Well...nice tool...maybe...the links are dead. No power advisor download....

Another why isn't a Linux or Mac version available?

In this day and economic conditions I'd expect HP would be keenly interested in getting as much market share as possible. Removing Linux and Mac from the equation doesn't make much sense.

There are large HP customers that issue Linux and Mac to their employees.

Anyone know what the power numbers are for an MSA70 with dual power supplies and no drives?

Why do you call this server skinless?

Why doesn't HP support ESX vSPhere on these SL servers?

Hi all,

as Joe Havlik has noticed, it is not possible to configure a DC power supply for DL servers.

I have tried to use this tool in order to estimate the power comsumption for a DL360 G6 server using a DC power supply, but it is not supported.

Will DC power supplies be supported for next version?

Hi,

as Joe Havlik has noticed the Power Advisor tool does not support DC power for DL servers.

I have tried to estimate the power comsumption for a DL360 G6 server using a DC power supply but it is not supported by the current version.

Thanks!

A windoze power advisor might be useless to many of your server customers (it certainly does me no good). Will you please provide us with the Tables and Formula so we can perform the intended calculations ourselves?

Thanks

Michael

HI,

I have recently downloaded the power advisor app but I am having some difficulties in that I am able to save individual server configs but I am unable to load them back up onto either the server or rack tabs? they just remain empty? any ideas i'm running it on XP?

cheers

When will the Power Advisor have the DC version of the DL 380 G6 in it?

Hi.

We're using v1.23 and we have a problem with DL785 G6 - there's no way to choose any CPU. List of CPUs is empty. May be the reason is an empty component list for CPUs in the xml-file for this server.

re: Will 6Gb/s SAS make a difference for you?

The 6Gb/s SAS version of the P800 will launch in early 2010.

I'm trying to find 6Gb SAS controllers on the HP web server, ala a P800 like device that can go 6Gb vs. the 3Gb of the P800, is there one? Also, I see some of the raw drive capacities (300, 450, 600GB / 15k) that have 6Gb interface variants, but are all the rest of the pieces available yet to make a complete PCI-E bus to disk connection?

thank you,

Dave

"Available" means "Accessable when required". In most cases, this does not need to be 24*365.25 (or as close to that number as possible): For a teenager that wants to chat with friends, the laptop with internet access should be at hand, but may be switched off otherwise. But it's very different where Bad Things Happen if any component fails. be it hardware (network, computer, storage) or software (OS, application) or data.

From a user perspective, In either case the number of nines should be as high as possible - for the time of the requirement.

It seems - once again - that BCS-marketing still has to do some homework on the history of

Where you require system availability measured in multiple years, nothing beats OpenVMS clusters: there are several that measure uptime over 10 years, not a single second that the system wasn't available for the users, even when moving hardware around, or updating hardware and software; BUILT IN for over 30 years.

The same may be said of NonStop but I have no fugures on that. But the state of that OS is impressive as well.

Both systems are now owned by HP - but marketing does a bad job (for both HP and their customers) forgetting these systems.

The most forgotten aspect of the five 9's is the quality of (application) code running the five 9's applications.

Having all this "infrastructure" availability is not much use if the code contains flaws, behaves unpredictably or whatever. See the fact that the likes of Google, Twitter, Facebook etc. have been off the network for minutes and hours, but nobody was seriously affected. Well, those that were using Google applications were, I suppose.

Whilst the platform is of relevance, as is the infrastructure, it is of no use if the (application) code breaks.

So, the question is: when is a bug a "nuisance" and when is it not?

One definition might be that when human lives are at stake, then bugs are not simply a nuisance.

What has any of the above go to do with five 9's? If it is not obvious by now, then...we do not need them.
