Hard Disk Drives (HDD) for virtual environments (Part II) how drives differ

StorageNetworkingBy Greg Schulz, Server and StorageIO @storageio

In part I of this series we looked at basic Hard Disk Drive (HDD) characteristics and wrapped up with the question of what is the best type of HDD to use?

I often get asked why there needs to be different types or tiers of data storage devices including HDD and Solid State Devices (SSDs), along with interfaces, why not just one or a few? Continue reading Hard Disk Drives (HDD) for virtual environments (Part II) how drives differ

Public Cloud Reality: Reinforced at CSA Summit

CloudComputingI have written about the Public Cloud Reality and the need to bring your own security, monitoring, support. This was reinforced by Dave Asprey of Trend Micro at the last Cloud Security Alliance Summit held at this years RSA Conference. The gist of Dave Asprey’s talk was that YOU are responsible for the security of your data, not the cloud service provider. Unfortunately, this sort of discussion often devolves into one of shared vs tenant responsibility, the type of data, etc. It will also devolve into a legal discussion just as quickly. Unfortunately, all this does is point fingers. The long and the short of this discussion is about two items often mixed as one. Continue reading Public Cloud Reality: Reinforced at CSA Summit

RSA Conference: What was Interesting

RSA Conference: What was InterestingRSA Conference: What was InterestingAs I met with people at RSA Conference last week, the common question was: What was interesting and new? My view was from the world of virtualization and cloud security, which often differs from general or mobile security. This show was more about general and mobile security than it was about virtualization and cloud security due to the confluence of VMware Partner Exchange (PEX) and RSA Conference. There were quite a few things that were new from the show floor, RSA Innovation Sandbox, and other conversations. Continue reading RSA Conference: What was Interesting

Does Your Hardware Keep Up With Technology?

DataCenterVirtualizationDoes your hardware keep up with technology? Technology advancements have been and are moving at an incredible pace with new and exciting features getting added with each new release or update of a product.  Unfortunately, technology can outpace are physical hardware which can leave us in a true troubleshooting nightmare.  There is one specific example that I have seen a few times and is worth sharing.    Continue reading Does Your Hardware Keep Up With Technology?

News: Sky High Networks provides Cloud Service Security Ratings

CloudComputingThere has been a dearth of intelligence reporting on cloud services and up until now we had to rely upon the Verizon Breach Report, Alert Logic’s State of the Cloud report, the Enisa and other reports, but even so there was nothing specifically about a given cloud service outside the lightly used Cloud Security Alliances STAR self-certification. Instead you must imply something about a given service. This has changed. Meeting this need is Sky High Networks. Continue reading News: Sky High Networks provides Cloud Service Security Ratings

Atlantis ILIO Persistent VDI 4.0 – VDI Game Changer?

DesktopVirtualizationAtlantis Computing have released the first in-memory storage solution for persistent VDI. Setting aside the remoted experience, peripheral support, licensing and off-line access – the most nemesising nemesis for VDI is hardware scale. A major hardware limiting factor is storage performance.

In a transition from physical PCs to virtual work spaces you can move 50,1000,20,000 people from an environment where everyone has their own hard drive in their own device, to a shared environment where there are (hopefully) no longer 50,1000,20,000 hard-drives.  You do this to achieve cost savings. Still, in the majority of instances, the desktop file system and the apps that run on it weren’t designed to understand such consolidation. Many a desktop project fails because the storage infrastructure wasn’t architected with these mismatches in mind.

Yet, desktop virtualization solutions have have matured to accommodate such issues. A range of increasingly impressive VDI appliances: dedicated drive arrays. Way back in 2010 we were reporting that Atlantis Computing were looking to Transform Desktop Computing with their  In Line Image and Optimization (ILIO) product. Atlantis Computing’s core ILIO product sought to address optimizing non-persistent VDI instances, then offered a RAM based solution with their ILIO DiskLess VDI, then presented a way to optimize Citrix XenApp instances. Atlantis’ offerings look to dramatically reduce the physical hardware required to support virtualized desktop infrastructures.

And now to their portfolio, Atlantis Computing add ILIO Persistent VDI 4.0. Some early stability issues aside, Atlantis have developed a strong and supportive market and expanded on it. What is in this release? If 2013 is to be the year of VDI – how does  ILIO Persistent VDI 4.0 help? Importantly, will Atlantis Computing’s  ILIO Persistent VDI  change the game?
