comment Premature SMB/CIFS Session Close (System error 1312) with Password on SMBv2
I'm not putting this in an answer because it's a cop-out, but this problem is specific enough that you should probably open a case with Netapp.

comment Access a share on a server using another servername
You can make all the old top level folders top level folders on the new storage, is what I'm saying. So if your old storage included \\B\sales, you could create a "sales" share on \\A\ and make the old IP address for B point to it.

Also, if it's a double hop issue, you might want to check this link: ravichaganti.com/blog/…

Is the Netapp running CDOT or 7-mode?

comment RAID 10: Does it impact performance if I have 24 small drives in Raid10 vs. 4 larger drives?
I'm not editing my answer, it's clear what I was talking about.

@Tomtom, I was specifically talking about streaming IO. I went on to describe their speed compared to seeking spindles later.

Murphy's law, @warren :) If I reverse the standard, they'll drift the other way.

comment SSDs for MS SQL Server 2008: slc or mlc: what is expected life for mlc?
No it doesn't. The only answer that matters is that no matter what you do on your server, you have a warranty and the vendor will replace a failed disk.

comment Checking fiber cables for light without risking my eyes
I'm probably in a minority- I have a cheap-ass phone I don't give a damn about. If it stops being able to see light from cables, I'll have it replaced. It's still cheaper than a new light tester or a new set of eyes.

You should have a serial port somewhere on your supervisor.

I've seen the datacenter manager do it ;)

comment IBM Fiber Storage
IBM had a specific set of hard drives that were sold for this model. Not all IBM drives are certified for use in all IBM storage. This system is so old that the lists of acceptable part numbers are no longer online, so I can't help you find them.

comment IBM Fiber Storage
The disks are not the ones that IBM sold with that controller, which is why they're uncertified.

comment Long running VMWare snapshots are bad… but what about VMDKs on a ZFS\LVM snapshot?
Assuming block based storage (iSCSI or FC LUNs), then snapshots are on the hardware and don't care whether the ones and zeros you write are a VMDK or a boot sector. If it's NFS, then snapshots will likely be more granular. The issues about snapshots depend on the method being considered. Copy-on-write snaps on a LUN, for example, will begin to degrade performance if you have too many snapshots, but not based on how long you keep them.

comment How should I set up my Fibre Channel (FC) network?
This was a Q&A- not a real question. There was an initiative a while ago to make canon answers to common questions. I also wrote the answer :)

comment Does AIX support Advanced Format (4k sector size) SAN LUNs?
Using 512B when your storage works in 4k blocks means that any small IO might waste as much as three quarters of the block and do four times as many IOs as needed. That said, people tend to underestimate exactly how much of their IO is literally single block non-contiguous. Even random IO databases tend to do IO in clumps. Many small random clumps, but not always single 512B transactions.

I'll ping you on the mailing list.

comment Joining a NetApp to a domain on a Read Only Domain Controller
I think you can- if it's the same vlan, that means it's not on the same interface: if you did a vlan create interface0 310 followed by another vlan create interface0 310, I think it would fail. If the second one was on another interface, though, that would be fine. And then you could assign interface1-310 to the nonprod IPSpace temporarily
