IBM FlashSystem 5045 15TB Storage Server

The IBM FlashSystem 5045 is a 2U rackmount storage server delivering 15TB of raw capacity across twelve 1.92TB SAS SSDs. It provides 64GB of cache and supports 10Gb iSCSI and 16Gb Fibre Channel host connections. Designed for enterprise storage workloads, it includes data reduction pools with compression and deduplication.

Suits high-IOPS block workloads; not for NVMe flash

This system suits environments needing up to 1.2M IOPS with sub-70µs latency and 12GB/s bandwidth. It supports VMware integration, Safeguarded Copy and Hyperswap high availability. Buyers requiring NVMe flash media or FC-NVMe host connections should evaluate alternative platforms that support those protocols.

15TB SAS SSD capacity with 12 drive bays

The defining specification is the 15TB usable capacity configured as twelve 1.92TB SAS SSDs in a 2U form factor. This drive count and media type determine the density, performance ceiling and expansion options for the array. Verify that SAS SSD media and the 2.5-inch bay count align with your capacity and protocol requirements.

Highlights

  • 15 TB raw flash capacity from 12 x 1.92 TB SAS SSDs
  • 64 GB cache accelerates read and write performance
  • 2 million IOPS with latency under 70 µs
  • Data reduction pools provide compression, deduplication and thin provisioning
  • Redundant hot-swappable fans and power supplies maintain uptime

Questions about this item

How do I verify the 1.2M IOPs and under 70µs latency after installing the 5045?

Run storage benchmarks against the 12 x 1.92TB SAS SSD array; sustained reads should approach 1.2M IOPs with latency consistently below 70µs when Data Reduction Pools are active.

What ships with the 2U 5045 barebone and what must I source separately?

The unit includes 12 x 1.92TB SAS SSDs, 64GB cache, dual 16Gb Fibre Channel adapters, onboard 10Gb iSCSI, redundant hot-swap power supplies and fans, plus 8 x 5m OM3 LC fiber cables; rack rails and host HBAs are not included.

Which 5045 capacity configuration matches a 15TB raw requirement?

The listed model provides exactly 15TB raw via 12 x 1.92TB SAS SSDs; no other capacity variant is described in the specifications.
