Suppose if we are running 100 objects for one delphix engine and total storage at delphix engine used around 5TB, so how many CPU will be sufficient for this on Delphix engine

Nikhil,

From the perspective of any storage sub-system, whether SAN, NAS, or JBOD, neither the number of "objects" stored nor the volume of storage has any impact on the processing or activity of the storage sub-system.  For example, the storage sub-system could be completely powered down, using zero resources, and the number of "objects" stored or the volume of storage would not change.  So number of data objects or data volume is not a useful metric for determining how many CPUs to allocate to a Delphix engine.

What matters is I/O (input/output), the volume of data actively being transferred into and out from the storage sub-system (a.k.a. reads and writes).  Metrics for I/O are measured either by counting them (i.e. IOPS a.k.a. I/O's per second) or by their data volume rate (i.e. MB/s, GB/s, etc).

So if you have a database, you can measure either IOPS or MB/s by monitoring statistics within the database.  Which database software are you using?  Oracle?  SQL Server?  DB2?

Hope this helps...

Thanks Tim, so is there any case study of delphix configuration on bases of IOPS

Nikhil,

In the online Delphix documentation pages at "http://docs.delphix.com/"; the section entitled Delphix Engine System Administration has a sub-section entitled Performance Tuning, Configuration, and Analytics which include the following case-studies...

• Performance Analytics Case Study:  using a single statistic
• Performance Analytics Case Study:  using multiple statistics

For sizing your Delphix engine, there is a process using metrics such as IOPS and MB/s as input to estimate minimum requirements.

If you are not yet a Delphix customer, then someone from the Solutions Engineering team within pre-sales will be able to use this process and work with you on a sizing estimate.

Please let me know what you think?

Thanks!
