Hardware capacity for indexing and searching

[pramodkumar]

Hi Team,

Can someone help me on hardware capacity planning if we had to implement in real-time.
On daily basis i may be getting around 4 gb data and at 24th hour getting huge data. From performance point also i want to know more.. please help me

Your requirements are less then what Splunk used as their reference server, so starting with their reference server would be a good start. 4-10GB/day is less then what many customers generate.

Your best bet is to purchase hardware which has around the same amount of CPU and memory as the server here, and then focus on getting the fastest disks possible (high RPM, high IOPS) which can meet your storage requirements (How many months do you want to retain the data?). Storage IOPS really, really matter.

A good place to start is here:
