VMware Acquires Virsto To Enhance Virtual Storage Performance
February 12, 2013 05:11 PM
VMware is acquiring Virsto, which provides software to accelerate virtual machine I/O and improve overall storage performance in virtual environments.More on Performance Metrics: The Relationship Between IOPS and Latency
August 09, 2012 10:14 AM
The best predictors of storage-related application performance have always been latency and IOPS. Hybrid SSD and HD systems are changing how those numbers should be viewed.Is Intel's Romley for You? Getting the Most Out of the Xeon E5-2600
July 30, 2012 10:40 AM
Intel's Xeon E5-2600 supports PCIe 3.0. The increase in performance can substantial, but it can also be lost if I/O peripherals aren't up to the task. Here are the details on the new Romley chips and how to best take advantage of them.Thought Experiment--Forget ROI
January 23, 2012 09:50 AM
Boys and girls, today's homework assignment is a thought experiment. I want you all to put yourselves in the shoes of the CXO team making a decision to move to private cloud. There is, of course, one catch: You may not factor in ROI. We're dropping ROI because it clouds the subject (bad pun intended.) Let's skip the why-should-I-do-this-experiment; I'd of course default to,"Because I told you so."Dealing With VMware's I/O Challenges
September 01, 2010 10:36 AM
One of the key themes at VMworld this week is dealing with the I/O challenges that a physical host loaded up with a dozen or more virtual machines places on the storage and the storage infrastructure. This is caused by consolidating hundreds of I/O friendly stand alone systems into a few dozen hosts. While virtualization reduces the number of physical servers, it now makes every server an I/O nightmare.I/O Virtualization: When, Not If
August 05, 2010 03:15 PM
I/O Virtualization (IOV) is an I/O card-sharing technology that lets multiple servers share multiple cards across a single, high-speed cable segment. The general purpose of IOV is to make it easier to share bandwidth among servers in a rack. The cards to be shared are placed in a gateway, and the servers connect to that gateway. Cards are typically shareable on a per-port basis. For example, a quad-port Ethernet card could be assigned to four different servers. The ports or cards can be quickly assigned and re-assigned to the connecting servers, providing some hot-swap like functionality to PCIe. IOV is still in its infancy, but it is destined to become a standard component of a data center architecture.Deduplication And Solid State Disk, A Perfect Match?
June 30, 2010 08:00 AM
Solid State Disk (SSD) is the medium that storage managers are looking at to address storage performance problems in their environment. Deduplication is what they look at to address out of control capacity requirements. Rarely do you see the two technologies linked, but these two may be a perfect match.Desktop Virtualization May Break Storage
June 18, 2010 10:00 AM
As day two of the BD Event drew to a close, the closing keynote was delivered by Peter Levine of Citrix. Mr. Levine gave an excellent presentation on desktop virtualization and closed with a warning for storage vendors. The key issue is the impact that desktop virtualization will have on storage capacity and I/O demands, and desktop virtualization vendors need help addressing it.The Challenges of Legacy Storage
June 03, 2010 11:30 AM
Sometimes it's tough being a legacy storage supplier. To maintain backward compatibility, your early success sometimes becomes your greatest inhibitor. We've seen some of these legacy vendors struggle to bolt on capabilities like virtualization and thin provisioning to existing platforms. There is foundational change being driven by hardware advances like Solid State Disk (SSD), Serial Attached SCSI (SAS) and Massive Array of Idle Disks (MAID).The Acceleration of Bandwidth Adoption
May 07, 2010 10:52 AM
For many data centers the move from one level of bandwidth speed to another happens primarily when that upgrade in speed is the same price as the current speed. For example 8GB Fiber Channel (FC) is now almost the same cost as 4GB FC so it makes sense to finally begin that upgrade process. However my expectation is that the next wave of bandwidth upgrades will come at a substantially accelerated pace.1 | 2 | Next Page »
