comment Can Dell Equallogic share a LUN that's not dirty for NTFS writes?
MarkM has laid out the main options for you in terms of getting that storage mounted and basically accessible but as far as I know, the storage doesn't have any "magic" to keep the filesystem "clean" with regard to multiple hosts doing writes and locking files independent of each other outside of a managed cluster scenario. In other words, it's down to OS and protocol whether access by multiple hosts can be done cleanly rather than storage.

comment How to keep load-balanced servers synced even with deleted files?
I am definitely a fan of NFS but keep in mind that while it consolidates everything in place, it does mean that all of your front-facing sites are dependent on that one shared copy as both a single point of failure and a single set of resources if performance is an issue.

no worries...once I saw janneb's answer, it was clear the answer was covered :)

comment Four disks - RAID 10 or two mirrored pairs?
I can't think of a compelling technical reason to split 4 disks into 2 mirrors (esp. just 2 mirrors and no spares). That said, there can always be reasons: a build standard you can't change or a requirement to physically isolate app/data from system disks or maybe even some customers (or devs) who want it like they want it and it's not possible or worth it to change their minds.

comment Four disks - RAID 10 or two mirrored pairs?
My .02...if the measurements show that there is no contention under a range of conditions from normal to peak, then mitigating a theoretical resource contention is worth about as much as bullspit as Matt points out. ;) So, unless there are other reason for splitting things out...

comment Why buy high end hardware firewalls?
I agree that legal action is pretty rare in my experience but having an ongoing relationship with the vendor and/or support organization can result in good leverage to resolve issues if things do go sideways. I generally think of it as "reaching out for help" but I've also seen it as "having somebody's desk to pound on" if there's a problem.

comment Tools for Remote Desktop with Relay feature
mRemote is convenient for me when I use a Windows desktop since I manage multiple servers and devices using RDP and ssh and it was nice to have everything in one place. I've also used royalTS and a plain, old duct-tape custom mmc with all my RDP connections saved.

comment Is there a limit that a folder can store how many files and folders?
good point re: db blobs. It may seem like a good idea occasionally but everybody regrets it sooner or later if there are many and/or large files. Let dbs do what they are good at and let filesystems be used for what they are good at...if needed, manage the layout on the filesystem and reference those locations in the db.

comment SAN typical MTBF
Those kinds of failures are seriously painful and I don't envy your situation. However, no SAN that's sold as fully redundant and highly available and has been installed and configured in that manner should be failing that often and that spectactularly (if at all). Cold comfort, I know, when you're living through that pain and hearing those kinds of explanations. :(

comment FATA disk performance for VMware
You have to use what you've got available. You're right that guest VM-based stats may not tell the whole story performance-wise as opposed to array stats. It isn't uncommon at all to measure performance using Windows and Linux OS-based tools and roll it up as you are thinking about doing. It is not a bad method...done carefully, it should represent fairly well what your environment's workload looks like. Ideally, array stats would offer another "whole system" view to keep in mind. Any chance of temp/eval licenses to look at thos array stats? ;)

comment FATA disk performance for VMware
FATA is ATA-based disk that can plug into a FC-backed enclosure...where supported, a cost-effective way to add relatively cheap disk to an enterprise disk array.

comment Netapp Filer - can I resize an aggregrate?
I believe this is technically inaccurate. Aggregates cannot be sized downwards. As this post and others have pointed out, aggregates can be grown on the fly.

comment Early signs of a bad sysadmin
Very good points. Some of those problems are infectious as well. Even if a "bad admin" finally moves on or is moved on or loses their credibility, their finger-pointing and "tear it all out" critiques can been like weeds taking root in the minds of management and whomever is left on a team. Kind of similar to the "say it 2 times and it must be true" syndrome.

comment Early signs of a bad sysadmin
It's surprising how much damage can be done in just a few months and how long it can take to set things right. Just think though...sometimes an admin like that can stay entrenched for years.

comment How do you physically transport your backup media?
You can only do what you can do...if your company can't or won't vault with a bonded offsite operation, it limits the possible solutions. I'll edit my answer above with some additional thoughts.

comment Running 1 DC physically and a second virtually
This can be a serious gotcha...it applies equally to any restore of a previous version of AD when there are 1 or more current/live DCs running but the ease of using VM snapshots as "safety nets" over the last few years has resulted in this previously somewhat rare issue cropping up more frequently.

comment An honest security ethics nondisclosure question I need help with
good points. Likewise, revealing that you are aware of the problems years later really opens you up to some uncomfortable questions if the discussion bubbles over into legal and business areas. It's unlikely that part of the agreement was that you'd keep "checking on them" for years to come.

comment Unable to delete locked page file on SAN
In the same vein, I experienced a recurring issue with VSP scratch files and NetBackup on a Windows client. Rebooting the client allowed deletion (not optimal for a production server) but just shutting down the NetBackup services did not. Investigating with Process Explorer revealed that the virus scanner had them locked and wouldn't let go so shutting down NetBackup services and all virus scanning processes freed the files for deletion. This was a better alternative than rebooting for us until we were able to work around the problem permanently.
