HP Storage

HP is one of the best and largest manufacturers of NAS storage devices and related licenses. Large companies and organizations use the after-sales service and various licenses of its products by ordering and purchasing HP’s products.

HP NAS or Network Attached Storage

NAS or Network Attached Storage, are hard disks located on the server. These storage devices can be shared and used by all network users after locating in the network system. After placing these storage devices on the network, each user connects to the storage via the TCP / IP protocol and receives service from it.

These storages provide a central and accessible space to store critical files and folders for any organization at an affordable price. In this method, the data access model is “File Level Access”, which means that we have to install optimized windows for storage on NAS storage.

HP SAN or Storage Area Network

There is another type of storage that is more expensive than NAS memory, called SAN or Storage Area Network. The main difference between NAS and SAN is the block level of SAN storage. The File Level Access feature allows data to be read at a slower rate and increases LAN traffic.

These devices have an operating system and use the storage server version of operating system. For example, the Microsoft version of this type of operating system is called Windows 2012 Storage Server. In this Windows, services such as DHCP and Active Directory cannot be activated, and instead File Sharing has been optimized. NAS is commonly used for File Sharing and Home Directory.

SAN storage provides block-level network access for storage (the structure of data storage in this type of network is Block Level. SAN storage devices typically consist of hosts, switches, storage elements, and storage devices that are interconnected using a variety of technologies, topologies, and protocols.

A SAN storage is actually a network of storage devices that connect to servers. This storage device stores the data at the block level to be used by the software installed on the servers of this network. This equipment eliminates the dependence of data storage devices on servers and can play a separate role in the network. It is natural that any software on any server in the network can access these storage resources, and this will increase the efficiency of SAN equipment in the network.

This device has Block Level access, which means that it can directly access the hard disk blocks, which increases the speed of the system as much as possible.

Fiber Channel communications are the most widely used SAN equipment today. But SAN solutions are not limited to fiber optics, and there are other standards, such as iSCSI that provide iSCSI communications. You can even use FCOE or Fiber Channel over Ethernet. To activate various port functions on the HP storage servers, specific HP License types would be required.

The Main Difference Between SAN and NAS

Devices that access the SAN using the Block Level structure manage their own files. In NAS storage, however, file management and access controls are the responsibility of the device’s operating system. Unlike NAS, on SAN storage devices, access protocols are not file-based and are based on Block Level Access. Examples of these access protocols used in SAN are iSCSI and Fiber Channel, which provide access to information on the network in the form of Block Level.

SAN Storage Advantages

  1. Save money
  2. High availability
  3. Business continuity
  4. Centralized management
  5. Backup and Restore faster
  6. Better information security
  7. Server and storage integration
  8. Better data protection and fast recovery
  9. Increase program performance by loading storage or network isolation functions

Factors Affecting Network Performance

  1. Data rate
  2. Bandwidth
  3. Throughput
  4. Service time
  5. Request size
  6. Request rate
  7. Response time
  8. Reading and writing rates

HP DAS or Direct Attached Storage

DAS or Direct Attached Storage is a digital storage that connects directly to the Storage Controller of a computer or server. We use this technology when the volume of information is very large. So by adding DAS, you can increase the number of different hard drives under your server management.

In this type of HP storage, the server itself does the work of formatting, reading and writing data, and in fact its access level is Block Level. One of its first advantages is its simplicity and low cost. DAS is installed on most PCs and some servers, and if you want to add more DAS, just buy a device and a cable. This technology is the cheapest type of storage and suitable for small, medium companies and branches of large companies.
