Single Zimbra open source edition for 1000 users

[RohitSavana]

We are planing to use zimbra open source edition for around 1000 users.Our Server's hardware specs are Intel Quad core Processor, 8 GB RAM and 1 TB SAS for storage.
Is our server hardware's capacity is enough to run zimbra server for 1000 users.

Kindly suggest good hardware specs for 1000 users for internal email server.

Sorry for doing that. But I have already searched the forum a bit and all I found was people asking whether their config is ok for deployment of certain number of users. If you can help it would be great. I just want a generic suggestion for no. of cpu cores and speed, amount of ram and storage to support 1000 users. Thank you.

Hello Jsengupta,
I think you are asking the wrong questions to the forum and to yourself.
How may concurrent access you think you need to support ? (you could have 1000 users that access their email once a week or 1000 users that use 5 devices each all days and so 5000 active sessions.
Zimbra is heavy on SQL so not how big but how fast is your storage?
When you will be able to answer those questions maybe you will have a clearer picture on your deployment.
Just my 2 cents.
