Frequently asked questions

What does the warranty cover?

Our warranty covers all hardware faults, but please note it doesn’t cover accidental damage or software issues. However, we’re here to help with technical support for those matters!

What is a refurbished device?

A refurbished device is a pre-owned item that has been restored to meet high-quality standards. At Reboot IT, we adhere to strict quality guidelines, ensuring that our refurbished products are not the same as used or secondhand items. We meticulously clean, test, and assess each device, replacing worn parts with high-quality components.

Unlike used items, which lack guarantees and rely solely on the seller's word regarding condition, refurbished devices come with assurance of quality and reliability.

What payment options are available?

We offer a variety of payment options to make your shopping experience as convenient as possible! You can pay using all major credit cards, Apple Pay, Google Pay, Shop Pay, Afterpay, Zip Pay, and PayPal. If you prefer, we also accept bank deposits and even cash for in-store purchases!

Description

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.

All-in-one Solution for Home Office

I was looking for an in-expensive all-in-one solution for my home office to replace my existing desktop and monitor. I found this EliteOne 800 on reboot IT for under $200. I wasn't sure what to expect. It arrived within two days!!!! I upgraded the RAM, replaced the HDD and installed Windows 11. This is unbeatable value and was the cheapest price online. Coupled with a 3-month warranty, Reboot IT are by far the best online refurbished retailer I have used. Awesome!

Fair tech for price

Fair tech for price, good specs for era, serves the purpose. The black keyboard is an interesting rubber like texture clearly by design to pad the screen and avoid the keyboard touching. Screen is great. Still looking for magic formula to enable computer use in the bright bright sunshine. Keyboard taps are loud for someone who likes silent touch. The perfect PC has to exist, like build a bear.

Works excellently as advertised.

The laptop was sold with a warning about worn keycaps. In fact they had been obviously vandalised (ex school laptops, perhaps?). The keyboard worked fine, and the rest of the laptop too. I'm using it as a file server, so I don't need the keyboard much. So very pleased, and also pleased with reboot-it's service - as always, excellent, and quick responses to any queries.
