All-Flash Storage Server for Enterprise Workloads

The IBM FlashSystem 5045 delivers 30TB of raw capacity in a 2U rackmount chassis populated with twelve 3.84TB SAS SSDs. It provides 64GB of system cache and dual-host connectivity through 10Gb iSCSI and 16Gb Fibre Channel. The platform targets storage servers that require consistent sub-70µs latency and up to 1.2M IOPs for databases, virtualisation and containerised applications.

Upgrade Path from Hybrid or Spinning-Disk Arrays

This system replaces environments where mechanical drives or mixed media cannot sustain the throughput or latency targets of modern workloads. The jump is justified when applications demand sustained 12GB/s bandwidth, inline data reduction through compression and deduplication, and enterprise features such as encryption, Safeguarded Copy and Hyperswap high availability without adding separate hardware.

Rackmount Installation

The 2U form factor fits standard racks and ships with fully redundant, hot-swappable fans and power supplies to simplify deployment and ongoing maintenance. Eight 5m OM3 fibre cables with LC connectors are included for immediate Fibre Channel connectivity. Care is required to verify that the host infrastructure supports 16Gb Fibre Channel or 10Gb iSCSI, and that the 2.5-inch drive bays match the replacement media strategy.

Questions about this item

What rack space and drive bay layout does the 2U FlashSystem 5045 require?

The unit occupies 2U of rack height and ships with 12 front-accessible 2.5-inch bays populated by 3.84TB SAS SSDs.

How are the 16Gb Fibre Channel adapters and 10Gb iSCSI ports connected during initial setup?

Insert the supplied 5m OM3 LC cables into the onboard FC ports and plug the RJ-45 or SFP+ links into the 10Gb iSCSI interfaces; the step often missed is enabling the FC target ports in the management GUI before zoning.

Which components will need replacement over the system's life?

The hot-swappable fans, redundant power supplies and the 3.84TB SAS SSDs are the field-replaceable parts; cache memory and controller boards are not user-serviceable.
