Last week, I let the cat out of the bag regarding the next Tech Field Day event, which kicks off in just three days! Today, let’s take a look at the great lineup of companies that will be presenting at this event. Many are new startups, including Nutanix, Pure Storage, and SolidFire, while others are more established, like Nasuni, Symantec, DataDirect Networks, Arista and Arkeia.
The Bridge: Veritas Thin (Provisioning) API
January 6, 2011 By 1 Comment
Thin provisioning needs communication to function, and zero page reclaim is only the array side of the story. WRITE_SAME helps reduce I/O load, but the server needs to use it. Wouldn’t it be nice if the operating system, file system, or volume manager would use these commands to help recover capacity?
Multipath: Active/Passive, Dual Active, and Active/Active
March 30, 2010 By 6 Comments
Although it’s rare in the PC world, multipath I/O is not new in enterprise IT. I’ve been juggling paths to storage and networks as long as I’ve been a systems administrator, and that’s a bit longer than I care to admit. But the proliferation of technologies has made it difficult to understand path management. What’s the difference between “dual active” and “active/active”? Is “active/passive” really that bad?
PowerPath To The Virtual People
April 22, 2009 By 5 Comments
Hiding in the shadow of the huge VMware vSphere 4 announcement was a very interesting introduction by EMC: PowerPath/VE. As I mentioned in my post on storage changes in vSphere 4, PowerPath/VE plugs into the new pluggable storage architecture (PSA) found in vSphere 4 versions of ESX and takes over the decision-making and heavy-lifting tasks related to communicating with storage systems.D
Symantec’s Thin API Is A Step In The Right Direction
October 16, 2008 By 21 Comments
Symantec announced that their widely-used Veritas Storage Foundation software (more commonly known as Veritas Volume Manager and filesystem) will now include thin provisioning, migration, and a new API which allows it to directly communicate with thin-capable storage arrays. This is a smart step, certainly, and ought to be useful, but storage managers should still try [...]
Volume Management: Virtualizing Host Storage
February 21, 2008 By Leave a Comment
I’ve been feverishly preparing for my upcoming TechTarget seminar series focused on storage virtualization, so I thought it might be interesting to post a few topics from the talk here on the blog. If you’ll be in Washington DC on March 4, or Durham NC on March 6 and are interested in the world of [...]
Storage Management Integrated with Server Virtualization (Where’s EMC?)
July 26, 2007 By 1 Comment
XenSource just announced that they’ll embed Symantec-née-Veritas‘ server-side storage virtualization software into their server virtualization offering. This is great news, since server virtualization has boiling for more than a year now with precious little storage integration to be seen. Although XenSource is a distant second in the world of server virtualization, they’re close enough to [...]
