distributed RAID 1, 5 and 6 protect data without a dedicated parity drive bottleneck.

Questions about this item

What ships with the FlashSystem 7300 and what must be purchased separately?

The unit includes 12 x 9.6TB FlashCore Module 4 drives, 756GB cache, four 4-port 32Gb Fibre Channel cards and 16 x 5m OM3 fibre cables. Host cabling beyond the supplied OM3 leads and any additional drives or expansion enclosures are bought separately.

Which capacity figure should I use when planning usable space — 115TB raw, 85TB usable or 170TB effective?

Use 85TB usable capacity for planning; 115TB is the raw total of the 12 modules and 170TB assumes a 2:1 compression ratio that varies with workload.

What does the 3.5M IOPs headline mean for a typical database workload?

3.5M IOPs is the maximum measured under ideal conditions; real-world database performance will be lower and depends on queue depth, block size and the mix of read and write operations.
