Top Ten Reasons to Consolidate Top Ten Reasons to Consolidate LotusLotusWorkloads on Workloads on

IBM eServerIBM eServer iSeries iSeries and eServer i5 and eServer i5

VS

Run multiple Domino partitions on a single server safely and reliably - Start and stop partitions independently of each other.

Increase utilization of your expensive resources – don’t let memory, disk and processor cycles go idle. Share them among all Domino partitions

May reduce Administrator hassle! Maintain a single copy of both Domino and of the operating system on your iSeries server.

I5/OS subsystems isolate each Domino partition workload from being impacted by other partitions.

All Domino partitions share the same copy of Domino.

Domino for iSeries software can scale to support 90%+ CPU utilitization.*

Significantly reduce Domino maintenance time compared to multiple-copy server farm approach.

Reduce time spent administering security patches

Simplify DASD. On an iSeries server, disk is treated like one big “C:Drive” – spanning volumes automatically using a round robin technique to balance data

More disk arms can mean faster performance

Regular “defrag” is not required on iSeries disk storage

Hot spots of data are relocated to less busy drives automatically

iSeries

Improve availability - Automatically monitor the status of each Domino partition with the built-in Domino for iSeries “Watchdog” program

The Watchdog job will automatically restart a Domino partition that experiences problems -- without affecting other active Domino partitions

Single, consistent, system-wide security covering all objects

Object-based design not susceptible to viruses or tampering – “data’ objects can not masquerade as programs
