The advantages of virtualization include the following:
 

• You get more out of your existing resources. Pool common infrastructure resources and break the legacy “one application to one server” model with server consolidation.

• You can reduce datacenter costs by reducing your physical infrastructure and improving your server to admin ratio. Fewer servers and related IT hardware means reduced real estate and reduced power and cooling requirements. With better management tools, you can improve your server to admin ratio so personnel requirements are reduced.

• You can increase the availability of hardware and applications for improved business continuity.

• Securely back up and migrate entire virtual environments with no service interruptions. Eliminate planned downtime and recover immediately from unplanned issues.

• Gain operational flexibility. Respond to market changes with dynamic resource management, faster server provisioning, and improved application deployment.

The disadvantages of virtualization include the following:

• Virtualization adds overhead to the CPU, memory, IO, and network.

• Virtualization adds an additional layer to the hardware and software stack. Therefore, additional complexity is introduced in the following circumstances:

In Baan IV, users define series and numbers in the Maintain First Free Numbers (tcmcs0147m000) session. In the Type of Number field, users must select the type of documents for which the series will be used. The generated document numbers are always numeric and can consist of up to six characters.

In LN, users must define number groups in the Number Groups (tcmcs0151m000) session and then in the First Free Numbers (tcmcs0150m000) session, define the series and numbers of each number group. Users assign the number groups to various purposes in the corresponding sessions. For example, in the Sales Order Parameters (tdsls0100s400) session, users can select the number group for sales orders and sales schedules. In the Sales Offices (tdsls0512m000) session, users can then select a series of that number group for the sales orders generated by a specific sales office. As the series codes can be alphanumeric, the generated document numbers can be alphanumeric and they can consist of up to nine characters.

In general, you can enter a different series in the order field if you have an available series.

To add a new series, find the appropriate group in the First Free Number session, and add a new series and first free number (usually 1).

In Baan IV, go to the Maintain First Free Numbers Session (under Common, Tables, Maintain Logistics Tables, Maintenance 1). Groups are easily identified (e.g., Purchase Order, Sales Order, etc.).

In Baan V, go to the First Free Number Session (under Common Data, Tables, Logistics). There are number groups (e.g., 570 may be for Purchase Orders, 650 may be for Sales Orders, etc.).

In LN, go to the First Free Number Session (tcmcs0150m000 – it is in different places in the menu under different Feature Packs). There are number groups (e.g., 210 may be for Purchase Orders, 310 may be for Sales Orders, etc.).
