IBM System x3550 M4 1U Rack Server Xeon E5-2620v2 6-Core 8GB 600GB SAS | Wty

IBM System x3550 M4

Key Benefits

• Dual Xeon E5-2600 v2 in 1U — up to 24 cores (48 with HT) in a single rack unit — exceptional compute density for virtualisation and parallel processing workloads
• Up to 768 GB DDR3 ECC — substantial memory capacity in a 1U chassis — rarely available without a 2U or larger platform in older generations
• IBM IMM2 management — out-of-band remote management with KVM console, virtual media, power control, and hardware health monitoring independent of the OS
• Hot-swap drive bays — replace failed drives without shutdown — essential for production storage environments with uptime requirements
• IBM ServeRAID support — hardware RAID with battery-backed write cache for protected SAS/SATA array operation
• 1U compact chassis — maximise server count per rack — useful for high-density compute clusters, lab racks, or co-location with limited rack space

Performance in Use

The IBM System x3550 M4 represents the engineering balance IBM achieved in compact server design: fitting dual-socket Xeon E5-2600 v2 performance and 24 DIMM slots into a 1U chassis without compromising on expandability or manageability. For datacentres counting rack units and kilowatts carefully, the x3550 M4 delivers meaningful compute density at its size.

IMM2 remote management is a mature out-of-band platform offering KVM-over-IP console redirection, virtual media mounting, and REST API access for infrastructure automation. For managed service providers and datacentre teams, standardised IMM2 management means the x3550 M4 integrates into existing remote management workflows with minimal adjustment.

Frequently Asked Questions

What CPUs are compatible with the x3550 M4?

The x3550 M4 supports Intel Xeon E5-2600 v1 (Sandy Bridge-EP) and E5-2600 v2 (Ivy Bridge-EP) processors. IBM's ServerProven compatibility guide lists validated models.

Does it support VMware ESXi?

Yes — the x3550 M4 is VMware ESXi certified for versions 5.x and 6.x. ESXi 6.7 support depends on specific CPU and NIC configurations.

How is the IMM2 accessed?

IMM2 has a dedicated management Ethernet port (or shares a data port in shared mode). It is accessed via web browser or IBM's Systems Director/IBM Director management software.

Can I add a GPU or PCIe accelerator?

The 1U chassis limits PCIe slot depth and height. Full-height double-width GPUs are not compatible. Low-profile PCIe cards fit the available expansion slots.

What shipping costs apply?

Shipping costs apply based on size and destination — rates are calculated at checkout.
