Restoring an Exchange 2007 mailbox using EqualLogic’s ASM/ME
Ask most IT Administrators in small to medium sized organizations to recover an Exchange mailbox, and you’ll get responses like, “how important is it to recover it?” and “How much of it is gone?” You might even get the slightly patronizing “Oh, well you were close to your storage quota anyway” This is…

Replication with an EqualLogic SAN; Part 4
If you had asked me 6+ weeks ago how far along my replication project would be on this date, I would have thought I’d be basking in the glory of success, and admiring my accomplishments. …I should have known better. Nothing like several IT emergencies unrelated to this project to turn one’s itinerary into…

Replication with an EqualLogic SAN; Part 3
In parts one and two of my journey in deploying replication between two EqualLogic PS arrays, I described some of the factors that came into play on how my topology would be designed, and the preparation that needed to occur to get to the point of testing the replication functions. Since my primary objective…

One feature that I haven’t been able to use is the built…

Using OneNote in IT
It’s hard to believe that as an IT administrator, one of my favorite applications I use is one of the least technical. Microsoft created an absolutely stellar application when they created OneNote. If you haven’t used it, you should. Most IT Administrators have high expectations of themselves. Somehow we expect to remember pretty much…

Comparing Nehalem and Harpertown running vSphere in a production environment
The good press that Intel’s Nehalem chip and underlying architecture has been receiving lately gave me pretty good reason to be excited for the arrival of two Dell M610 blades based on the Nehalem chipset. I really wanted to know how they were going to stack up against my Dell M600’s (running Harpertown chips). …

Resource allocation for Virtual Machines
Ever since I started transitioning our production systems to my ESX cluster, I’ve been fascinated how visible resource utilization has become. Or to put it another way, how blind I was before. I’ve also been interested to hear about the natural tendency of many Administrator’s to over allocate resources to their VM’s. Why does it…
