IBM FlashSystem 5015 Storage Server

The IBM FlashSystem 5015 is a 2U rackmount storage server designed for enterprise workloads. It arrives with 12 x 2.4TB 10K SAS HDDs installed and a 64GB cache. Dual active controllers and redundant power supplies provide high availability.

Ideal For And Not For

Suits IT teams building a SAN with block access over 16Gb Fibre Channel or 1Gb iSCSI. VMware integration simplifies virtualised environments. Not suited for buyers who need hardware-assisted compression, data-at-rest encryption, or NVMe flash performance.

Deciding Specification

Maximum throughput reaches 8GB/s with latency under 70µs and up to 400K IOPS. Distributed RAID 1, 5 and 6 protect the 20TB raw capacity. Remote replication supports synchronous and asynchronous mirroring.

Questions about this item

How do I verify the 400K IOPs and sub-70µs latency after installation?

Run the built-in performance monitoring tools to confirm the system reports 400K IOPs and latency under 70µs during typical workloads.

Which drives and cables are included versus what I must purchase separately?

The unit ships with 12 x 2.4TB 10K SAS HDDs, 64GB cache, dual active controllers, 2 x 4-port 16Gb Fibre Channel cards and 8 x 5m OM3 LC cables; additional 2.5-inch flash drives, SFF 2.5-inch or LFF 3.5-inch drives must be bought separately.

Should I choose the 20TB configuration or a different capacity for my workload?

The 20TB model delivers 12 x 2.4TB SAS HDDs, 64GB cache and 400K IOPs; select it when you need that raw capacity and performance envelope, otherwise consider a lower-capacity variant if your dataset is smaller.
