IBM FlashSystem 5300 18TB Storage Server

This IBM FlashSystem 5300 is a 1U rackmount storage server built around 18TB of usable capacity from two 9.6TB FlashCore Modules. It delivers 256GB cache, hardware compression and deduplication, encryption, VMware integration and Safeguarded Copy for cyber resilience. Designed for high-performance block workloads.

Who this suits and who should look elsewhere

Ideal for teams needing sub-50µs latency, 2.2M IOPS and 28.6 GB/s bandwidth over 25Gb iSCSI or 32Gb Fibre Channel with FC-NVMe. Not suited for buyers who require file or object protocols, direct-attached GPU compute, or a smaller rack footprint than 1U.

Deciding specification: 9.6TB FlashCore Modules

The two 9.6TB FlashCore Modules provide the 18TB effective capacity at 2:1 compression and the patented NVMe flash architecture that drives the latency and IOPS figures. Confirm the raw 19TB capacity and drive count match your RAID and expansion plans before ordering.

Questions about this item

How does the 256GB cache perform under sustained heavy I/O workloads?

The 256GB cache works with hardware-assisted compression and Distributed RAID to sustain high throughput. The system delivers up to 2.2M IOPs with latency under 50µs and maximum bandwidth of 28.6 GB/s.

What are the thermal and acoustic characteristics when the 1U rackmount unit runs continuously?

The 1U form factor houses 2 x 9.6TB FlashCore Modules and dual 4-port 32Gb Fibre Channel cards. It supports 2.5-inch flash drives, SFF 2.5-inch and LFF 3.5-inch disk drives for flexible deployment.

Which host connectivity infrastructure must already be in place to use the onboard 25/10Gb iSCSI and 32Gb Fibre Channel ports?

The system provides onboard 25/10Gb iSCSI and 2 x 4-port 32Gb Fibre Channel cards. It also supports 10Gb iSCSI and 32/64Gb Fibre Channel connectivity for existing SAN and Ethernet fabrics.
