Memory virtualization is allocating additional memory from the hard drive that are being unused to a virtual machine. Server consolidation is one of the main reason for the virtualization becoming more popular. The main idea of the memory virtualization is to convert the underutilization of the hardware that are already present. This results in significant cost saving, storage space and power consumption, this also results in rapid increase in availability.
Raid allows us to have a group of physical disks to form as one logical disk on the system. Using raid method of splitting the hard disk helps to read or write data at an increased speed, fault tolerance and redundancy. Raid 0 uses a form of striping. They have 2 disk which helps the data …show more content…
Storage repository is important when talking about snapshots because it impacts on the disk usage and performance. The first method is safer during the disk corruption because the snapshot backup will be safe and can be used to restore the data but when the file virtual machine gets damaged or corrupted, the backup gets lost with it and the data cannot be recovered.
Intelligent Storage System (ISS) is a new breed of storage system which provides feature-rich RAID array which provides highly optimized I/O processing capabilities. These storage systems are configured with large amount of memory called cache and multiple I/O parts and use sophisticated algorithm to meet the requirements of performance sensitive applications. Business critical application required high level of performance, availability, security and scalability, and therefore this will be most suitable for business applications to work with.

It contains of two key components; backend port and backend controller. Backend controls the data transfer between cache and the physical disk. From cache, data is sent to the backend and then routed to destination disk. Backend controller communicates with the disk when performing read and writes.
It is a semiconductor memory where the data is placed temporally to reduce the time required to service the I/O request from the host. Cache improves storage system performance by isolating host from the mechanical delays associated with rotating disks or hard disk drive. It increases the I/O processing because there is no moving parts in it. When the host issues the read request the storage controllers read tag ram to determine whether the required data is available in the cache, when the data is available in the cache it is called read operation with cache.
When upgrading the storage server, in NAS we have to copy all the files the old server to the new one, but in SAN it is easier because it is in clustered form which makes adding new storage servers seamless and any amount of storage can be added without having any downtime. When accessing files from NAS, we should map a drive(e.g. \\NAS-Server\ShareName) but if wanted to access storage on SAN it will be showing as an actual drive on the system (e.g. C:\,
