Devices per server limit

I think I remember reading about the recommended number of clients ( as in managed devices not users ) per ZCM server being 1000, not sure if I am right, though. I am looking at upping the number of devices on a single ZCM 10.3.3 server to about 1300, and I hardly expect it go beyond that, ever. I am wondering if it is safe enough to assume it would cope, or if there is some kind of a "hard" limit in ZCM ( due to the database limitations or something ).

The server would pretty much be used to manage devices only - as in device imaging / deployment / inventory ( inc. an odd post-imaging bundle ) not so much to handle user logins or app deployment. It was installed with all the default settings ( database etc. ) and currently handles 400 odd devices. I would really like to avoid having to add another server unless there is a good enough reason for that.

Re: Devices per server limit

Atrofimov,

it's not a "hard" limit, and if you upgrade to 11.1, there's a new
version of Sybase, with even higher capacity (General Support for ZCM
10.x ends at the end of February, so this is a good time to consider
upgrading)

Thank you for your reply, Shaun. It is very tempting to upgrade, especially given we have just renewed our Novell subscription and are now eligible for 11.1. What is more, I was considering going 10.3.3 to 10.3.4 instead but then AFAIK would only be able to upgrade to 11.2 later on once it is out.

However, I need to add those devices pretty much now so I would probably rather do that first and then upgrade to 11.x .. providing 10.3.3 can cope with that for the time being. Like I said once devices are added it will be a pretty static environment. I wonder if anyone could confirm a 10.3.3 server handling Ok 1000+ devices in production.

Re: Devices per server limit

The Limiting factor is the active number of simultaneous communication
sessions the server can have active.

This limit is slightly under 200, but since the Server can answer one
workstation and then respond to another before the 1st one asks again
the number of active devices to which a server can respond is actually
much higher and Novell pegged the figure at about 1000.

If you increase some of the Retry Settings in the agent, you can go well
beyond that number but the chance for delayed responses during busy
periods, Such as Morning Logon Rush, increase drastically.

ZCM 11.2 with it's support for 64-bit Java will allow for far more
concurrent communication sessions and hence more devices.

In regards to the Internal Sybase Database with ZCM 10.3.x, the largest
deployment I have seen with that is approximately 8,000 Devices
That is well over the limit and I would not recommend that to anyone but
it "operated" but was on a dedicated DB server with outstanding specs.
