ECC/Performance Manager vs SMC/SPA

Hi Folks,

we're semi-new to Symmetrix /VMAX management (we have used SYMCLI for years, but on a limited basis) and are trying to evaluate the use of ECC and Performance manager to look at our VMAX arrays, versus using SMC and SPA for performance. Our big issue is getting enough servers to run everything, as it seems that collection of performance information cannot be done with both products on a single server.

Overall, if we chose one or another to manage our VMAX, what would be lose by only having use of one of the products?

thanks in advance!

Re: ECC/Performance Manager vs SMC/SPA

not sure who told you that you can't do that. I have one server that runs ECC 6.1 U8, Performance Manager, SMC and SPA. The question is do you need ECC ? It's a very "fat" and sophisticated product that can do so much more then just manage your Vmax.

Re: ECC/Performance Manager vs SMC/SPA

HI,

SPA alone requires 4 GB of available physical memory. If you have plans to run ECC, SPA and SMC on the same server, make sure that you have enough RAM and compute to accomadate all. If your motto is just have a software for managing and monitoring Symmetrix then SPA and SMC are good.

Thanks,

Saurabh

Re: ECC/Performance Manager vs SMC/SPA

actually SPA requires 8G now.

Re: ECC/Performance Manager vs SMC/SPA

Looking at the requirements, it appears the server we were planning to run everything on would not be able to handle it all (don't have enough memory, etc.) What we are looking at now is buying a server with enough CPU and memory to run as an ESX server with local storage, and run the various products (not ECC at first, but SCM/SPA and ESRS/Policy manager) in VM's so we can  have some flexability with upgrades or testing using another ESX server.

Do we have to worry much about storage space needed growing much over a few years, or will it top out after a while, and/or can we archive older performance data elsewhere?

Re: ECC/Performance Manager vs SMC/SPA

Dynamox, which version requires 8 GB? If you break the total requirement of SPA, 1 GB is required by MySQL process and 1 Gb is for SPA service and rest 2 GB is for other things (I assume its for OS and other imp processes).

2.1 (includes OS requirements in the 8G)  ..actually SMC and SPA are "one" product now, one installer. You still need to get license separately for each application.

Re: ECC/Performance Manager vs SMC/SPA

I've been running SPA for about 7-8 months now, collecting stats for 2 Vmax, 1 DMX3 and 1 DMX4. Right now mysql db size is around 30GB.  Now if you use performance manager and ECC, disk requirements will depend on WLA (workload analyzer) retention/collection policies. So same number of arrays with default retention/collection policies, in 1 year i have about 40G worth of performance data.

For ESRS ..were you planning on putting your gateway VMs on different ESX servers ? You should otherwise you have a single point of failure and i can tell you from experience when your site drops offline in ESRS ..you start getting a lot of calls from EMC because they think your systems all went away .

Yes, and not on storage backed by the array that it is the gateway to! We previously had it on VM's that were backed by storage from another array vendor, but as we are migrating everything to the VMAXen, we will need to have some way to ensure that EMC can still access the array if we are having issues.

We could consider having the gateway at another site in our metro area network, but would not want to worry in case of a disaster, or during a test where we cut the links (although I guess we could reroute the ESRS traffic to the local array prior to the test).

yep,  my gateways are running on local storage as well. I actually got some older DL 360 G4 and running ESXi (the free version).  I have two sites as well (metro), one site has Policy manager and two VM gateways, second site has just the two gateways that report to Policy Manager at the other site. I am ok with Policy Manager going away because my gateways cache authentication info so EMC could still get in (my policy is set to to auto-allow EMC to connect). I do backup Policy Manager to the other site so if i had a true disaster i can rebuild Policy manager relatively fast and restore from backups. I just did not want to dedicate another VM for Policy manager.
