Check out the McData web site for more information. There are two press releases that seem to backup what EMC says.

Percy,
No company left the FibreAlliance. This was a mis-interpretation of only one reporter. Note that no other press reported the same story. The FibreAlliance is focused on managing SANs.
The OSFI is focused on working on interoperability of the protocol for switches. Specifically, how do two different vendors switches talk to each other over eports.
All the work that the FibreAlliance does is submitted to standards bodies (ANSI, IETF, DMTF, etc). So there is no reason that they can be considered proprietary. For example, the MIB is currently a proposed draft in IETF and changes to the protocols have been submitted to ANSI.
The quote below from Roger (Reich) was mis-quoted out of context. Roger even sent in a letter to unigram about this and it was published. As to all the groups working on standards, it turns out that we are all working together very well. The FibreAlliance is focused on SAN management at the lower levels of protocols, APIs and MIBs.
It turns out the SNIA has adopted the MIB that we submitted to IETF and have proposed changes which have been incorporated into it. Finally, I have seen lots of presentations by analysts about NAS and SAN and what is stated below is really focused on the point they make of where do NAS and SAN meet. If you need to have file sharing, then use NAS but even the NAS server will need the benefits of SAN (connectivity, distance, scaleability, etc). So the analysts position NAS as using SAN on their backend. There are still, and will continue to be, a large installed set of application that do not use NAS and they will use SAN directly.

What's the answer? Thanks, Percy

Any comment ? Patrice
EMC's Fibre Alliance Woes and the state of SAN Interoperability On 7/23 Jo Maitland announced in UNIGRAM, that more than half of the
Fibre Channel switch manufacturers (McData, Brocade, Ancor, Gadzoox and Vixel)
defected from EMC's Fibre Alliance, "fed-up with its slow pace on standardization". These 5 vendors have created their own,
independent
group, (the Open Standards Fabric Initiative - OSFI) charged with settings standards of interoperability between their own products and between
their products and third party products.
Key points:
- Standards exist for interoperability between switches, and third
party products, but each vendor was using their own interpretation of
those
standards. This led to a lack of interoperability between different manufacturers switch products and the need for customers to purchase
proprietary SAN solutions - something they are not interested in doing. This also led to lack of plug-and-play interoperability between switches and third party products (such as the HBAs needed in servers to connect
to
the SAN) - in turn forcing vendors of SANs to go through exhaustive interoperability testing every time a new product revision was released or a new product line was added to their suite of SAN products.
- EMC set up the Fibre Alliance in February with great fanfare,
splitting off from the SNIA to develop interoperability between components. Notably absent from the group were any other storage vendors such as IBM or Hitachi. As a result it was seen by many in the industry as a way for EMC to force it's own standards on the rest of the Fibre and SAN community. An effort
that has obviously failed - at least for now.
- Despite the fact that the OSFI has stated that it is a subgroup
within the FibreAlliance, EMC has stated that they will monitor the group
to
see if their work conflicts with what the Fibre Alliance is doing - in
other
words EMC will do what they're doing, without input or feedback from the OSFI,
leading yet again to dual (and dueling!) standards. An indication of
this is contained with the report: "One analyst on the call said that working on
device level interoperability is fine but without an overall
framework
for managing those devices, the storage area network is still way off. A
spokesperson for McData, a member of OSFI said, "We have to crawl before we can walk." "
- A third group working on standards is the SNIA (Storage Network
Industry Association) with over 100 members. A quote from the SNIA and from a
member of the OSFI sums up the situation with multiple standards committees
working on the same issues but in opposite directions. SNIA chairman, Roger Reich, director of Compaq's network storage division said of the new group: "I don't know where they are going or what they are doing, but if they need
backing in the form of money or talent we would be happy to speak to
them." He added that the Fibre Alliance was a closed, profit-making group with a different agenda to the SNIA. In response to Reich, Greg Reyes, CEO
of
Brocade and a member of the OSFI said: "We are not interested in his
offer."
Summary
- Despite their protestations to the contrary, EMC is
proprietary, will
continue to be proprietary and does not wish to work on a global
scale
with other vendors to open up interoperability of servers, storage
devices
and interconnect products such as switches, hubs and HBAs. Customer purchasing EMC storage devices or SAN implementations will be locking
themselves
into the high price leader and into a proprietary solution. 2. This lends further credence to ****** stated vision (backed up by
analysts) of NAS as the "Intelligent Gateway" to the SAN, and that
NAS
should be implemented today with an eye toward tomorrows SAN implementation (i.e. SAN should not be implemented today). Install SAN today at
your
own risk, if for no other reason than a lack of standards and a lack of
a
current methodology of moving toward a single set of globally
accepted
standards.
