Blades vs Standard Servers

You are here: Home » Hardware » Blades vs Standard Servers

When it’s time to decide on a heavy investment like this it’s not uncommon to look before you leap. There are advantages and disadvantages of both. Lets take a look.

Advantages to Blades
  • Density – You can pack a lot of serves in a rack with blades.
  • Power – Blades cost a lot less in electricity then standard servers.
  • Less expensive per socket – The more blades you need the cheaper per socket they are.
  • Clustering – They’re fantastic in vSphere/XenServer clusters. Much better hardware and driver support.
  • Remote Management – It’s fantastic being able to boot into the BIOS of a blade from 1000 miles away.

Disadvantages to Blades
  • Less expensive entry cost – The chassis alone can cost a lot. Then you need storage, and if you go fibre you need fibre switches. It adds up if you don’t go with iSCSI or NFS.
  • Easier to upgrade – Some blades are easier than others but we are all used to simple tasks like adding RAM or a hard drive.
  • Upgrades – If you really need to install a DAT24 tape drive you can.
  • Vendor Lock In – Once you go with a brand you usually have to stick with that brand and even the chassis type to help reduce costs.
