I currently have 4 web servers (Windows 2003) and 4 sql servers (SQL 2000)
and would like to consolidate these into an entry level SAN. As the web
servers are running the same IIS based applications, i'd like to cluster
these to use the centralised storage and likewise with the SQL servers. I
was thinking of something like a Dell/EMC AX100 solution or maybe the
AX-100i (although is iSCSI a reliable option for clustering IIS or SQL?).
Would people agree that this would be the way to go or would there be some
other recommendations? Storage use at the moment is around 3TB growing to
around 10TB in the next 3 years. What about backups for this amount of data.
It would be good to have the data mirrored across to another storage unit
(is this feasable?).
Any help or advice with this matter is appreciated as i'm new to SANs and
any recommended intoroductory reading would be great.
Thanks - Jules.

|||What sort of performance are you needing? If you need any kind of
performance considerations from this cluster, then I would not recommend the
AX100, and would recommend using a CX500 instead. Sure the CX500 costs
more, but you'll get more speed and reliability from it.
The AX100 is great for storage, and is a great backup to disk solution, but
for a SQL cluster, even though it could do it, would not do it well.

cost you a lot more as well.

|||So, the Clariion CX series will support Adaptive Copy, RDF/S and RDF/A?
If not, will the sancopy, mirrorview, and mirrorview/A support distanced or
stretch mirroring?
Again, if not, are we talking about degrees of distance, in which case it
would depend on this user's requirement of geographical separation? In
other words, you might have to go with the SYM DMX to get the distance, and
reduced latency, that your environment requires.

Clariion does support distance/stretched mirroring via Mirrorview.
MirrorView and MirrorView/A are similar to SRDF/S and SRDF/A
respectively. I don't believe Clariion has an Adaptive Copy equivilant,
but I'm not sure about that. As far as distance and latency, you
basically have the same set of obstacles to overcome with SRDF as you do
with MirrorView. Also, like the Symmetrix line, Clariions support
consistency groups.
Jon
|||With Sancopy / mirrorview / mirrorview/A, the Clariion is able to replicate
any distance the Symmetric can because the technology is control by FC-IP
routers, which transport FC over IP over any distance. I have assisted with
a Washington - Atlanta full sync mirror view connections, as well as New
York to LA. McData fibre channel IP routers handled the connections.
While the terms may be different, the technology is very similar. The only
real difference between the Symmetric and the Clariion is the Symmetric has
active / active FC ports, and the Clariion uses Active / Passive ports.

|||If you really need to expand the SAN up to 10GB, then you should have to
select at least CX300 or CX300i. The reasons are:
1. AX100/i does not support cascading storage.
2. By cascading up to 4 x CX300, you can have up to around 19GB for storage
space.
3. You still need a growth buffer, right?
For iSCSI, I consider that will not be a bad choice unless you have to
consider the performance difference between Gigabit Ethernet and 2GB FC.
However, in terms of unifying your network equipment to pure IP based, it
may be a good choice.
To choose between CX300/500, the only factor I consider is the total storage
size, since that the performance factor does not generate noticible
difference to me.
Considering iSCSI, I have implemented iSCSI-SQL server cluster solution for
testing and for customer production environment for few time already and
found no particular problem. The art is the OS and SQL level fine tuning,
instead of iSCSI. iSCSI itself, even using Microsoft iSCSI initiator, is a
very stable as I experienced.
