It seems every year someone publishes a list of the top issues in IT, and every year backup issues are right up there at the top of the list. After 20 years of working on backup products, I find it a little disconcerting that backup remains a major problem.
Yes, I know what you’re thinking. “Solid-state disks aren’t new; they’ve been around for a while.” But so have Fibre Channel and SANs, and just like those technologies solid-state disks have been changing. And while in the past they were only used by a few high-end systems that required their unique properties, maybe now they’re something that everyone can use.
It’s been a while since my last post, and with summer officially over (I know most people think summer ends on Labor Day in the US, but the weathermen insist the official end is late September), it seems like a good time to look at a recent announcement. Among the flurry of press releases at the recent VMworld 2008 in Las Vegas, there was one in particular I’d like to discuss.
Tape backup is still the most prevalent technology in place for dealing with data protection, and array based replication is still the most common method of protection for mission critical applications, but companies are really starting to like the idea of saving money by innovating in how they attack the largest ongoing IT costs, which is still backup and disaster recovery.
The term virtualization has been over used and over hyped by many companies, and this misuse of the term virtualization has caused some confusion. Simply put, virtualization means “abstraction”. The virtualization solution abstracts the underlying details and complexity of whatever it is virtualizing.
In light of the events at the recent VMworld conference, this post should be timely. In my travels lately I have been bumping into a lot of organizations suffering the pain and turmoil of moving from a physical environment at their production datacenter, to a virtual environment for DR.
Thin provisioning may actually get you 30% or more better utilizaiton from your storage, but what else can you do to have an even greater impact?
Data deduplication is one of the most obvious choices for reducing overall infrastructure costs within the data center, which also reduces power, cooling, and floorspace requirements for IT. Data deduplication at the file level (unstructured data) can be used to reduce duplicates within production storage.
In part 1, I discussed how to leverage Virtual Tape to green the datacenter and the environment. In this part, I will focus on how storage virtualization can help reduce power consumption and datacenter floor space requirements.
One of the hottest topics in IT these days is "Green". When the term green is used in reference to IT, it usually means more than just being environmentally friendly. For Information Technology, green also means needing less money to pay the bills for power, cooling, datacenter floor space, and the gas needed to ship tapes back and forth between the datacenter and offsite storage or DR location.
