So far my Aras knowledge tells me only one vault can work on one specific time on Aras platform, that means Aras only get files of the vault which is setted as default vault out.
Can Aras get files from the different vaults at the same time? For example is file1 and file2 are stored in vaultA and vaultB, could Aras can get file1 and file2 out at the same time?
If Aras can, how to do?

Hello Robin,
The Data Model behind Files and Vaulting allows multiple Vaults, and Files can be located in any Vault, but only one vault at a time. Call this Distributed Vaulting. If you look at the ItemType definitions, the FIle ItemType has a RelationshipType named Located, which has the Vault ItemType as the related ItemType. This relationship currently has the MAX_OCCURS = 1 in a standard installation. This means that any file can be in one Vault at a time, but you can configure dozens of Vaults.
Note: When the client is trying to interact with Vaults, the behavior is: (1) on CheckIn, the File is uploaded to the VaultServer that is the users "default" Vault. Default Vault is a setting on the User ItemType. Users do not have to think about which Vault to use, it is automatic. (2) on Viewing or Checkout, the Client code is looking at the Located Relationship under the File, and retrieves the File from the correct VaultServer. This is also transparent to the end-user. In this way, you can organize your users such that they are directed to local VaultServer's for most transactions, but they are always able to view Files from any Vault (without having to think about where the Vaults are located). This is Distributed Vaulting; the Files are distributed around your network to best balance storage and network traffic. You can of course have unlimited number of VautlServers with this configuration.
I am working on a Package this month that adds Replicated Vaulting. In this case, a single File can be stored in multiple Vaults simulataneously, with many different user definable rules for when should Files be moved or copied between the Vaults. For very large deployments (multple continents) sometimes you want the same File stored in multiple Vaults, so that it is "network-close" for users in 2 countries for fast viewing. We've got several replication modes: OnDemand, Scheduled, and Event Driven (like a Lifecycle promotion). The Replicated Vault Server prototype is working well, and now just needs some final testing and finishing touches before we can package and distribute.

Hello Peter, given the date of this post from June of 2009 I am guessing the Replicated Vaulting package is available. If so, can you point me toward where to find it? I am working on an issue with our customer in Bangalore where their remote sites are having a timing issue accessing Document Items which are associated with very large files (5 Mb, ish, and greater). Smaller files function, and all files work at the site local to the Vault server. I suspect they would benefit from having the large files replicated in both locations. Feel free to correct me, if there are other issues I should look for, but I can experiment with this in the mean time. I am also opening the overall issue with support as it is causing them some real difficulties. I will also post greater details in a separate forum post, but I went searching for this at the start as I vaguely remember us discussing distributed / replicated vaults in the past (very vaguely).

Mark,
You probably found the replication examples in the solutions area. If not: http://www.aras.com/communityprojects/?projectid=E93237D8AE894D1D88BD1DFCF8804F84
