Storage Capacity and Form Factor

The IBM FlashSystem 5300 is a 1U rackmount barebones server designed as an all-flash storage platform. It ships with eight 4.8TB FlashCore Modules delivering 45TB effective capacity at 2:1 compression. A 256GB cache and distributed RAID 1, 5 and 6 protect data. NVMe flash and FC-NVMe host connections provide low-latency access for storage workloads.

Target Workloads and Limitations

This system suits organisations needing high-performance SAN storage with inline data reduction, encryption and VMware integration. Features such as Safeguarded Copy, CyberVault support, Hyperswap and remote replication address cyber-resiliency and high-availability requirements. It is not for buyers who require direct-attached block storage without a fibre-channel or iSCSI fabric, or teams lacking rack space and SAN networking expertise.

Deciding Specification

The host connectivity mix of 25/10Gb iSCSI and 32Gb Fibre Channel dictates whether the array fits your existing fabric. Two four-port 32Gb fibre cards and eight 5m OM3 LC cables are included for immediate SAN attachment. If your infrastructure uses only Ethernet speeds not listed here, or requires 64Gb Fibre Channel without the installed cards, this unit will not connect without additional hardware.

Questions about this item

What rack width does the 1U FlashSystem 5300 fit?

The 1U chassis mounts in a standard four-post rack; sliding rails are included with the barebones unit.

Which cables connect the 32Gb Fibre Channel ports during first setup?

Eight 5-metre OM3 LC cables are supplied; plug them into the two 4-port 32Gb cards before powering on.

When do the 4.8TB FlashCore Modules need replacement?

Modules are rated for the system’s endurance limit; monitor wear via IBM Storage Insights Pro and swap only when the dashboard flags a module.
