Subject: SUMMARY - Fiber Channel RAID adapters - Price/Availability
The answer is....... "42" (Deep Think)
.... the question : What is the meaning of life,(the universe and
everything)...etc.
Actually the reponses were excellent (see below), unfortunately what it
means is that I need to do a little more homework on this problem. Such as;
1) Do I need to be using v5.0a instead of v5.0 to get FC support in Tru64?
.... yes, you need V5.0A
2) If FC is supported, will it be FC/AL or Switched FC?
.... initially switched
.... FC-AL will be part of a NHD (New hardware delivery) release
(separate CD with extra functionality, not to be confused with
patches) in a couple of weeks
3) Do I really want a FC RAID controller mounted in the host or
could I get away with a FC/AL RAID controller in the storage
cabinet as I have now with UW SCSI RAID controllers (ala
Infortrend) and a FC Host Bus Adapter (arbitrated loop or
switched)?
.... there's the catch, as Alan puts it clearly in his response,
Compaq supports only StorageWorks products. It is up to 3rd
party vendors to commit to their products.
4) Will my "Third party" vendor assure me that it will work?
.... don't know, who is your 3rd party vendor ?? Ask for
REFERENCES !!!
>>> I would rather not give names at this point, let's see how
it comes together first.
5) SCSI-3 / Ultra160 - Who knows??? (Don't get me started!)
.... the issue round SCSI-3, etc. is that basically everyone
does something, but few people do the same thing. One of the
things you should be aware of is that with V5.x the SCSI-2
addressing limitation is gone (you can now actually use > 8 SCSI
ids on a wide bus, something that was impossible in V4.x & was
strongly limited the use of Fibrechannel stuff in V4.0F)
