Riverbed acceleration applicances

  Asked By: Ruchir    Date: May 31    Category: MOSS    Views: 1150

Anyone here using Riverbed Accelerator appliances in conjunction with Sharepoint
v2 and/or MOSS 2007? I've seen some rather suprising results, and wanted to get
any opinions from experienced users.

Well, we sell Riverbed and I think its fantastic - it is like turning a
2Mb pipe into a 100Mb connection for pure HTTP and the results aren't
much different for word documents.

If you have any questions, let me know and I can ask someone internally
who knows more about it than I.

Do you have any metrics that indicate performance gains? In
particular, we're looking at using a MOSS 2007 web app to facilitate this file
transfer service. Evidently one of our teams did a 20MB file transfer session
with MOSS, SPS, FTP, and a file share, and MOSS came out ahead. Any idea why
MOSS would win over straight file shares? I don't know too much about the
differences between WEBDAV and straight SMB transfers.

We use Juniper WXC acceleration devices and we think they are great.
Overall we are averaging about 85% reduction of HTTP traffic. This
will go down with document transfers for sharepoint as word docs with
embedded pictures do not reduce as well as jpegs are already
(i evaluated the riverbed devices last year but we ended up going
with the Juniper WXC units instead. N.B. these were previously called
peribit devices). We have about 50 of the Juniper WX devices deployed
across our WAN (6500 staff, 65 sites globally, head office in Sydney)

In fact over the last 2 weeks I've been doing a lot of testing on the
benefits of the acceleration devices compared with a straight network
link and doing this at various bandwidth and latency settings (eg
256k, 512k, 1024k @ 100ms and 300ms latency). I use a product called
a network nightmare to do the wan simulations (costs about US$1000
well worth the investment to reproduce your slow wan links in a lab
environment). We're trying to determine what link speed we need to
make our users experience of MOSS from remote site good/acceptable.

On a standard link with no compression I found that the document
uploads using the multi upload feature are closer to wire speed
(average 458kbps) than using the standard document upload. Downloads
were close to wire speed. (eg download a 52MB xls with download at
476kpbs on 512kbps link at 100ms latency.) Standard document upload
on the same link only averages 265kbps.

Now the same 52mb xls (lots of text so it will reduce really well) on
the same link 512kbps/100ms wtih juniper WXC after the juniper disk
cache has been flushed.
standard upload @ 1453kbps, multi-upload @ 1198kbps and download @

We also found that on the same link (512kbps/100ms) that browse
speeds to doc libraries, task lists,etc are at the average of the 1
second mark. This is down from 2 to 4 seconds on the same link
without the Juniper WXC.

I hope that this info is helpful.

I would think that some sort of network acceleration device is almost
mandatory for doing a centralised or regionalised MOSS deployment
model these days. Plus these network accelerators help just about
every kind of traffic not just sharepoint.

Basically, what I have for you is a screenshot from Zycko's
(www.zycko.com) own internal riverbed implementation for their
sharepoint connection - it shows about 80% reduction in traffic for http
and up to 97% reduction for file transfers and as it is from a real
implementation and you'll also see what its doing with the other

I know that our IT department tested the Riverbed acceleration application
but don't exactly what the results were. I'd be interested in hearing what
your surprising results were. In the meantime our IT group is looking at
other acceleration applications.

I have tried just the server name, and also the
domain name. I followed your instructions below and they completed
successfully (The mail seems to have queued successfully).
However, I did not actually receive the test email in my Exchange
mailbox - I also tried sending to just a regular email address (not
Exchange) - no luck there either.

Additionally, this is the error we receive if we try to add a user:

"The following users do not have e-mail addresses specified:
[username]. Alerts have been created successfully but these
users will not receive e-mail notifications until valid e-mail
addresses have been provided" Then there is a link to "Set my e-mail
address..." And yet, if you click there, it only gives a link to
attach a file.

Any ideas?
