Register > Solid State Disk (SSD) technology is one of the hottest IT areas in 2012. The promise to eliminate storage IO bottlenecks and increase application performance, enable server virtualization, enable data center growth, and reduce IT costs has prompted 83% of all IT departments to consider SSD. But those planning an SSD deployment face a variety of deployment choices. Moreover, choosing poorly can yield large expense, disruption to existing IT environments, and a complex new set of storage management tasks. Join Brian Garrett, Vice President at the Enterprise Strategy Group, Inc. and Peter Velikin from VeloBit, Inc. for a comprehensive overview of the key considerations you must make when building your SSD strategy. This webinar is intended to help IT executives make wise decisions. You will see first-hand research on the actual vs. perceived benefits organi... (more)

Introduction to Virtual Desktop Infrastructure (VDI)

This blog starts a series of blogs we will post regarding Virtual Desktop Infrastructure or VDI.  To directly quote wikipedia "VDI is a desktop-centric service that hosts user's desktop environments on remote servers and/or blade PCs, which are accessed over a network using a remote display protocol."  Basically, VDI means a user can access their desktop from any terminal device capable of running the remote display protocol.  Further, VDI runs a complete implementation of a typical desktop OS (e.g., Windows XP, Windows 7, etc.) as a virtual machine on the host server.  There i...

SSDs: The Beginning of the End for RAM Caching?

For years, the solution to IO bottlenecks has been pretty consistent: (1) add spindles to decrease seek time and increase throughput, and (2) add as much RAM as you can so your filesystems and applications can cache hot data and avoid disk access entirely.  These brute-force attempts to gain performance are inherently flawed and costly.  The price of increasing the number of disks in an array adds up quick, to say nothing of the investment in additional JBODs when you run out of slots in your array.  And although the cost of consumer-grade memory has fallen, relying upon RAM for...

Maximize the Advantage of SSD Caching

File System Alignment for SSDs There are many techniques and methods that can be used to tune an IT system to improve overall system performance.  SSD caching is widely being used as a low cost, easy to implement method to quickly increase performance with little or no impact on existing operations.  One thing that needs to be considered when choosing SSD caching is how to configure a file system to maximize the performance increase SSD caching provides. Operating Systems and Block Size In the past few years, the sector size of HDDs has increased from 512 bytes to 4k bytes.  Relat... (more)

Doggin’ It with VDI

Hey there; the IT Dog back with some color commentary on our VDI experience. When I first heard the name, I thought VDI was the latest model Volkswagen diesel, but as the guy with the suit explained in the last blog, VDI is Virtual Desktop Infrastructure.  Now that you know what VDI means, I am sure you know all there is to know about it, right?  Well, I wish it was that easy for me. Where Do I Begin? I guess I’ll start from the beginning.  At my company, my IT guys were at their wits end trying to manage the 1000 or so desktops, spread out over four different locations, with va... (more)
