Cisco UCS C Series Rack Servers - Refurbished, Used, New
Cisco UCS C-Series rack servers are standalone 1RU and 2RU x86 servers that run on their own or under UCS Manager and Intersight alongside B-Series blades. The C220 is the 1RU general-purpose box and the C240 the 2RU storage-heavy box, across M3, M4 and M5 generations, with older C200, C250, C260 and C460 parts still in service. NetworkTigers sells C-Series chassis, power supplies, rail kits, RAID controllers, NVMe drives, fans, network adapters and the small parts that keep a server in production, refurbished, used and new. Every server and part is tested before it ships so it works when it arrives.

Which UCS C-Series do I need?
Settle the generation first, because almost nothing crosses it: M3, M4 and M5 use different CPUs, memory, RAID controllers, rails and power supplies, and a part for one will not fit the next. If you are adding to an existing UCS domain, buy the generation your firmware already supports. Then choose 1RU or 2RU: a C220 gives two sockets and a handful of drives in 1RU; a C240 gives the same compute with up to 24 small form factor or 12 large form factor bays and more PCIe slots. Pick the drive form factor to match the backplane, since an L chassis takes 3.5-inch drives and an S or SX chassis takes 2.5-inch, and NVMe bays only take NVMe. For power, fit two supplies of the same part number, sized for the CPUs, drives and any GPU you install. Send us the serial or the show inventory of the server you are matching and we will confirm the part fits.
Frequently asked questions
Can I run a C-Series server without Fabric Interconnects?
Yes. Every C-Series rack server runs standalone through its CIMC management port with a web interface and a KVM console. Fabric Interconnects and UCS Manager only come into play when you want the server managed as part of a UCS domain with the blades.
Do the servers ship with drives and memory?
Only when the listing says so. Many of our C240 M5L listings include a pair of CPUs; drives, memory and RAID cache are listed separately so you can build to your own spec. Ask us for a configured quote if you want a complete system.
What is a flash-backed write cache and do I need it?
The 1GB cache module on the 12G SAS controller holds write data until it is committed to disk and keeps it safe through a power loss. You want it for any RAID 5 or RAID 6 volume that takes writes; for RAID 0 or 1 boot volumes it matters less.
NetworkTigers has sold enterprise network equipment since 1996. Every server and part carries the NetworkTigers 365-day warranty. Need a quantity? Ask us for a quote.
