Re: Dedup on single core? (SOLVED)

@anton We were aware of the storage requirements so we put the Dedup repository on a 15k FC San. Moreover, as you can see from the graph, disk occupation is far below a single SATA disk bandwidth. @Vitalii Thanks for the reply. So we'll wait for the next major version in order to retest the Dedup ag...

Re: Dedup on single core?

I tried to add a second Dedup Virtual Drive and copying 3 files concurrently on the 2 drives.

The situation doesn't change and the overral throughput from the Client to to the iSCSI target remains of 30 Meg / Sec with a CPU % of 12 on the Starwind server

Re: Dedup on single core?

Hi, thanks for the reply, i was asking because with a Dedup virtual drive we can reach a max performance of 40 MBytes / Sec, with 80% allocated ram on the Starwind server, and just 1 core using 15% CPU. The other CPUs are 0 % used, so it's clearly using a Single core for the dedup process. I can giv...

Dedup on single core?

Hi, we are testing the Starwind iSCSI solution, with a virtual deduplicated device. We've noted that on a 8 cores machines, just 1 core is used during the deduplication process. Can someone confirm that the Dedup engine just use a single core? We are searching for a Deduplication Multicore solution ...
