Q&A: Windows Storage Server
Microsoft's Zane Adams recently discussed the growing potential for Windows Storage Server with Senior Editor Keith Ward.
Microsoft released Windows Storage Server last September. WSS, available
only through third-party storage hardware vendors, replaced three-year-old
Windows Powered Network Attached Storage. Zane Adam, director of product
management and marketing for Microsoft's enterprise storage division,
recently talked to MCP Magazine about WSS.
Q: How stable is WSS? Have you encountered many bugs in
the product since the September launch?
It's been stable. Absolutely no issues, because its core function is
file and print. It's been optimized and tested for that, and we've optimized
it to each hardware [solution] with our partners. More and more mission-critical
data is going on it. I've seen customers with10-15 terabyte boxes and
higher running for a long, long time.
Q: Is WSS an evolutionary or revolutionary step up from
There's a lot of new technologies from when it was Windows NAS. It moved
from the Windows 2000 Server kernel to the Windows Server 2003 kernel.
We integrated functionality like Volume Shadow Copy Service, Virtual Disk
Service and 8-node clustering.
WSS is part of the Windows Server family. We take advantage of everything
we want from the platform and build on top of it. We tweak it and optimize
it, we add [WSS-specific technology] like Web UI for remote management,
and Storage Manager.
We disable services not needed for a dedicated file-and-print server.
We lock it down. For instance, you cannot locally install SQL and Exchange,
or make it an AD [Active Directory] server.
Q: The Virtual Disk Service (VDS) hasn't gotten much mainstream
press attention. What benefit will it have for administrators?
[Imagine you're a network administrator] with SANs [storage area networks]
from two different vendors. You have WSS, with five [storage boxes] attached
to each one of them, acting as your gateways. Today, without VDS, if you
have to do LUN management, like expand or shrink LUNs, you have to go
to vendor A's application and then mount LUNs on each of the storage servers
attached to that LUN. Then, when you're done with that, you go to the
other one and do the same. You have to do it with two different applications
and have to learn both of them.
But if the SAN vendor supports VDS, like most big ones do, you sit on
one of the machines with WSS, and attach to the "A" SAN. From
that storage server, you can mount LUNs on all five of those boxes attached
to Vendor A's SAN, without even firing up the application, and do the
LUN management. From the same machine, you can also traverse and do the
LUN management for the others.
Administrative costs of managing storage goes down. Suppose you have
SQL with three or four terabytes, and you need to expand the LUN; this
thing could save you hours, because it can automate that process.
