Best Nerd Movies of all time.

Yeah – one of those posts.  But I’m not talking about the latest blockbuster, and I’m not even talking about anything even remotely “Matrix-Like” (though it does make the list) I’m talking about the movies us techie-types hate to admit that we loved. Here they are: Honorable Mention: Short Circuit – campy but loveable.  Good …

AS400 –

It’s 4am – Just finished an AS400 migration from 8830 to DMX – Went swimmingly well.  Shut down the system, swing the cables, split the RDF, and boot it back up.  Since it’s a direct-attach there is no pesky zoning or masking to deal with. 🙂 AS400’s are an odd beast.  The only way to …

VMWare disk problems…

Ok, I’ve been playing more and more with VMware lately.  All of it personal, because the work opportunities just haven’t really presented themselves. In relocating one of my “production” servers to the Fibre array I purchased recently, I ran into a problem.  I realized that I was doing it wrong and tried to cancel out …

Overcomplicating the world

Ok, I’ve seen it happen over and over again.  Customers who think they know better. Now I absolutely applaud a customer who wants to take the time to learn the ins and outs of the storage they’ve spent probably  hundreds of thousands of dollars on. But when you pay a consultant to come in and …

Migration complete –

We did it.   Migrated the hosts/data.   Production is now running in Kansas, DR in Georgia, and the old datacenters in NY/NJ are one step closer to being shut down. Interesting couple of things I learned today. SRDF/A is a great technology for replicating over long distances while maintaining what they call a “dependent-write-consistent” state.  It …

Binfile changes

The joys of data migrations.  One of the most common problems is the standard practice of most companies to avoid upgrading whenever possible.  The “if it ain’t broke, don’t fix it” mentality. I could spend days and days on that particular brand of suicide.  For now I’ll just replace that addage with a new one. …

The beatings will continue…

…Until morale improves. Trying to run 4, FCIP trunks over a half a DS3 is a lot like raising a teenager. Sometimes it looks like it’s working, but in reality it’s just screwing around playing video games. Actually, my favorite is that “Raising a teenager is like trying to nail JELL-O to a tree”  I’m …

Cheaper isn’t necessarily better.

This is a large part of what drives me nuts about customers.   (If they didn’t pay the bills, I’d be for letting them all drown in the sea of bad decisions they make)  The unwillingness to spend a little extra to do it right. Let me give you an example.  I’m working now on a …

Cisco FCIP and SRDF

Been a while since I’ve written anything – I’m not even sure if I still have a readership. I’ve been working an average of 60 hours a week on a single project these days.  Doing a datacenter migration and consolidation.  Basically moving 4 Symm-5 generation systems into a single DMX-3. The funniest part of this …

SRDF over what media?

Well – Tomorrow I should have data replication going between the two Symms.  And it gives me pause. We’re going to be using SRDF/A for our replication.  To those who are not familiar with the EMC terminology, SRDF/A is a “Semi-Asychronous” form of SRDF that provides consistency points in the data being transmitted without affecting …
