What is VMware VASA? Not Much (Yet)

VASA allows a "provider" application to tag vSphere storage with a "capabilities" string

VMware is adding storage integration features to their flagship vSphere server virtualization product line at a rapid pace. From backup to enterprise array offload, VMware is staking their claim. But information about one new storage feature in vSphere 5 has been scarce: The true nature of the Storage API for Storage Awareness (VASA) is only just beginning to be revealed.

Storage is Not Getting Cheaper

Slide25

Why do we care about thin provisioning? Because storage is not getting cheaper. If you went to buy a disk ten years ago, you’re going to spend about the same as would today, but you’re going to get a lot more capacity – a lot more capacity! The fact that we have terrible utilization of enterprise resources is really not helping us, and it’s not getting any better. It hasn’t improved because they are “doing storage” the same way.

The Four Horsemen of Storage System Performance: Never Enough Cache

Write-Through Cache

Perhaps the previous discussion of spindles left you exhausted, imagining a spindly-legged centipede of a storage system, trying and failing to run on stilts. The Rule of Spindles would be the end of the story were it not for the second horseman: Cache. He stands in front of the spindles, quickly dispatching requests using solid state memory rather than spinning disks. Cache also acts as a buffer, allowing writes to queue up without forcing the requesters to wait in line.

Could Oracle’s Next Acquisition Be HP or NetApp?

Larry Ellison is on a tear at Oracle. Who will he buy next?

Oracle has its sights set very high. Although the company is best-known for its namesake database software, a steady string of acquisitions has transformed the company (and its colorful leader, Larry Ellison) into an industry powerhouse. Much speculation revolves around Oracle’s next move, and a surprising meme is developing, suggesting that the company is looking at making another massive purchase. Could HP or NetApp follow Sun into the hands of Oracle?

The Enterprise IT Acquisition Game

The players are lining up for the biggest acquisition game enterprise IT has witnessed in a while

Today is the (a?) day of reckoning in the 3Par saga, with Dell widely expected to make a counter-offer higher than HP’s bid. But this mega deal, like the Data Domain war before it, sends a strong signal to the enterprise IT world: It’s open season on data storage companies! But the rising superpowers are also likely looking at networking as an area of expansion. The game is afoot!

Microsoft’s Overlooked Innovation

Silicon Alley Insider's Dan Frommer and Kamelia Angelova presented this chart of Microsoft's profits on Feb 10, 2010

It’s fun to bash Microsoft. It’s easy, too, with Apple solidly conquering the high end of the PC and mobile markets and Google’s command of the Internet. But how fair are these articles skewering Microsoft, such as “Microsoft’s chronic lack of innovation” published today at Techworld? I suggest that Microsoft innovates as well as, if not better than, any other massive company. But no one innovates like an outsider.

WeFollow: The Passive Twitter Directory

Kevin Rose announced the availability of an interesting new service at the March, 2009 South by Southwest festival: WeFollow is a passive, user-generated twitter directory. The genius of WeFollow is that there’s not account to create and no complicated setup. You simply send a tweet to @wefollow with up to three hashtags and your account [...]
