An email from George (we will call him):

Hi Martin,

A bit of a silly question but do blade servers have RAID array controllers or do they use those notebook drives, one of the guys in the office was saying he didn’t think they do. There are rumors head office are going to be sending some down for testing and it would be nice to know what’s different.

Thanks

George”

My reply:

“Hi George,

Great to hear from you. Blade servers come in a range of types and specifications, to answer your question yes and no. Some of the earlier blade servers used notebook hard drives and didn’t always have an array controller but that was back in the IDE days. These days the blade servers tend to have array controllers and the discussion tends to be more about whether you require hot swap disks or not, the hot swap ones being SAS disks like the ones you have on your existing rack servers.

To know the array controller model and the type of disks installed we would need to know more about the type of blade and model, but yes it will typically have a RAID controller.

Regards

 

Martin”
