One of the main feature why the storage systems became intelligent is by using the technique called RAID. A group of disk drives which combinely referred as an disk array are very expensive, have single point of failure and have limited IOPS. Most large data centers experience multiple disk...
Data is stored and accessed by applications using the underlying storage infrastructure. The key components of this infrastructure are the OS (or file system), connectivity, and storage. The server controller card accesses the storage devices using predefined protocols, such as IDE/ATA, SCSI, or Fibre Channel (FC) as discussed in...
Storage Arrays which are feature-rich RAID arrays that provide highly optimized I/O processing capabilities are generally referred as Intelligent Storage Arrays or Intelligent Storage Systems. These intelligent storage systems have the capability to meet the requirements of today’s I/O intensive next generation applications. These applications require high levels of performance, availability,...
The common model architecture of any vendor storage array may consist the below components.  Front-End Ports Processors (CPU) Cache Memory Backend Storage Disks Front-End Ports: These ports connect to the storage network and allow hosts to access and use exported storage resources. Front-end ports are usually FC or Ethernet (iSCSI,...
A storage array is a type of compute system designed to providing storage to externally attached servers through storage network. These storage arrays might be comprised of number of mechanical hard disks (HDD), Solid-state drives (SSD) or both together. In general, a storage array can have petabyte (PB) of storage space which...
Solid State Drives (SSDs) are storage devices that contain non-volatile flash memory. Solid state drives are superior to mechanical hard disk drives (HDD) in terms of performance, power use, and availability. These drives are especially well suited for low-latency applications that require consistent, low (less than 1 ms) read/write...
A hard disk drive is a persistent storage device that stores and retrieves data using rapidly rotating disks (platters) coated with magnetic material. The key components of a hard disk drive (HDD) are platter, spindle, read-write head, actuator arm assembly, and controller board.    I/O operations in an HDD are performed...
There are different types of storage devices which can be used for storing the data and based upon the business requirement & cost, storage devices are selected to be used in the storage system or storage array. There are three main types of media or storage devices which are currently...
In general, network connectivity is the process of connecting various components in a network to one another through the use of routers, switches and gateways. Similarly, storage network connectivity refers to the communication paths between IT infrastructure components for information exchange and resource sharing. The two primary types of connectivity...
Just as we can virtualize the physical servers and applications we can also virtualize the storage systems to access the data. Storage Virtualization can be defined as the pooling of physical storage from multiple network storage devices into what appears to be a single storage device that is managed...
