2U All-Flash Storage Server

The IBM FlashSystem 7300 is a 2U rackmount storage server built around 24 FlashCore Module 4 drives. It targets enterprises that need high-density, low-latency block storage for virtualised workloads and databases. Hardware-assisted compression, deduplication and encryption are integrated into the controller.

460 TB Raw and 765 TB Effective Capacity

Raw capacity sits at 460 TB across the 24 modules, while usable capacity after distributed RAID is 383 TB. With the onboard 2:1 compression engine the effective capacity reaches 765 TB, backed by 756 GB of cache. Workloads that compress well stay within this headroom; incompressible data will hit the 383 TB usable limit.

32 Gb Fibre Channel and 100 Gb Ethernet Connectivity

Host connections include four 4-port 32 Gb Fibre Channel cards and 10/25/100 Gb Ethernet for iSCSI and NVMe RDMA. The system sustains up to 3.5 million IOPS and 45 GB/s bandwidth with latency under 50 µs. Environments that require higher throughput or lower latency than these figures provide will need a larger array.

Questions about this item

Will the 32Gb Fibre Channel host connections work with my existing 16Gb HBAs?

The 32Gb Fibre Channel ports auto-negotiate down to 16Gb speeds, so current 16Gb HBAs and cables will operate normally at their rated throughput.

How can I confirm the 756GB cache and 24 FlashCore Modules are active after installation?

The management GUI reports cache utilisation and enumerates all 24 FCM4 modules with health status; latency should sit under 50µs during normal I/O.

Which cables and drives are included, and what must I source separately?

The shipment contains 16 OM3 LC fibre cables for the 32Gb FC ports; the 24 x 19.2TB FlashCore Modules are pre-installed. No additional drives are required for the 765TB effective capacity.
