Latest version of HPUX

[Arunvijai_4]

It depends on the SAN environment you have, the equipements, drivers, etc.. I would say this, 11.23 is being supported by all vendors of SAN and you see can more of it too (support).

Probably no real difference in efficiency for the SAN Shiv,

There may be higher limits on number of LUNS for a non-hp array, but I see full support for 11.11.

SAN efficiency is not reason alone to go with a higher version of HP-UX. If your applications support it, going to a higher version means one less future upgrade.

Hi ShivKumar,

The latest verion of the HP-UNIX is HPUX-11.23. This supports both windows and unix.
This support SAN environment also.

"Support for networking and storage solutions for Itanium-based systems,
including dynamic expansion of storage components and extended support for
Gigabit Ethernet and Gigabit Fibre Channel interconnects." -- According to the whitepaper published by IDC.

Krishna

Shiva,
The latest one is HP-UX 11i v2,

regards,
Krishna

FOr whats new in 11iv2 see this doc:

http://h71028.www7.hp.com/erc/downloads/hpux-11i-v2-overview-sept04-v19-050510.pdf

As CMT will only be introduced with the arrival of the Itanium2 processor code-named 'Montecito', some time next year, the support for it in 11iv2 is effectively moot.

What does CMT give you? Extra performance by allowing multiple threads of execution in a processor core - the aim being (if I understand correctly - I'm no processor expert) to reduce 'stalls' - i.e. long latency events such as cache misses etc.

This is getting of the topic, since Montecito is in the Itanium family of processors, but it a dual core processor with each processor capable of processing two threads. But while the dual core come closest to doubling performance over a single thread, the dual threads per core helps less. Basically, if the processor core is stalled and waiting on a memory fetch, then it can relatively quickly switch to processing a second thread. But there can be draw backs. While each of the processor cores has its own cache, when you run two threads on each core, they must share the cache for that core, so running two processes on a single core can have the effect of reducing the amount of cache for each process. HP-UX 11i v2 will be able work in this new environment, but 11i v3 should be better optimized for it, but only on Montecito based Itanium servers. There will be other features in 11i v3, but the feature set may not be fully defined at this time, so it would be premature for HP to talk about it.

What does it mean by the statement "HPUX-11.23 supports both Windows and Unix" ? How come one os will run another os ?

[Ted Buis]

Where are you reading that? HP-UX 11.23 supports CIFS so can be a Windows file server, but don't support Windows. Integrity servers can run either Windows, LINUX, HP-UX or OpenVMS, but that isn't what you quote.
