Storage virtualization software makes the use of standard hardware as a central axis for sharing the storage for the virtual machines and the Virtual Desktop Infrastructure. in an previously published article, the basics of storage virtualization has been discussed.
As it has been discussed by the other authors in this website, Virtualization for servers requires massive and powerful storage system – preferably a central storage. Storage Virtualization Software for storage virtualization layer used as a way for central administration for different storage devices.
Storage Virtualization Software and core functions of Storage Virtualization
A redundant hardware setup is essential for virtual servers and desktops and storage infrastructure for high availability and requires a dual hardware arrangement.
Storage virtualization software, however, provides a hardware independence and facilitates memory expansion and they should not replace the redundancy requirement.
Storage virtualization Software-only solutions that address the environments of all types are usually installed to two or more physical 32 bit machines. These Storage virtualization software turns them into a dedicated storage node via virtualization – may be integrated through fabrics.
Storage virtualization software and High Availability
Since the IO demands are high, especially in the virtual infrastructure, at least three dual port HBAs should be installed for connecting to the storage network. The connection in between can be through Fibre Optic Cable, Ethernet. Hardware switch along with good stable network, reliable Storage virtualization softwares make the total system highly available.
To summarize within few words about the Storage Virtualization Software and high availability :
Disk-pooling and provisioning, Central management platforms, Emergency backup, specific embedded host, good network bandwidth along with the real skill of the management and engineering unit creates the High Availability Storage solutions. Storage Virtualization Software plays a pivotal role, however using only a software can never make a brand’s High Availability Infrastructure Project a reality.
