Where In The World Is Twitter's DNS?
Twitter lost control of its DNS records on Dec. 17 for about an hour, but the effects lasted a bit longer due to DNS caching. While neither Twitter nor their registrar DynDNS, is saying much other than that the DNS records were changed at around 10pm PST, there has been ample speculation that the perpetrators got control of administrative credentials for Twitter.com.

Citrix Receiver On Android: Your Desktop Anywhere
December 17, 2009 9:00 AM
Posted by Mike Fratto, Editor
Citrix's Receiver for Android is available as a Tech Preview (beta, don't use in production, etc) and runs on Android 2.0. Receiver, which Citrix expects to be out of Tech Preview and generally available by Q2 2010. Receiver is the company's universal client for desktop and mobile devices, providing a seamless remote application experience to end users regardless of where they are and what device they are using. Receiver on Android is surprisingly usable, given the Droid's relatively small screen compared to a netbook or small laptop. Receiver is also available for the iPhone and Windows Mobile devices. Blackberry support is planned.

Gridstore Puts Scale-out NAS In Reach Of SMBs
December 17, 2009 8:32 AM
Posted by Howard Marks
I've always been partial to scale-out storage systems based on the RAIN (Redundant Array of Independent Nodes) model. If data grows faster than predicted, and it always does, I can just add another node or two to the cluster (or grid, cloud, fogbank or whatever the vendor wants to call it), and I never have to fire up the forklift for an upgrade. Now, an Irish startup, Gridstore, is taking the idea downscale by bringing the per-node cost of their SMB NASg to just $400.

Will They Make It? The Perfect Presentation
December 17, 2009 8:30 AM
Posted by George Crump
I heard this question twice yesterday, once from a CIO and once from a financial analyst: "Why won't they just tell me what their product does?" It's not the first time I have heard that plea, and I'm sure it won't be the last. One of the ways to tell if a company will make it is how quickly can they get you to understand why they exist and what makes them different.

Deduplicating Replication - Data Domain
December 16, 2009 12:41 PM
Posted by George Crump
Data Domain is the next up in our re-interview blogs. As I have said, the deduplication method used will have impact on how replication will work in the environment. Data Domain is an inline only system. That means as data comes in, it is deduplicated on the fly. As a result, the replication process should be able to start sooner. Data Domain has been delivering replication capabilities for a while, and their product has some advanced capabilities.

Automated Storage Tiering: EMC Is Moving FAST!
December 15, 2009 10:55 AM
Posted by David Hill
EMC has just launched the maiden version of its FAST (Fully Automated Storage Tiering) software that will run on all of its main storage platforms, Symmetrix, CLARiiON and Celerra. FAST addresses a key question for modern storage systems: in what tier should the data be placed within an array? That issue has been complicated with the recent addition of solid state disks (SSD) in the form of flash memory drives (say Tier 0) in addition to Fibre Channel (FC) drives (Tier 1) and high-capacity SATA drives (Tier 2). Note that practically speaking, the SATA drives are not an active archive as the placement of the data is at the block level and not at the file level, such as with Centera CAS (content-addressable storage). However, the Celerra FAST can move to locations inside or outside of an array—such as another Celerra, Centera or ATMOS—for archive purposes.

Harnessing vSphere Performance Benefits For NUMA: Part 2
December 14, 2009 5:32 PM
Posted by Jake McTigue
In my last post I talked a great deal about native support for NUMA in vSphere on enabled Opteron and Nehalem processor platforms. NUMA is a strong technology in and of itself, but it really starts to shine when teamed with other supporting technologies. In this post, I'm going to cover the details of integrating next generation networking and interrupt technologies to improve storage and networking performance. I'll focus on MSI-X, but future posts will cover VMDq, RSS and Multiple Queue's in more detail, as all these technologies work closely to distribute load to multi-core CPUs and dramatically improve system performance.

One of the great ironies of storage technology is the inverse relationship between efficiency and security: Adding performance or reducing storage requirements almost always results in reducing the confidentiality, integrity, or availability of a system.
