Re: Processor Upgrade

Hello,

I have 2 CPUs (500 MHz) in each of the COMPAQ Alpha Server ES40.

Request you to kindly guide me on the following:
1. What is the maximum speed of the processor I can upgrade to and what is the performance gain if I do so?
2. Will there be a license issue for the customer?

Thanks & Regards,
Trupti.

Re: Re: Processor Upgrade

what exact model of the ES40?

1 - 4 Alpha 21264 Processors

6/500-MHz CPU with 4-MB L2 Late Write Cache
67/667-MHz CPU with 8-MB L2 Dual Data Rate Cache
68/833-MHz CPU with 8-MB L2 Dual Data Rate Cache

License is an issue if adding additional cpu's

Ralf,

It's EV6 (21264)-500 MHz.

Re: Re: Processor Upgrade

As far as I know, mixed-speed CPU configutations are not supported.

I would think of moving all 4 CPUs in one system, and purchasing 666 MHz CPUs into second.

CPU consists of 2 parts: Chip + License.
As far as I observed, Licence does not relates to namely THIS chip. (i.e. it doesn't have chip's serial number in it)
The fire follows shedule...

Re: Re: Processor Upgrade

Hello,

Thanks for your inputs. But please reply to foll.

1. for the existing 4 CPUs (each of 500 MHz), if I replace all 4 CPUs with 833 MHz (That's the maximum for COMPAQ Alpha ES40, correct me if I am wrong?), what is the performance gain? Is there any site/link available which shows this?

2. License will be an issue if I say replace 4 CPUs with 8 CPUs (of the same size and type, correct me if I am wrong).

Thanks in advance.

Trupti.

Re: Re: Processor Upgrade

use google to and look for: "benchmark +alpha" and you will get enough sites containing informations. It depends on your application so check for the benchmark which is near your business.

if you change the EV level or number of CPU's you'll need additional mod_units within your license.
