Crain needs to do better research on his competitors. Hot swap is one of Violin's key features.
Two venture capital firms have pumped A-round initial funding cash into flash array start-up Whiptail. What's got them so fired up? Whiptail's XLR8r appliance is an all-flash memory array that can store things like VDI images and pump them out to booting PCs faster than a disk drive array. Whiptail CEO Dan Crain said: "We're …

WhipTail is architected in a familiar manner - drives in the front, plugs in the back. On the front of the array it is simple to unlock the front bezel and see the 24 drive slots that can be populated with anywhere from 1.5TB to 12TB of hot-swappable MLC based drives that can be replaced, upgraded online, etc.. Access is easy and natural.

That's like saying a human kidney is hot-swappable. Technically true, you don't have to stop the heart and resurrect the patient to get the job done, but it's not as hot-swappable as, say, a pair of shoes.
