9.1 iFolder Configuration
Ensure that you configure the iFolder store in the SAN storage.
9.2 Web Admin and Web Access Server
Configuration
Because the storage is SAN with Fibre Channel, data retrieval is faster and more requests can be
processed. This in turn increases the CPU load factor as the number of data synchronization requests
grow. For optimal performance, you should have separate Web Access and Web Admin servers.
9.3 Planning
To ensure that all servers are behind SAN and that cluster failover/failback is implemented, you
must deploy 2n servers, where n is the number of iFolder servers the organization is planning to
deploy in a multi-server environment. In this case, all the servers share the same storage array, with
different partitions enabling the cluster to be effective. This means that every iFolder server has a
backup node to support failover and failback and to provide high availability.
If hardware is a constraint, Apache virtual hosts can be leveraged, so that during a failover, the slave
runs along with another slave in virtual host mode behind Apache. The only drawback is
performance, because the Apache server must service twice the server load and number of user
requests, which is not recommended unless the deployment has comparatively few user requests.
9.4 Key Benefits
The key benefits of deploying the iFolder server in Fibre Channel or iSCSI are as follows:
This type of setup is beneficial in organizations that require high data availability and faster
response time.
The number of hits per second to the iFolder server through a browser and thick client is based
on the server processing capability and the network link. A Novell
limit the number of hits because it runs behind Apache.
A smaller backup window enables high data availability to the clients.
9.5 Scalability Parameters
The scalability parameters for deploying the iFolder server in fibre channel or iSCSI are as follows:
The server is scalable to 1000 users.
Data storage can scale to several terabytes of data.
The data transfer (synchronization of user data) rate can be 50 MB per hour per client.
