Hello,
We have worked with Rorke Data for years and they have several options for building SAN’s. Their ability to match the technology with individual workflow requirements will be extremely helpful to you weeding through your options. Rorke also has a new product out called the Aurora, very high performance with the ability to plug up to 8 editing systems to one Raid with out a switch at a very attractive cost per GB.
What’s just as important is that Rorke’s tech support folks know their stuff. If you need help, they know the answers.
You can find them at https://www.rorkedata.com
Good luck in your search
