What is SAN storage? 

A SAN is a storage area network that provides dedicated block-level data storage. The SAN stores a pool of data at the block level, and the storage capacity can be allocated to different workloads.  SANs are typically more efficient with higher throughput since they can easily manage storage at block level.

What is NAS storage?

NAS is network-attached storage which provides file-level data storage.

What is the difference between a SAN and a NAS?

Typically data storage running block-level SAN requires a server to allocate the storage capacity.  SANs typically use Fiber Channel connectivity and are utilized often with structured data workloads (i.e. databases).  NAS storage typically uses Ethernet connectivity and frequently used with unstructured data (i.e. video & medical images).

What is Unified Storage?

Unified Storage means that multi-protocols can run on the same storage device.  This eliminates the need to find separate NAS and SAN devices. PAC Storage can run both SAN and NAS within the same storage array at the same time under different volumes of data pools. You also can run different protocols within the same unit giving much more flexibility.

What is NVMe? 

NVMe is nonvolatile memory express, a protocol for flash and next-generation SSDs (solid state drives). NVMe delivers the highest throughput and fastest response times for all types of enterprise workloads.

What is iSCSI?

iSCSI is Internet Small Computer Systems Interface.  iSCI is a data transfer protocol.
