After about a year of being a member of the community I am now Stack Overflow Valued Associate #9 (Or Server Fault Valued Associate #1 if you like).

Besides trying to keep these sites up I will also be writing posts for the [Server Fault Blog][2].

@Isaac: Also netstat, if they won't let you have netstat you might want to start searching the job market before you go nuts ;-)

comment How does vm.overcommit_memory work?
@MikhailMorfikov: Yes, practically I think 0 makes the most sense. In my environment, the only time I enable 1 is for Redis, which does stuff where it expects do be asking for a lot more memory that it is using due to a fork(). The child will pretty much use all the same memory pages, but Linux doesn't know that says to be safe it has to assume 2x memory will be used (if you want to learn more: redis.io/topics/faq)

comment How does vm.overcommit_memory work?
@MikhailMorfikov: In theory, I believe so, but who knows what these programs are doing. Would want to see a more controlled environment with a simple program that just allocates say a gig of ram via Malloc. And then run the test after rebooting between tests.

comment What is the maximum theoretical throughput of a NAS device to 100 workstations with 1Gb/sec connections?
Ya, just keep what TomTom said in mind, VDI is likely highballing it. But when you lack information, and you have the budget, better too much than too less.

comment iDRAC login loop
Also, if there are too many log in attempts with a false password, iDRACs will block people from logging without telling them for what seems to be an undocumented amount of time....

You could also assume their entire workstation is hosted on the SAN, and pretend you are building a Virtual Desktop Infrastructure (VDI) and use some estimators like blogs.citrix.com/2010/10/31/… .

comment Why is Router IP Address Repeated in Trace Command?
@FelixFrank: In addition to the routing table, capture captures with a tool like tcp might provide insight. In particular observe the IP header.
