IBM FlashSystem 5015 Storage Server

This 2U rackmount storage server delivers 40TB of raw capacity using 14 pre-installed 3.84TB SAS SSDs. Dual active-active controllers provide 64GB of cache and redundant hot-swappable power supplies and fans. It targets organisations that need block storage with VMware and Red Hat OpenShift integration.

Upgrade From Older Arrays

The system replaces legacy disk-based arrays when applications demand sustained 400K IOPs and sub-70µs latency. The jump is worth it for workloads that can exploit hardware-assisted Easy Tier automated tiering and synchronous or asynchronous remote replication. Buyers who require built-in hardware compression, encryption or NVMe flash support will not find those features here.

16Gb Fibre Channel And 12Gb SAS Limits

Host connectivity tops out at 16Gb Fibre Channel and 12Gb SAS, capping maximum bandwidth at 8GB/s. The 1Gb and 10Gb iSCSI ports share the same back-end controllers, so mixed protocol deployments contend for the same 400K IOPs ceiling. Clusters that need NVMe-over-Fabrics or higher single-stream throughput must look beyond this platform.

Questions about this item

What rack depth and clearance does the 2U FlashSystem 5015 chassis require for the hot-swappable fans and dual power supplies?

The unit is a 2U rackmount design with fully redundant, hot-swappable fans and power supplies; allow front-to-rear airflow space for cooling.

Which cables and host ports must be connected during initial setup of the dual active controllers and 16Gb fibre cards?

Connect the eight supplied 5m OM3 LC fibre cables to the 2 x 4-port 16Gb fibre cards and link the onboard 1Gb iSCSI ports; both controllers are active/active so cable each for full redundancy.

When do the 14 x 3.84TB SAS SSDs or the 64GB cache modules need replacement in the FlashSystem 5015?

The 14 SAS SSDs are hot-swappable for drive replacement; the 64GB cache is part of the dual controller modules, which are also hot-swappable for service.
