Here we discuss options on how to store your files with OpenAsset:

Local Disc Storage

Many OpenAsset servers use local file system storage for both the OpenAsset software and the file store. We believe it is vital to have some form of mirroring redundancy on the hard disks running both the Operating System, OpenAsset software and file stores. This might be through the use of RAID 1 or 5, and is most commonly a hardware based RAID solution.

Hard disk RAID redundancy does not remove the need for regular backups of the OpenAsset data but will reduce or eliminate downtime when hardware failures occur.
RAID for the purposes of improved disk access speed is not usually required (e.g. RAID 10).

Technologies – SAN, NAS, NetApp etc.

With some OpenAsset installations, the files aren't stored on the local disks but instead use networked storage technologies. OpenAsset can connect and use any form of storage that provides access via the Microsoft pioneered CIFS protocol. This includes most NAS and SAN products on the market.

Connections – Fibre Channel, iSCSI and Ethernet+TCP/IP

Web and file serving from OpenAsset is not very bandwidth intensive over a local LAN. Gigabit Ethernet is great but not required.
Some clients have the OpenAsset file store on a separate machine to the one running MySQL / Apache / Image processing. In these cases Gigabit Ethernet, Fibre Channel or iSCSI connection is preferred but normal 100Mbit Ethernet+TCP/IP is ok in some cases.

Secondary file stores

The OpenAsset web server is always only located in one office. All offices use this server via a web browser. We therefore only require one server on which to perform the initial install of OpenAsset.
However you can have multiple file stores. There is always one "Primary File Store" in the same office as the web server and database. The "Secondary File Stores" are then located in satellite offices. These secondary stores contain a complete copy of all files in the primary store.
If your inter-office link goes down the satellite office can still use the secondary file stores to print documents etc. InDesign and QuarkXPress link to the files in the file store and don't require the web server or database.
We don't advise that all offices need their own file store. We suggest starting out with a simple setup and adding secondary file stores retrospectively where required. This can be done months / years after the initial roll out on a needs basis.
There are multiple ways to setup file store replication, but the most common is to use DFS built into Windows Server.
