Wilson, the HP XP product manager quoted above. I am not the JRW who has made the other informative and informed comments. That is someone else. When I comment here, I will use my full name and position at HP. Just a couple of points, while I am here. NonStop is still a very significant business for HP. NonStop does indeed manage a huge share of the ATM market, or cash points, as they are called in some countries. XP support for NonStop is unique to XP. MetroCluster support is one reason why Hitachi does sell the XP version of the array in Japan. Hitachi is a very significant reseller of HP equipment in Japan. Using the XP version lets them sell a complete HP integrated disaster recovery solution as an official HP reseller. Thanks for the interest in XP Disk Arrays. James R.

USP to 9990 replication works like charm, no limitations.

It's the same issue with USP to 9990 replication. The only diff is HP will still be in business next year, I cant say the same for Sun. USP to XP replication is all a sales thing.

Correct.

Hitachi Storage Cluster/SplitSecond are professional service engagments. While HP's Cluster Extensions is a product that continues to be refined it is ahead of HSC. MetroCluster support is different matter from CLX, it would work very well on USP-V if HP wanted to support it, but that's for people to ask HP. Certainly Non-Stop is a fairly stable market ;-) (I'm told it still runs most the cash points etc..) Costs are a bit like cross vendor replication.  I've heard both say they have a cost advantage, and a cost disadvantage, depending who is speaking. I suspect neither has the edge here, and as on replication a definitive answer is elusive. Interesting what you say on V-Max. My take is that it is still using the cache bus that general I/Os are using, so the more clever things you try to do with metadata the less bandwidth is available for data. Cheers - JRW Hi IvanE,

Oh? Rebranded SNM and SNM CLI you mean?

It’s not anymore. It same physical memory but the area is dedicated for metadata, can’t be mixed with data cache. 80 gigs in fully configured V-max
