Memory

The amount of RAM needed increases linearly with the number of users connected to the server. Users are typically Power Users or Typical Users. Citrix recommends an additional 8MB for each Power User and 4MB of RAM for each Typical User. To do the math for a Windows 2000 Server with MetaFrame XP having eight Power Users and seven Typical Users, the equation would look something like this: 256MB + 128MB + (8 × 8) + (7 × 4) = 476MB. That's 256MB required for Windows 2000, 128MB required for MetaFrame XP and Citrix Management Console, 64MB recommended for the eight Power Users and 28MB recommended for the seven Typical Users.

MetaFrame XP

The next platform release for Citrix and is optimized for use with advanced Windows platforms, and tuned specifically for Internet use. This new architecture should allow Citrix to deploy any application, to any device, over any connection, with a highly competitive power and flexibility. XPa and XPe versions are available.

Metrics

Metrics are the measurable units that Resource Manager monitors. Each component or object has a set of metrics. Each metric has a definable set of thresholds or limits that describe normal operation. For management and users to buy into server-based computing, they must feel as if they are running their applications from their own desktop machine. Be sure you know what the default metrics are, what they monitor and what it they could be telling you about your server.

Microsoft Management Console (MMC)

The MMC provides a standardized interface for using administrative tools and utilities. The management applications contained in an MMC are called Snap-ins, and custom MMCs hold the Snap-ins required to perform specific tasks. Custom consoles can be saved as files with the .msc file extension. The MMC was first introduced with NT Option Pack. Using the MMC leverages the familiarity you have with the other snap-ins available within MMC, such as SQL Server 7 and Internet Information Server 4. With the MMC, all your administrative tasks can be done in one place. In Windows 2000, most of the system management tools have been centralized within the MMC.

Mixed mode

To support backward compatibility in a MetaFrame 1.8 server farm environment, mixed mode operation can be enabled. Although recommended only as a migration or temporary option, it does offer additional services and capabilities to administrators. Once MetaFrame XP is operating in mixed mode, the ICA browser service is enabled on all servers in the farm.

Multiple farms

Based upon the business requirements of organizations, some implementations require the use of multiple farms. Although this adds an additional level of complexity to an environment, it also comes with its own set of benefits as well. Benefits for using multiple MetaFrame XP farms include decentralized administration; minimized network traffic; minimized security risks associated with network traffic and traversal of firewalls for intrafarm communication; data store replication is not required; and segmented licensing-the ability to license farms separately versus one large pool.
