This is so awesome I would retweet it twice if I could!

CS 6.0.2. It has a fix for the 2GB quicktime render issue.

A Small Tree gigabit port in a Thundebolt box did much much better. It played more like 10Gb. There was still some tiering of the IO, but rather than 2 or 3 4MB IOs before dropping back to 8k, it would do dozens. 80% or more were 4MB and the video played well.
One thing I’ve noticed is that Premiere seems to drop frames on playback, but they don’t stop. In fact, you wouldn’t know they did it unless you had the frame drop monitor enabled. I’ve got a bunch of adobe debug stuff turned on.

[Alex Gerulaitis] “[Tom Elgin] “In a SAN, devices are identified by their WWN.”
I don’t believe that’s the case. WWN is used in Fibre Channel, ATA, SAS. In themselves, those aren’t SANs.”
The semantics involved in all this are ugly. People regularly call our NAS offering a SAN.
FIbre Channel, GSN, iSCSI, and AOE all offer “SAN”. They are storage networks. Xsan, CXFS, MetaSAN, and FibreJet are all products that offer gatekeeping/sharing capability on your SAN. In and of themselves, they are not SANS.Steve Modica

[Tom Elgin] “SCSI
iSCSI
Fibre Channel
SAS”SCSI == Small Computer Systems Interface
iSCSI == Internet Small Computer Systems interface (SCSI being sent over a TCP/IP network)
Fibre Channel (intentionally misspelled to differentiate from “fiber” as in ethernet fiber) == A special super awesome layers 1-3 designed to move SCSI commands better than IP.
SAS == Serial attached scsi. (So you don’t have to have big fat 50 pin centronix connectors anymore)AOE == ata over ethernet. Unlike Fibre Channel (the most expensive protocol over the most expensive network) they attempted to make something that was the cheapest storage protocol over the cheapest network.
FCoE == Fibre channel protocol running over layer 1 and 2 of eithernet with a special layer 3. (so there’s no TCP involved). We have these drivers now and expect targets next quarter.

I went back and read this a couple of times to understand what’s being asked. A “server” on a SAN network would usually be a metadata server.
The closest I could come would be “how do iSCSI clients (which could be interpreted as part of a SAN) find their iSCSI targets (which could be interpreted as “servers”). In that case, they usually use isns (internet storage name service). Several vendors support this, but not all vendors. In most cases, people just “know” the ip address. FCoE does broadcast discovery. One of the interesting things about FCoE is it just finds and mounts everything 🙂 So you need to segment things off with zoning. That’s just the way it’s done.

Someone told me we’d have our new tbolt product on the website today.
