All-flash storage server for enterprise workloads

The IBM FlashSystem 5300 170TB is a 1U rackmount storage server built for high-density flash deployments. It targets organisations that need consistent low-latency access to large datasets in a compact form factor. The system ships with 12 FlashCore Modules delivering 9.6TB each. It is not for buyers who require 3.5-inch mechanical drive support in the primary bays.

Rack space and host connectivity checks

Verify that your rack provides a single 1U slot with adequate airflow for a dense flash array. Confirm your host infrastructure can use 25/10Gb iSCSI or 32Gb Fibre Channel connections, as these are the onboard host interfaces. The unit includes eight 5m OM3 fibre cables with LC connectors. Ensure your switch ports and HBA firmware support the required link speeds.

Sustained throughput and data reduction behaviour

Under sustained load the array delivers up to 2.2M IOPS with minimum latency under 50µs and maximum bandwidth of 28.6 GB/s. Hardware-based compression and deduplication run continuously without CPU overhead. Distributed RAID 1, 5 and 6 maintain performance during rebuilds. CyberVault and Safeguarded Copy operations run in the background without impacting foreground I/O.

Questions about this item

What comes in the box and what must be purchased separately?

The system ships with 12 x 9.6TB FlashCore Module 4 drives, 2 x 4-port 32Gb Fibre Channel cards and 8 x 5m OM3 fibre cables (LC). Host cabling beyond the supplied OM3 fibres and any additional FlashCore Modules for expansion must be purchased separately.

Which capacity version should I choose if I need the 170TB effective figure?

The 170TB effective capacity assumes 2:1 compression on the 12 x 9.6TB FlashCore Modules. Choose this configuration when your workload benefits from hardware-assisted compression and deduplication; raw capacity is lower without data reduction.

What does the 2.2M IOPS figure mean once the array is in production?

2.2M IOPS is the maximum sustained performance with under 50µs latency and up to 28.6 GB/s bandwidth, delivered by the NVMe FlashCore Modules and 256GB cache across Distributed RAID 1, 5 or 6.
