Recondations for Server Hardware For Sage CRM

The following sections provide general recondations for Sage CRM installations, as well as specifications for large CRM installations.

General Recondations

We strongly recond using a level 5 RAID disk array system. The level 5 RAID allows you to swap out a faileddrive with minimal disruption to your production environment. The RAID disk array system also provides significantly better performance. Each supported server should have access to a high-speed modem (56 KB or more) for remote support and RAS. Each site must have adequate backup and recovery capabilities, for example DAT / DLT tape drives. We recond that you use an Uninterruptible Power Supply.

We strongly suggest that you have a "hot stand-by" system that has a backup database. This standby system should have a very similar configuration to the primary production system. The standby system can also be used for development and testing.

The amount of disk space required varies widely based on the number of customer records, archiving plans, and backup policies. The disk space can also vary widely based on the amount of information held for each customer. Therefore, it is important to try to estimate this prior to installation and purchase sufficient disk storage to allow for significant growth in the volume of data.

It is important to keep in mind what type of user will be working with the system. For example, 200 call center users use the system more intensively than 200 sales and marketing users.

Solo Installations

Regardless of number of users, every Solo CRM system should have a dedicated database server. The database is regularly usedfor heavier synchronization processes coming from Solo Clients.

Installations with over 50 Users

Servers	:	Split the Database server and Web server across two machines.
Memory	:	The amount of memory in the Database server should be no less than 50 percent of the anticipated database size after one year. Planning for a ratio of 75 percent provides additional performance and room for errors in the size estimate.
Processors	:	The processors in each of the machines should be high specification, for example 2.8 Ghz P4 Xeon.

Installations with over 100 Users

Servers	:	At a minimum, the Database server should be dual processor. Ideally both machines should be dual processor.
Memory	:	The amount of memory in the Database server should be no less than 50 percent of the anticipated database size after one year. Planning for a ratio of 75 percent provides additional performance and room for errors in the size estimate.
Processors	:	The processors in each of the machines should be high specification, for example 2.8 Ghz P4 Xeon.

Installations with Several Hundred Users

The specifications below assume that users are fairly interactive, for example, users working in a Call Center. Youmay get more users on a lower specification if the users are lower-usage users.

Servers	:	At a minimum, the Database server should be quad processor. Ideally both machines should be quad processor.
Memory	:	The amount of memory in the Database server should be no less than 50 percent of the anticipated database size after one year. Planning for a ratio of 75 percent provides additional performance and room for errors in the size estimate.
Processors	:	The processors in each of the machines should be high specification, for example 2.8 Ghz P4 Xeon.
