While many storage managers and administrators continue to be the primary drivers into storage area networks and finding the best fit for their storage networks, we are starting to see some security network administrators give their “2 cents” when it comes to selecting a storage area network, whether it’s a Dell EqualLogic or a Dell Compellent SAN. “Why?” you might ask…? Aside from sheer boredom, more storage arrays are now shipping with self-encrypting drives, sometimes called SED drives.
How are these different from your standard NL-SAS, SAS, and / or SSD drives I might already finding on EqualLogic pricing or Compellent pricing…? Well, they’re really not…but essentially these self-encrypting drives are being built with a circuit that comes embedded into the disk drive controller chip.
What this essentially does is encrypt and decrypt the data that is put onto the magnetic media without any human intervention. In fact, the SED drives come factory-default on many HDD and SSD drives.
There’s really a lot more detail that goes into the SED drives such as password creation, etc., but we’re not going to bore you with all the finite details here. What’s important to note is that SED drives are relevant in preventing data loss while performance is not impacted. So next time you seek EqualLogic pricing or Compellent pricing on a Dell storage solution, ask if the drives have SED…the price is a bit more, but it could be worth it…
