Cutting the ends off the roast…

When I used to teach, I always told the story of making the roast. It’s a parable, but it works. As follows: I was making a roast one day, and I cut the ends off it before i put it in the pan. My kid asks “Why did you cut the ends off the roast?” …

The “Public” Cloud…

It’s really easy to point-and-click yourself to a leased cloud or public cloud infrastructure.  Throw a credit-card # in and you can start working immediately. But it has to come down to the real question. Should you? Putting your application “In The Cloud” whether it be Google’s new service, Amazon, or anyone who you rent …

Multivendor or Single Source? Is there a right answer?

Every time I turn around it seems I seem to be running into the same question. Is it better to be multi-vendor or single source? Well the easy answer to that is, it depends.  Different vendors do things differently, work better/worse with some hardware, etc. The arguments in favor of a single-vendor solution is easy.  …

On tape…

Ok, I have no problem with tape.  It’s a *GREAT* backup medium when your requirement is portability for massive amounts of data and you’re not replicating said data. If I had to ship 400TB of backups to Iron-Mountain, to protect against the earthquake-to-end-all-earthquakes tape would be my FIRST choice (though maybe, as a GIANT CAVE …

No SAN is an island…

Ok, that was too cutsey for such a classy establishment. When you’re building a SAN, everything should play together, in the same SAN box if you will (with my apologies to QLogic.) When you start putting in multiple stand-alone SAN islands you increase your maintenance overhead exponentially.  You also prevent the very thing that make …

Backup Vs. Archive

The fundamental difference between BACKUP and ARCHIVE. A backup is there to help you deal with a crisis such as “My datacenter is a smoking hole in the ground now what do I do?” or something not quite as dramatic like “A virus ate my data.”  You recover from the backup to the last known …

VMWare Booting…

Ok, I’m curious as to whether anyone has an answer for this. Why don’t more people boot VMWare ESX from the SAN? It occurred to me the other night that I have 2 36G drives in each of my servers that I use possibly 10G of, when I already have a High-Availability storage solution at …

New look

I’m bored – bygones. Monday was another one of those days.  When will facilities people get it through their heads that …maybe it isn’t a GREAT idea to test the generator during the day… …maybe it’s something better done at night, on a weekend, or when the moon isn’t full… …maybe it’s a good idea …
