We are moving to using a lot of NFS (Network File System). I normally work with VMware on the private cloud and then I use NetApp on NFS protocol with 10G connectivity.
Mainly I use it in two ways. I use a lot of hybrid flash storage. Hybrid meaning that you have a little bit of SSD (Solid State Drive) and then at the back, you can use either SATA (Serial ATA [Advanced Technology Attachment]) or SAS (Serial Attached SCSI [Small Computer System Interface]) disk. So I use the hybrid with SAS and SSD, or I just use all SAS.
