Block storage presents server storage as raw fixed-size blocks on a volume that the operating system formats and manages, as with disks, SANs and cloud volumes.
IOPS (input/output operations per second) measures how many read and write operations server storage completes each second at a given block size.
iSCSI is a storage protocol that carries SCSI block commands over TCP/IP, letting servers use remote disks on a standard network as if they were local.
A NAS, or network-attached storage, is a dedicated storage server that shares files over a network using protocols such as SMB and NFS.
RAID combines several disks into one logical volume using striping, mirroring or parity to improve server storage speed, capacity or fault tolerance.
A SAN, or storage area network, is a dedicated network that gives servers block-level access to shared storage arrays as if they were local disks.
ZFS is a combined file system and volume manager that pools disks, checksums all data and offers snapshots, compression and built-in RAID-Z protection.
