Enterprise Vault Design

[Ronen_Tzimbel]

Hello,

We have 5 branch site with 5 Exchange server 2007

the size of the database is  each exchange server 300-400 giga.
 
I need to know if  it possible to archive all of the Exchange server with 1 Enterprise vault (put in DataCenter Site) ?
the Bandwidth Between Branch site is 4 MB/s (500KB\s)

Many Thanks Ronen

There are a lot more considerations to take in to account here.

However the simple answer is yes.

The more detailed answer might be no.

You should involve a SYMC partner or Professional Services.

What is the latency like?

The key elements to consider are:

     Daily archive volume (# of messages per user * # of users) and available bandwidth.  The size of the Exchange db is essentially irrelevent. 

A 4MB pipe could transmit a maximum of 19K items per hour (average size of 100KB).   You should probably expect half of that (without further testing).   If we add in the following assumptions:

      - 25 emails per user per day

      - 4 hour archiving window

 You could accomodate ~1500 users per remote site.    With 5 sites and a max of 1500 users you would be at the top end of a single server capacity.  If there are fewer users (less volume) per site you should be able to accomplish your goal.

I would also recommend that you consider use separate vault stores for to separate exchange locations so that  can easily expand to a second server to split the load in the future.

Thanks maxwits,

Is It Possible to archive 150 Users with 150 Giga DataBase (Over the WAN) in Day one.

I have 48 hour archiving window for that (Saturday- Sunday) and 6 hour (Monday- Friday)
I Dont know  How long its take to archive ?
I afraid that it`s take a long of time

thats all a load of hog wash.  Yes it could, but latency here is the big killer.  for each message archived, you will have around 11 mapi calls so you can have a 100MB pipe, but a latency of 200 ms but that would take 2 seconds just to do the mapi calls per message..... this has noting to do with just bandwidth.

You need to contact a professional here if you want this working properly. Contact a Symantec Partner or Symantec PS.

Wayne,

the latency is 40-50 ms .
