Download Items from Vault - Network utilization

Hello All

We are working in our environment to ingest all PSTs into enterprise vault. One question that came up which was bit tricky one to answer is "How much bandwidth will be consumed when users will try to download items from vault rather than accessing them locally on PST file"

I went through lot of documents but couldn't find answer for same.

Anyone who can assist in some kind of formula or rough figure?

The difficulty really comes from the fact that you don't have a baseline of how frequently those users are opening items in their PST file, it could be often, it could be never at all.

With a PST file ingestion, you will obviously see a large spike in bandwidth from the collector getting the PST files or the client uploading chunks, and then if you use Vault Cache and Virtual Vault you will then see a spike initially when users start to build the Vault Caches locally on their machine.

As tony pointed out, when yo have virtual vault, it will resemble a PST file anyway, so you will be doing most stuff locally anyway, but without that, you'd really have to enable Auditing to get some kind of idea how often archived items are being downloaded.

With a good bit of SQL logic, you can determine frequency and size of items being downloaded and do the math from there, , however i certainly don't know of any whitepapers or studies on how much network utilization will be taken up, especially since companies are so different, with the amount of employees, their retention policies and such

If you are using Vault Cache and Virtual Vault the network utilization will be negligible. 

Are you using VC and/or VV?

It really depends on the size of the item.  However I have never come across a case or issue where this has caused problems.  Usually the items ingested into vault for a start are no longer accessed on a regular basis, hence they have been vaulted in the first place.  You could also argue no more than if Outlook was not in cached mode as well.  If you use VV/VC as Tony states it would be negligible (depending on your settings and size of VC would determine how much data is kept in the VC) as this carries out a pre-emptive trawl and stores items offline before they are archived reducing or eliminating bandwidth requirements opening items.

We are using vault cache however in a restricted way - and we need to make decision if we want to enable for all users OR just keep it same since there won't be much impact on network.

Only concern with vault cache i can see is a. Performance on Workstation & b. Security concenrn since vault cache is just db extensioned PST files

What is the security concern?  Right now folks just have PST's on their machines so you will be no worse off then before, right?

Does Outlook run in cache mode?

agreed with tony, and as far as performance is concerned on the end users desktops, yeah they will see some initial network traffic, but it doesn't slow down outlook any, the worst performance impact you will see (and i've unfortunately seen this alot) is with Outlook Instant Search/WDS indexing as it takes up a ridiculous amount of CPU, but you can easily just disable that, and you would see the same performance if you had regular PST files indexed also.

Security concerns are same as they are with PST files basically, though vault cache adds another layer of encryption.

Plus users aren't familiar with this feature so that was concern - Wanted to keep minimum user work style change.

Enabling for lot of users at same time will cause some issues because they will expect it to be updated within same work day - However based on throttling parameters set on EV server their turn might not come (number of connection & max size of vault cache folder)

So the original question relates to this - Does enabling vault cache will give significant/noticeable improvement/drop in network usage in long run?

Ok I just want to address this but vault cache gives no additional protection over regular PST files, there is no encryption, you could just take all the VC files, rename them from MDC and DB to PST and open them in outlook

Another consideration is that once the initial Syncronization is done with VC, EV can be configured with preemptive updates to VC. So the EV client will copy data that is going to be archived from the Outlook Cache to the VC locally . This should reduce VC downloads to the desktop
