FROM THE NETWORK CORE TO THE NETWORK EDGE
Traffic management becomes critical as your network
infrastructure expands to support different types of traffic and
users. Most traffic management solutions have serious
limitations: too expensive, difficult to use, and overly taxing
on bandwidth. However ProCurve Networking by HP addresses these
requirements, overcomes the limitations of other solutions, and
gives you valuable insight into LAN performance. Click here to

SPYWARE SHOOTOUT
Need to defend your network from spyware? Lots of tools and
software have hit the market recently, and network executives
are left to decide which weapon works best. Our Spyware Shootout
2005 suggests the gateway approach might be the best starting
point but is it a long-term strategy? Click here for more:

Today's focus: Want to know how to create a $400 SAN?
By Mike Karp
It turns out that there may be something pretty useful in store
(sorry about the pun... but only a little) for smaller
businesses in the area of networked storage. Equally important,
it may have some profound implications for remote offices in the
very near future, and for enterprise storage applications not
long after that. Let me tell you about something I have recently
found. For about a month now I've been playing with a device in
my home office that gives me a $400 storage-area network.
Really? Really.
First, let's calibrate our expectations. What I've got running
is certainly not a high performance environment such as what I
would see from a SAN running a McDATA switch and some HP arrays,
for example, but then what I am running also costs a fraction of
1% of such SANs. What I do have is a virtualized storage
environment spread over two devices that gives me mirrored
storage accessible from any of the nodes on my home office
network and which operates at the bandwidth capacity of my home
office LAN.
Netgear, probably best known as a provider of home networking
gear such as wireless routers, has a SAN appliance (the
MicroSAN) that costs $150. Put a couple of drives in there - in
my case two Seagate 250G byte 7200 RPM drives (cost, $235 off
the Internet), connect it to my existing Ethernet router, and I
now have a quarter-terabyte of mirrored, sharable storage.
A piece of software called Local Storage Manager gives me the
ability to add and reduce capacity to the storage pool, mirror
partitions, and perform other basic management functions. I've
had multiple applications access the same file, including
streaming video to several clients, all hassle-free.
Local Storage Manager actually comes from Zetera, an Irvine,
Calif.-based start-up that provides Netgear with an appliance
the size of a small toaster. With a little bit of imagination,
the heat sinks on the top even make the device look like a
toaster. I'm now prejudiced, I guess. I've used the toaster as
my metaphor for an appliance for years. Appliances after all
should be easy to install (15 minutes maximum installation time
- otherwise, as far as I'm concerned, it's just a bundle), and
easy to operate. Looks like Zetera has gone me one better, and
turned my metaphor into reality.
This particular configuration is really intended for home use -
probably for home networks where families want to share TiVo
data, pictures, videos and so forth. Not unexpectedly then, the
device has some limitations for business environments. It cannot
co-exist with my Cisco VPN, for example, which steps on the
Zetera virtualization software. The Zetera folks tell me that
the office version (likely to manage many more than the two
disks in my early, home version) will have this capability along
with additional management capabilities. Zetera declined to
publicly say when the office version will be released.
This is all pretty interesting stuff. Zetera has produced what
is essentially a switchless SAN, or if you prefer,
"controller-less" IP storage. Theoretically, this should be able
to scale well into the range where it becomes attractive for
inclusion for companies building systems for enterprise storage.
It will be interesting to see where this goes. I'll keep you
informed.

IS IT THE NETWORK OR THE STORAGE THAT'S THE PROBLEM?
Midsize and larger businesses often find their IT topology has
become a complex mix of servers, networks and storage systems.
Many of these companies also route long-haul traffic over
fiber-based networks - metropolitan-area networks, WANs and
private optical networks. Who's responsible when a
storage-related problem occurs on a fiber network? For more,
