HP Enterprise Storage

The HPE Storage (formerly HP StorageWorks) is a portfolio of HPE storage products, includes online storage, nearline storage, storage networking, archiving, de-duplication, and storage software.

HPE 3PAR StoreServ Storage is a family of flash-optimized systems that offer rapid, and automated provisioning. It leverages a multi-tenant design, and uses hardware for deduplication. Furthermore, it does all this in a single, tier-1 storage system designed for data security, and availability.

The EVA family supports Serial Attached SCSI (SAS) disk drives with a wide range of Small Form Factor (SFF) SAS drives, Large Form Factor (LFF) SAS drives, or combinations of both, to better match customer storage capacity, performance, power, and availability needs




Differences between SAN and NAS storages.

Both SAN and NAS (network-attached storage) are methods of managing storage centrally and sharing out to multiple servers, but a few differences distinguish them from each other. Primarily, NAS is more abstracted than SAN storage. NAS partitions storage into files, folders, and volumes that are managed by a head unit, which means the data is entirely independent of the connected devices rather than being stored in blocks made up of logical unit numbers (LUNs) as in SAN.

Both also use different methods of sharing stored data: SAN shares to a dedicated network, while NAS uses a shared network. Additionally, SAN and NAS differ in their transport capabilities. NAS uses Ethernet, while SAN can use both Ethernet and Fibre Channel.

The benefits to each vary as well. SAN focuses on high performance and low latency, while NAS targets ease of use, manageability, scalability, and lower cost.

The protocols used by SAN and NAS.

Storage area networks use four protocols: FCP (Fibre Channel Protocol), iSCSI (Internet Small Computer System Interface), FCoE (Fibre Channel over Ethernet), and FC-NVMe (Non-Volatile Memory Express over Fibre Channel). When serving data using any SAN protocol, a user may need specialized hardware to transport storage area network traffic.

For example, different switches and network cards might need to be deployed, or even converged network adapters (CNAs) that allow hosts to offload some CPU processing. These dedicated resources help to improve performance.

By contrast, NAS uses protocols shared by other types of servers (Windows and/or LINUX)—Common Internet File Services / Server Message Block (CIFS/SMB) and Network File System (NFS). These protocols make data storage easier to manage. They also allow the network to use infrastructure that already exists on the end user’s system.
