So tonight as I was getting into bed I did my normal scan twitter to see who I have pissed off or what might be going on that should rob me of sleep.  Well tonight @david_Strebel asked the following questions;

“Who thinks FCoE will win over iSCSI?”  and I responded “Not I” and then David asked the next logical question which was why not and here is what I had to say in the incredible detail that Twitter allows;  ”l2 boundaries, specialized hardware other than nics, hate relationship from most network people.”

The problem with this answer is pretty clear though.  It does not really answer the question just gives a few power point bullets to appease the crowd.  I don’t feel like this is enough though.  So I am going to attempt to lay out my overall view on this issue of who will win iSCSI or FCoE and why.  For those of you who don’t want to read the whole article which might get a a tad windy I don’t think either will win.  But I don’t think FCoE will emerge as the leader until something better come along.  For those masochists who like this kind of crap read on.

Find yourself trying to decipher your Cisco CDR exports? Your not alone. I’ve got to give credit to some folks who helped me out – especially since I’m using Excel for MAC 2011.

Found this on Blindhog.net – smart guys!

Are you using Excel for MAC 2011 and find your year is off by 3?
You actually need to change the hack digits at the end of your formula from 25569 to 24107.
Check out this link.

Also, I was struggling with getting my human date and time to match that on www.epochconverter.com using the formulas above. It was off by 3 or 4 minutes. I found that if I removed the outermost set of parenthesis, then my formula actually matched the exact minute, as verified in the picture below.

Hope this helps some of you out rather quickly. Enjoy.
BTW, using the eastern time formula above, I was still off a little, so I simply added another hour (4*3600).

Quick and dirty is how I like it when I have 4000 menial tasks to get done.  So another oldy but goody that I had to dig up today was how to delete a full directory structure and its contents from a Cisco files system.  So here it is enjoy.

From normal enable mode:

delete /recursive /force flash:(enter the root file name)

So delete is the easy one.

/recursive sets the flag to recursively cycle through the whole directory structure you specified.  So you should probably never type

delete /recursive /force flash:  BAD DON’T DO IT!

And finally /force eliminates all the are you sure you don’t want to shoot yourself in the forehead messages.

Again quick and dirty saves time but if your dumb about using it can get you in trouble.

So last night while working on a Scalable Compute and storage design for a client, this post popped up in my twitter stream from @ErinatHP;

“New HP blog post “In the light of day – the Cisco UCS hype doesn’t match the promise” ; UCS not all its marketed to be http://bit.ly/dKj88W”

So in my normal do not let a stupid dig by a lame duck player go unmatched I responded “Oh I can’t wait to read this FUD” (you can check me out on twitter @joshobrien77)

All the twitter marketing and pissing matches aside I meant what I said and I did look forward to reading the HP Spin on where their market is vanishing to.  And here are my responses, while they might not be the most technical they are not un-informed from the basis of the Cisco UCS platform or the HP C7000 with FLEX-10 Platform.  And remember at the end of the day I represent me not Cisco not my employer, just little old me.

Also just so if this gets nasty I want to make sure that I am crediting this correctly:

All of the HP Writes: Are direct Quotes from Duncan Campbel with HP on his blog which you can find here:  http://h30507.www3.hp.com/t5/Converged-Infrastructure/In-the-light-of-day-the-Cisco-UCS-hype-doesn-t-match-the-promise/ba-p/83537

I have been through a couple of these Nexus deployments now that use a combination of 7Ks, 5Ks, and 2Ks. If you know anything about this platform you know that TACACS and AAA only really apply to the 7K and 5Ks. Here is my working template of what it takes to get these guys talking to and ACS server.
