All total we have 2 full 42U racks with one rack of high density gear and the other rack of lower density storage gear. Main NAS is about 80TB. All running CentOS 5 or 6 or Fedora 19 (or esx with one windows server for the manager - blech!)<br>
<br></div>And I am the only admin. Plus I have the student lab room with an amorphous hodgepodge of crap running win7 or Linux (Ubuntu or Fedora) and lousy bandwidth back to the NAS for /home mounts.<br></div><div class="gmail_extra">

Ah, I didn't realize you were at Emory.<br>
No, I'm at UA (University of Alabama main campus) in Tuscaloosa. I'm the primary Systems Engineer for Linux Systems, and the backup guy for virtualization. Luckily, the HPC stuff gets managed by someone else for the most part.<br>
How big of a deployment do you have?<br>
We've got 250+ datacenter Linux systems, and another big chunk for HPC/research.<br>
Most of the datacenter stuff runs SLES, with a handful of other distros thrown in the mix because of vendor requirements.<br>

I forgot you were at UaB (I think) and that kind of environment (like mine at Emory) provides rather, um, unique problems.<br>

The problem we have is that we end up acting as more a central hosting provider at times... we have so many disjointed areas around campus doing things on their own...they go and have someone develop a site for them, THEN put in the request for us to host it. We don't have a central web development team, although we have pockets of web developers who know what they are doing, and for the most part, they run critical sites. Right now, we have 500+ WordPress sites, and one of our Security employees spends a good portion of his time trying to get people to patch their WordPress before it gets hacked, etc...<br>
Yay.<br>

I'm constantly arguing with boneheaded web developers who go and do their development on the latest bleeding-edge release of Ubuntu, Fedora, or OpenSUSE on a VM on their workstations, then expect me to upgrade the PHP on our SLES servers to that version on their test VM.<br>
At this point, I have to point out that we provide test/dev space on an identical server to production for a reason...and then they stomp and rant and rave, and I have to escalate to management and let them tell them "not just no, but hell no" on pulling in unsupported PHP packages or setting them up a special Debuntu VM for their site.<br>
Bleeding edge releases + web developers = a deadly combination and a huge security problem.<br>
Allen B.<br>
<br>
That's always an issue. I changed our HPC stack from CentOS to Fedora to avoid a mess of broken lib issues. At least these don't see public traffic. PHP is scary enough without running the latest developer versions on a public site.<br>
<br>
I call those developers "lazy and soon to be unemployed". Provide them a mirror environment of the production realm to develop in and if they can't make it work, they can explain whey the design needs to change or they can work somewhere else.<br>
