Storage virtualization

Storage virtualization: Storage virtualization is the amalgamation of multiple network storage devices into what appears to be a single storage unit. Storage virtualization is often used in SAN (storage area network), a high-speed subnetwork of shared storage devices, and makes tasks such as archiving, back-up, and recovery easier and faster. Storage virtualization is usually implemented via software applications. (Source: Webopedia)

Is VMware still the best choice for virtualisation solutions?


Section: Articles
The move to virtualisation is all but inevitable, and there is very little question as to why. The benefits are incontrovertible, and the maturity of the virtualisation software available has moved virtualisation out of the realm of the test bed and into the realm of "have to have it.” It may be true that some companies are reluctant to switch over to a virtualised environment if they already have an existing system in place and substantial capital sunk into a data centre, it is much more ...   read more

Virtualisation turns to open source for cost advantage and extensibility


Section: Articles
Virtualisation has become a de facto standard in larger data centres, particularly as they seek benefits such as greater processing agility and resource management. The cost factor, of course, weighs heavily in the decision—but whilst the long-term costs are favourable, in the short-term, it can be difficult due to a potentially high cost of adoption and the presence of existing --- and potentially not fully amortised --- data centre hardware. Overcoming ...   read more

Gmail Outage Due to Duel Network Failure


Section: News
Yesterday’s Gmail outage that’s reported to have delayed 29.1% of all email sent between the hours of 9am and 7pm ET was due to a duel network error, which caused two separate failures. Whilst it’s not known how many users were affected, as Google doesn’t provide daily email volume data, it’s a good bet that it was a fair few, as the service does have more than 425m active users. According to the search giants, the failure was picked up quickly by its engineers but it took them ...   read more

VMware Fixes Upgrade Bug


Section: News
Over the weekend leading virtualisation firm VMware warned its vSphere Replication 5.1 users not to install the newly released v5.5 and to check that automatic upgrades are disabled.
