Virtual Standby to ESXI are slow

network.systex
over 6 years ago

Appliance: DL4300

Software Version: RapidRecovery 6.1.2.115

ESXI Version: 6.0

ESXI Server Spec: Dell R730x, 24 15k SAS Drives in RAID 6 - Adaptive Read Ahead - Write Back, 64GB RAM, Dual Intel(R) Xeon(R) CPU E5-2630 v3 @ 2.40GHz

Problem: Exports from RR to ESXI run below 10MB/s on a 10Gb/s network. Many of our standby's are in the TB per day range, meaning most take approx 20-30 hours to complete. During this time backups of that agent do not take place, leaving the server vulnerable.

 

Troubleshooting taken with Support:

 - All software and hardware updates completed

 - Direct 10Gb/s fibre between Core and ESXI

 - Pausing all other tasks on the Core and restarting the server

 - Change RAID policy to Adaptive Read Ahead and Write Back

 

Performing an export of an agentless backup last night seemed to run in the 100MB/s+ range, however after checking the logs this morning it dropped back down to 18MB/s after an hour.

 

Any help is appreciated, and even a comment to say you are experiencing the same and info about your setup will assist.

    That is the exact fix that I have just applied which has resulted in the dramatic increase in our speeds. Our RAM (64GB) was also filling to max when exporting, I won't know until tomorrow how this fix has affected the entire process. We track the server stats with solarwinds so I should have a good idea of how it went.
