I have one question regarding the disk space for all DX Spectrum. Do we have to follow any disk layout ?? or consider the default?

Hello,
Will those users be accessing One CLick using the Javaclient App or the WebApp ?
If they will be using the WEBApp you should go to 32Gb of memory and you may need more CPU depending how active they are and what they are doing...
If they log in and do nothing - No problem
It they have a Topology View open with 4000 devices and Live Pipes enabled, Clone Several Search Result views - have Port Performance Views open, and a 10,000 Alarm view... They will be consuming More resources.
Log into the Admin page and you will be able to see CPU / Memory and Latency data for each WebApp user.

Hi Donald Laberge,
That's good questions.
I've just confirmed that there will be 100 users. not sure.
at a time there will be 10 -15 users will be active.
I've assigned the 16 GB RAM to a One-click server. Do you think that gonna be enough ??
Thanks.

Good Afternoon Himanshu,
Eight VCPU will be more than what would be required to support a generic 1,000 Managed devices.
Four VCPU should be more than sufficient.
How many users will be accessing One Click - Will they be using the WebApp or the One Click Java client ?
Consider having 1Gb per user on the One Click servers for each WebApp instance ( user ) executing.

Good Job then!
so we all need to make sure the customer has a supported environment that will meet their needs.
If your going to make a significant investment in the software you don't what to put it on a minimal h/w solution.
Himanshu: Your solution would be more than adequate for that environment and provide you with complete redundancy.
A bit more disc space on the SRM server .

Actually I am supporting this customer and I've been doing it for the past 14 years, since I initially installed Spectrum 8.1 in their environment.
Indeed, there are many flavors of devices and differences span from 4 ports access router to 10.000 ports Core infrastructure device. For my customer's needs, I'm confident that this will be working, as it is now with 4 SS.
On the other hand, I've seen a major service providers with close to 120 Core devices and a number of 450.000 interfaces in total. I do not know of a service provider to have 10.000 core devices with 10.00+ interfaces each, to be in this case, so 4SS should not suffice.
QoS monitoring in SPECTRUM is rather useless for just alarming purposes, as PM should be used better to track historically the queues and provide alarming the relevant values. Same goes for IPSLA, since the IPSLA reporting was removed from the CABI SRM reporting.
This tells me, that this customer, with 900+ devices cannot have all Core devices (10.000+ interfaces), as these figures that are presented would not suffice for such a situation.
The hardware assessment should be done based on gathered customer information and the figures that I saw here, I think they're grater then an actual implementation requirements.
What the system is good at and should be used extensively is topology relations for root cause analysis. That and Service Manager, but I haven't seen many customers using effectively Service Manager, as they find it rather hard to configure and maintain.
CA/Broadcom has always been conservative, as I've been saying with figures of number of supported devices. What happens if you run a performance assessment on the SS 6 months in its deployment and the load ends up to be 40%? It's a good 60% reserve for future usage? I've been there several times with the CA provided figures.

Catalin: Will you be supporting this customer ?
10,000 network devices or 4,000,000 models of what types - Event Models ? Pingables ? Juniper Service provider switches with 100,000 interfaces ?
The types of devices managed and their numbers makes a huge difference in the resources required.
Himanshu: This configuration will put you in a position there you should not have any issues with your implementation.
1.Spectro server 1 ( Primary)
2.Spectro server 2 ( Secondary)
3.OneClick server
4.Spectrum report manager ( One CLick + Jasper Report Manager )
Losing any one of those systems, will not impact your ability to manage the environment.

I never install it like this, it's a waste of resources. I usually install SS and on one of those I put the one OneClick server with SRM. A secondary SS would contain also an additional OneClick server to have some sort of manual failover for the OC, as OOTB failover for OC is not available.
In one customer environment that I have, I use 4 FT SS for managing 10.000 network devices. I'm planning to consolidate this, as one SS can now handle up to 4.000.000 models, if I remember correctly from the last presentation I attended. I always host the SRM on a secondary SpectroSERVER. I usually don't get any failovers, unless there are hardware problems.
It really depends on what you want to do with it, if there are any integration that need to be configured for other 3rd party systems, if you want/plan to actively monitor QoS, IPSLA.
I would say that the OC can handle SRM also, in a scenario where you don't install any SS on that server.
When CA stated that there's a limit of 2000 devices/200.000 models per SS, I had server that had twice the amount of devices and were running fine. I've seen problems when reaching 750.000 models/SS on those systems. They do provide conservative figures.
What really matters on the SS machine is the CPU speed in Mhz. The higher, the better.

Hi Joseph,
We're planning to install the distributed CA Spectrum with the fault-tolerant
1.Spectro server 1 ( Primary)
2.Spectro server 2 ( Secondary)
3.OneClick server
4.Spectrum report manager
From my understanding now we need a four server to carry out the distributed CA Spectrum with the fault-tolerant.
Thank you joseph for clearing my doubts.

If you are going to use FT, then you will need to install 2 SS's. One will be the primary and one will be the secodnary.

Hi Joseph,
Thank you for your answer.
Definitely, we will go distributed system, in this case, we gonna need a 3 server to install the SS, OC, SRM.
If we're choosing the fault-tolerant scenario then do we need install the two SS servers or SS & OC servers.
Thanks.

You can install SS, OC and SRM on a single system but it is not generally recommended as there may be performance issues with CPU, memory disk space etc.
It is recommended to install SS, OC and SRM on separate systems.

Hi Catalin,
Thank you for your response.
Please correct me if I'm wrong. So Can we go ahead and install the SS & OC server & report manager on one server like standalone. ( FYI it would be enough to manage the 950 devices? am I right?
Thanks.

One server is more than enough. A second one would be required if Fault Tolerance is considered.
That is, if you have some regular devices, and not big 1000+ interfaces on each of those 900 devices.

Hi,
We're planning to manage the 900 devices.
I was trying to access the ca spectrum sizing tool but I'm unable to access it.
I'm not sure how many Spectro server and One-click server we need to manage the 900 devices.,
Any help will be appreciated
Thank you.

Hello,
How many SpectroSERVER and One Click servers are you planning to install ?
You might be better off to use the distributed installation process when deploying multiple systems ?
Thank you,
Don

Hi Guys,
We're planning to deploy to the DX spectrum in our network.
We do have a standalone DXn Spectrum in our lab. it was but easy to install all (Spectroserver & One-click server on one box).
Now We're planning to install the distributed DX Spectrum on our network.
I've been reading the docs but for me, it was a bit confusing.
We're going for Linux that I'm sure & I know all the servers requirements ( RAMs, Processor &, etc)
The main thing what ( Spectro server & One-click server to where to install )
Any proper documents or user guides will be helpful.
Thank you in advance.
