Flash is everywhere these days and everyone likes to throw out impressive performance numbers. If someone told you that flash is faster than a hard drive I am sure the thought that pops into your head is, “yeah… thanks for the info”. Nothing shocking about the statement, the real question is what do you do with this resource? Most vendors are using roughly the same NAND with slight variations. How does the implementation take full advantage of the most expensive part of the solution?
One Giant Pool of Flash
Nutanix is a converged distributed storage system made up of many nodes. Each node supplies locally direct attached flash and hard drives. It’s the local virtual storage controller running on each node that takes all of the resources and puts them into one storage pool.
