And this has been maintained / retained in my opinion. <BR/><BR/>And the rest of the industry has a tough time trying to get anywhere that level of availability and as best as I can tell, without extensive awareness built right into the application, the other platforms really don't offer much help.<BR/><BR/>Now recently, HP added NSAA that pushed availability way past what the rest of the industry is even looking at - and took us to seven nines. This is just way out there for those corporations looking for something I candidly term "Permanent Availability" as recovery is so fast, can you even know you took an outage?<BR/><BR/>So, NSAA is a special case, while the rest of the NonStop product line does a terrific job of providing five nines and, as I recently found out from HP NED Product Management, continues to make significant investments in giving us five nines as they pursue less expensive platform options.<BR/><BR/>Make sense?<BR/><BR/>Again thanks ....Richard Bucklehttps://www.blogger.com/profile/17723428627971060930noreply@blogger.comtag:blogger.com,1999:blog-4285729513030543746.post-66592376923249941822008-07-18T09:20:00.000-07:002008-07-18T09:20:00.000-07:00I believe the first post has a valid point - the N...I believe the first post has a valid point - the NSVA servers do not provide the same level of hardware availability as the NSAA DMR (not to mention TMR). "Loose lock-stepping" HP introduced in NSAA significantly increased hardware availability - failure of one cpu chip does not bring a logical processor down while on the NSVA servers it does. Doesn't HP admit it by continuing with the NSAA series?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4285729513030543746.post-46169031397021073772008-07-10T11:41:00.000-07:002008-07-10T11:41:00.000-07:00Neoview "complexes" are not taking on OLTP - they ...Neoview "complexes" are not taking on OLTP - they are the data warehouse within HP. Other HP systems operating independently support transaction processing - as much as I would like to see that too on NonStop!<BR/><BR/>The connection between Neoview and traditional NonStop remaines the NonStop operating system itself. It was Winston Prather that highlighted Neoview as being another NonStop "application" and I agree. And a really big application at that!<BR/><BR/>There is only one operating system development team supporting the traditional NonStop user as well as the Neoview user - and this has to be good news for all NonStop users.<BR/><BR/>Make sense?Richard Bucklehttps://www.blogger.com/profile/17723428627971060930noreply@blogger.comtag:blogger.com,1999:blog-4285729513030543746.post-72926161136054576162008-07-10T08:52:00.000-07:002008-07-10T08:52:00.000-07:00I'm curious about something - what is the role of ...I'm curious about something - what is the role of the traditional Nonstop servers within HP?

One question I am looking for clarity on is how exactly HP is positioning the new (well, not so new now) NSVA and NSAA servers against the availability offered by the previous S- and K-series servers. There's been talk of the NSVA servers not providing the same levels of hardware fault tolerance as the previous S-series servers, whilst on the other hand NSAA (particularly with TMR) provides a greatly increased level of hardware fault tolerance. And how do the new blades servers factor into this discussion? Are you able to comment on that?Anonymousnoreply@blogger.com
