Scalability Parameters; Deployment Scenarios; Business Services With High Volatility - Novell IFOLDER 3.8 - DEPLOYMENT Deployment Manual

Ensure that each iFolder server has its own eDirectory replicas so that the authentication
happens locally instead of walking the eDirectory tree.
iFolder supports both secure and non-secure communication with the directory server. You can
choose any communication channel that you need. Ensure that the directory server is listening
on standard LDAP ports for secure and non-secure channels.

7.4 Scalability Parameters

The scalability parameters for a multi-server cluster deployment are as follows:
Scalable to 1000 simultaneous connections per master.
If a slave is included, see
"Multi-Server (Master-Slave) Deployment," on page 19
Over a million users can be provisioned in each master.
Each master server can store up to a terabyte of data.
The synchronization interval must be 5 minutes.

7.5 Deployment Scenarios

A multi-sever setup in a cluster environment is beneficial where high availability is needed and high
volatility is expected. The following deployment cases discuss how a multi-server (master-slave)
setup can be used for load balancing and data synchronization in an organization where
requirements are expected to increase for employee count, frequency of access, and high
availability.

7.5.1 Business Services with High Volatility

Consider a stock brokerage firm that has 10000 users and 100 relationship managers. The firm's
primary requirement is to have immediate data availability with a good response time. Over a period
of time, the number of users in the firm might increase. Under the current setup, the storage can be
increased dynamically, but the response time will continuously decline. With an iFolder cluster, the
physical server upgrade can be less painful with no downtime. Also, if the business grows at a
particular location and declines at another location, users can be migrated to another iFolder server
and the servers can be consolidated.
