About CDP sizing documents

Post by yu_ooyama »

Hi,

My customer is thinking of using CDP.
Do you have any sizing documents for building CDP?

The documentation mentions minimum requirements, but under what conditions should the performance of the CDP Proxy be improved?

Hello,
more RAM & CPU & Bandwidth = more performance.

CPU will rarely be the bottleneck. RAM requirements are depending on the IO / storage traffic. Bandwidth requirements are proportional to your storage network requirements (well, it also depends on the RPO)

Following things are to consider
1) Throughput (average aggregated write rate of all machines during RPO time)
2) RPO (how much data are you allowed to lose)
3) "issue time" (network outages, merges, storage controller failovers etc.)

We recommend to calculate with minimum 120 seconds (2min "issue time"). For estimation, you only need 2 or 3, because one value is larger than the other.

So the main question is: how much storage throughput do you have for 2 and 3.

And how many VMs (disks) do you plan to replicate?

Best regards,
Hannes

Hi Hannes,

The configuration of the customer is as follows

Host type:VMware
Number of VMs:10
Total VM Data Volume:6TB
Network:1Gb

In this case, what level of performance is required for the CDP Proxy to meet the requirements?

Hello,
the most important information are missing: storage throughput and RPO

Minimum requirements should be fine. If not, the bottleneck needs to be fixed.

Also, keep in mind we have the deployment calculator built right into the new CDP Policy wizard. This one takes all the variables into account.

I see no reference of this calculator in the User Guide: https://helpcenter.veeam.com/docs/backu ... ml?ver=110

I would like to see some details about this.

hmm, I see it in step 10
To test whether VMware CDP proxies available in the backup infrastructure can handle replication, click Test.

Veeam Backup & Replication will analyze available CPU on all source and all target VMware CDP proxies, the maximum VM disk write speed during the last hour, and will calculate approximate requirements for VMware CDP proxies. In the CDP Infrastructure Assessment window, you will see the calculated values:

Should CDP Proxies be scaled up or out?

whatever is easier for you (usually bandwidth constraints). if the "up" limit is reached, then "out" is the only way in any case :-)
