It wasn’t long ago that Red Hat and Microsoft released statements that they would no longer support Itanium (with Red Hat Enterprise Linux and Windows respectively). Now Canonical has announced that Ubuntu 10.04 LTS (Long Term Support) will be the last supported Ubuntu on not only Itanium, but Sparc as well.
Itanium has thus lost three major operating systems (Red Hat Enterprise Linux, Windows, and Ubuntu Linux) over the past year. For HP Itanium owners, this means that Integrity Virtual Machines (IVMs) running Red Hat Linux or Microsoft Windows Server will no longer have support from HP (since the operating system designer has ceased support).
The only bright spot for HP’s IVM is OpenVMS 8.4, which is supported under an IVM for the first time. However, response to OpenVMS 8.4 has been mixed.
Martin Hingley has an interesting article about how the dropping of RHEL and Windows Server from Itanium will not affect HP; I disagree. For HP’s virtual infrastructure – based on the IVM product – the two biggest environments besides HP-UX are no longer available. An interesting survey would be to find out how many IVMs are being used and what operating systems they are running now and in the future.
With the loss of Red Hat and Microsoft – and now Canonical’s Ubuntu – this provides just that many fewer options for IVMs – and thus, fewer reasons to use an HP IVM. OpenVMS could pick up the slack, as many shops may be looking for a way to take OpenVMS off the bare metal, letting the hardware be used for other things.
If HP IVMs are used less and less, this could affect the Superdome line as well, as running Linux has always been a selling point for this product. As mentioned before, this may be offset by OpenVMS installations.
This also means that Novell’s SUSE Linux Enterprise Server becomes the only supported mainstream Linux environment on Itanium – on the Itanium 9100 processor at least.
From the other side, HP’s support for Linux seems to be waning: this statement can be found in the fine print on their Linux on Integrity page:
HP is not planning to certify or support any Linux distribution on the new Integrity servers based on the Intel Itanium processor 9300 series.
Even if HP doesn’t feel the effect of these defections, the HP’s IVM product family (and Superdome) probably will.
