70 TB NL-SAS storage server

The IBM FlashSystem 5045 is a 2U rackmount barebone server built around twelve 8 TB 7.2K NL-SAS hard drives that deliver 70 TB of raw capacity. It ships with 64 GB of cache and includes dual 16 Gb Fibre Channel adapters plus 10 Gb iSCSI connectivity for host access. This platform targets organisations that need a dense, entry-level storage array for backup, archive or secondary workloads. Redundant hot-swap fans and power supplies keep the chassis running during component replacement.

Suited for capacity-first deployments.

Teams that prioritise cost per terabyte and can tolerate 7.2K rotational latency will fit this system into existing SAN fabrics through 1 Gb iSCSI or 16 Gb FC links. VMware integration, data reduction pools and Safeguarded Copy simplify management for virtualised environments. Buyers who require sub-millisecond latency, NVMe flash media or hardware-accelerated compression should evaluate all-flash alternatives instead.

1.2 M IOPS peak with distributed RAID

The headline performance figure is 1.2 million IOPS delivered through distributed RAID 1, 5 and 6 across the twelve drive slots. Minimum latency is quoted under 70 µs and maximum bandwidth reaches 12 GB/s when the cache and host links are saturated. This IOPS ceiling determines whether the array can sustain your mixed read/write workload without adding flash tiers.

Questions about this item

At what point do the 12 NL-SAS drives hit their 1.2M IOPs ceiling during sustained workloads?

The array reaches its 1.2M IOPs limit when the 12 x 8TB 7.2K NL-SAS drives and 64GB cache can no longer absorb random read/write pressure, typically under heavy OLTP or analytics streams.

How much heat and fan noise should I expect from the 2U chassis when the 12 drives and dual power supplies run continuously?

Fully redundant, hot-swappable fans and power supplies keep the 2U enclosure within spec, but sustained 7.2K drive activity and 16Gb Fibre Channel traffic will raise exhaust temperatures and fan speeds noticeably.

Which host-side HBAs and cables are needed to use the onboard 10Gb iSCSI and 16Gb Fibre Channel ports?

You must provide 10GbE SFP+ or 16Gb Fibre Channel HBAs plus matching OM3 LC cables; the unit includes 8 x 5m OM3 fibres for the FC links.
