We were never able to achieve storage virtualization in mainstream enterprise IT because we lacked the ability to identify and move data non-disruptively. This has been solved by caching and distributed storage solutions, and it’s only a matter of time before the legacy need for centralized storage falls away.
As I have done since version 3.5, I’m charting the storage changes in VMware’s latest release of vSphere, 5.1. Unlike version 5, which included many new technical storage features, 5.1 mainly tweaks existing features and adds these new elements to the mix.
Once again, VMware added a ton of new storage enhancements to vSphere. With storage rapidly becoming the limiting factor in scalability and performance of virtual machine environments, this is no surprise. Also not surprising is the fact that major features like Policy-Driven Storage and Storage DRS (along with SIOC) are exclusive to “Enterprise Plus” licenses.
Lots of my IT infrastructure management clients are talking about how the advent of Ethernet/IP and virtualization is changing the roles of storage, server, and network administrators. The evolution of the storage role in particular in enterprise IT organizations has been a topic of particular interest to me for a while: I definitely remember thinking about […]
Many storage challenges focus on the conflict between data management, which demands an ever-smaller unit of management, and storage management, which benefits most from consolidation. Developing data management capability that is both granular enough for applications and scalable enough for storage is one key to the future of storage.
My travels last week kept me from posting my weekly round-up of interesting web content. So this week’s is a little heavy (and heavily edited!) Most important: Please register to be a marrow donor, especially if you might be a match for Nick Glasgow of EMC!
VMware officially launched their next-generation (version 4) enterprise family of products today under the “vSphere 4” name. As I’ve been doing for the last few major ESX releases, I’m focusing this post on the storage changes present in vSphere 4.
Like clockwork, VMware has cranked out another update to their flagship enterprise product, ESX 3.5. The last update came out in early November, 2008, and included some major new functionality. What’s in store this time to intrigue storage folks? Not much. For more information on earlier updates, see my articles: Storage Fixes in VMware ESX […]
Just over three months after releasing Update 2 for ESX 3.5, VMware has released Update 3. That last Update brought major storage changes like VSS support, hot VMFS extension, Storage VMotion across Fibre Channel and iSCSI, and support for 10 Gb Ethernet and 8 Gb FC support. For more information on Update 2, see my […]
VMware packed a lot into their 2008 VMworld conference, including an outline of their “three pillars” strategy, focused on vClient, vCloud, and something they are calling the Virtual Datacenter Operating System. While it is debatable if this last item really is an operating system, it’s certainly a major strategic change in messaging. VDC-OS is divided […]
