Just wanted to know where I can find host name os details in SAS VA.

You haven't provided any context to your questions so its hard to give you the answers you want.

Are you starting a SAS VA install? If so you should be going or have gone through a design process which defines all of the hardware and software configuation in your install. That means deciding on the OS (looks like linux in your case) and if you are going distributed (multiple App servers) or non-distributed (one App server). Then you decide if you want to run the SAS metadata, mid-tier, and app servers on separate physical servers or not. There is no right or wrong here just different options.

Hello @japsas100, jap,

I think you missed an important detail on the document provided by @anja:

Under "Pre-Installation: Setting Up Users,Groups, and Ports" and the sub-paragraph "Controlling User Access to Hosts" you get all the information you need regarding the hosts. Basically, you will need the "SAS High-Performance Analytics Infrastructure 3.5: Installation and Configuration Guide" which can be found at http://support.sas.com/documentation/onlinedoc/hp-analytics-infrastructure/index.html

For correct sizing of the nodes, if you had not got an official sizing by SAS, I would definetely contact the SAS Enterprise Excellent Center.

Edited: removed the comment regarding sizing. 16 RAM per core seems quite good enough for starters

I don;t think that kind of information is share-able, since it would include sensible information.

If you want, you can always try to speak with SAS Technical Support or your SAS Account Manager.

I think you will be best served by contacting Technical Support so they can give you detailed information and help: http://support.sas.com/en/technical-support.html#contact-technical-support

Best of luck to you,

The doc provides you with pre-install steps, "in between" steps and a "what is next".

If this is not what you are looking for, and no one else might have any input or any write up on a precise

step by step install, I'd recommend that you contact Tech Sup. They might have some more precise documentation.

One thing I'd like to say tho:

Installing VA is a pretty sensitive matter, as not only the hardware has to fit precisely, but the install and config

has to be done correct as well, even more so if it is a distributed install.

I am stressing this so much (assuming that SAS Professionl Services is not involved?) because I worked with

customers who did a VA install on their own, which - espacially in a distributed environment - did not go over

very well, cost more money and more headache afterwards, users couldn't start working with it.

There are many components, such as LASR, that have to be configured very carefully so

you can use the full capability of VA.

As a best practice, working with SAS Professional Services or Education is a good way to address a VA install.

Another option is to contact your SAS Account Executive to talk about options.

As mentioned earlier, Tech Sup might be the best first step. They will not walk you through an install, but might

have some documents or papers they can point you too.

Hope this helps.

Best

Anja
