IBM have not yet officially announced the exact release date of their next Operating System to replace V5R3.
Rumour has it that this new version, tipped to be called i5/OS V5R4 will be released in the first quarter of 2006.
Some of the new features that are believed to be included are:
- RAID 6 – in the event of a disaster this algorithm can cater for the loss of 2 disks in a RAID set and still recover the lost data.
- SCSI Attach IXA Adapters – a direct SCSI attach to the xSeries means you will not need to use a HSL link and adapter card in an external xSeries, as is used now.
- IPv6 – using different IP addressing methods, giving you use of more IP addresses and more security.
