I am planning to build a production 3 nodes Petasan cluster with this hardware:
HP ProLiant DL380p Gen8 Storage Server
- 2x Xeon E5-2680 8-Core 2.70 GHz
- 128 GB DDR3 RAM
- Smart Array P420i with 512 MB FBWC cache (6G SAS / 6G SATA)
- 1 x Intel X540-T2 Dual Port 10 Gbit/s RJ45 Ethernet Server Adapter (Ceph backend)
- 1 x Intel X540-T2 Dual Port 10 Gbit/s RJ45 Ethernet Server Adapter (Esxi Hosts)
- 2 x 240 entreprise SSD 6G (raid 1 petasan installation)
- 4 x 240 entreprise SSD 6G (journal)
- 18 x 1.2 TB 6G 10K SAS disks
I am looking for balanced performance to stor about 60 Esxi VMs (mostly RDS/Office usage) and i have a few questions.
I am planning to enable Raid flash acceleration to get a performance boost, 512 MB FBWC cache is enought? A 2 GB cache can make a big difference?
The 6G SAS interface can be a bottleneck vs 12G SAS, same for DDR3 vs DDR4?
Any good advises is welcome.
Thank you.
Aracno.

But let's wait for Admin's comments. 😉

July 9, 2018, 1:42 pmQuote from admin on July 9, 2018, 1:42 pmThe 512 MB cache is low, but still would make a positive impact. I would recommend you install the existing configuration as is and use the PetaSAN benchmark ui to get quantitative performance and load utilization.
You may do with 64GB ram, but if you already have 128 i'd recommend you leave them as is.
