Spent Saturday morning re-provisioning resources in our virtual env. Quite recently we had 100 VMs running on 3 Hosts. CPU utilisation is under 20% always but RAM consumption was literally maxed out across all hosts. When I began looking into the VM utlisation we had VMs with 4GB ram and consuming 10% of that. Most of these VMs come from requests such as "must have 4GB RAM and 500GB HDD" then find out it's only using 10% and 9GB on the HDD but now your overallocations are all screwed up in the 1000's of % overallocated.
It's mainly one guy requesting this and he kicks up a fuss. Going to have to lump it now, as the rediculousness began impacting prod systems. From 4GB ram down to 768mb with guaranteed 512mb :) :XD: >:D Worst case scenario I can hot-swap more RAM during business hours.
I've been monitoring this since before Christmas, in a server audit doc so I done some basic profiling before making the changes.
Upgraded the OS on the SAN - love this NimbleStorage SAN. It's as easy to manage as making a cup of coffee. But I still have a problem where the controller failover triggers the VM env. to pause the VMs. I have a document to read, I have to make some minor config changes to the iscsid and multipathd settings next week.
And then I can deploy another OpenStack instance :)
Careful, though... some systems freak out if they don't have that 4GB of RAM that they were promised, especially virtual ports of hardware.
Just arrived in Budapest. One of our offices is moving so perfect chance to standardize (ie get under control) the network here. Here until Saturday, hope I don't get into major issues so I can see some of the city on Friday :pub:
Man, they cut our travel budget. Now I have to see Europe on my own nickel.
So I didn't see anything of Budapest itself last week, too much lost on the physical move. Actual network was fine though, I love building from scratch in an empty rack :) They did give me a book with pretty pictures as a souvenir, maybe I should go back for a weekend trip soon.
This weekend I'm in Portugal for another office move. Working tomorrow and Saturday, and they want me here on Monday to support so on Sunday I can cruise along the coast 8)
And after that, I'm staying put for a couple of weeks...
Office move in Nigeria today (remotely :whistle:), two sites are being merged into one. Remote firewall is a Check Point, I hate Check Points.

Fun fact: I've never logged into any of the CheckPoints at where I work. I leave that to others. In exchange, they don't have to touch NAC.
We all dread the day we implement a CheckPoint integration module with our NAC solution...
Just spent 5 days moving and replacing a network in Sweden, tired af. Sweden is a great place, but you can lose a fortune on alcohol :)

It's Check Point, they want you to use the GUI
:flipdesk:
Now that I'm at $VENDOR, I don't have to mess with CheckPoint. At all. :smug:

Went to Switzerland to set up a office there years ago. Loved it but buying a simple burger and a beer was extremely funny trying to guess how high the bill was going to be :)

Yeah, that was probably the only country where I couldn't eat a real main course because of budget constraints, it's crazy. But the Swiss do earn about twice as much as other Europeans.
Last project finished today in Germany, now I have five more days to finish documenting everything I did in the last three years and it's on to the next assignment, probably no more travel - mixed feelings!
