Your speed is just a half of ssd speed. I guest just because of your HDD speed. Not full ssd. What do you mean drbd for database ? Is this system seperate from ceph ? And ceph is not the good performances for database ? I plan to test again with 10Gbps network in this month end. I will update...

Hi, In the corner of BA, people think how to get better ROI with the same cost invest. IMHO i see their storage is quite optimized with efficient cost. They are using 1 SSD for processing data and then store processed data to HDD (SATA or SAS) per node. I'm still looking for better way to...

Thanks for your sharing information and follow up. I forgot to says that we are using 2 x X5650 per nodes. I will retest when i'm back our HO. I'll contact with you via your site Odiso.com for consulting services. Thanks again, Nghia,

There are 2 cases: - local storage you can get this result - for PCS system all data replicate via network to sync data from local node to all node in cluster. But for read all VM will read on local SSD on the same node. So network in their design just use for replication, 1Gbps is enough in...

Thanks for your interesting articles. Can i use 1 Intel DC S3700 as journals for per node and multiple MX200 to store data. I havent try this yet. Sent from my iPhone using Tapatalk

Thanks for your answer. May i know queue depth meaning in this case ? Is it on network level or storage level ? For contrast, the same setup with Parallel Cloud Server (Odin) the dd test can get better at 1GB/s with 3 node above. I'm able to reach 400000 iops 4k randread / qd=32 from 1vm...

May i know how many disk is enough ? I read many articles talking more disk is better and using SAN 10Gbps for storage but i do not see any article mention clearly requirement disk for production environment. Sent from my iPhone using Tapatalk

Hi, Anybody try Proxmox + Ceph storage ? We tried 3 nodes: - Dell R610 - Raid H310 support jbod for hot swap SSD - 3 SSD MX200 500GB (1 mon + 2 osd per node) - Gigabit for wan and dedicated Gigabit for Ceph replication When i test dd speed on 1 VM store on Ceph i only get avg speed at...

Hi all, For openvz we can check what VPS using IP via command vzlist -a but how about VM ? We provide IP 192.168.1.1 for VM A but VM A will manual set more IP .2 and .3 and goes on... In the case we have more than 1000 VM in proxmox system so how to recognize what VM using these IP ? Thanks,

Thanks for your correction, but how do you know the IP address of KVM without login to that VM ? Proxmox do not show this information like VMWare Guest tool or Parrallel Cloud Server tool.

Hi Pirateghost, Screenshot is what i mentioned for network tab. DHCP will broadcast in your network, it's suitable for internal company but not for datacenter or hosting environment due to broadcast packet to your network. Furthermore, what happen if your client try to set manual IP address...

Hi, I'm new to ProxMox so i have some questions related to IP address after searching many days. 1. Is there any way to automatic issue IP for VM and OpenVZ ? In SolusVM KVM auto assign IP for client after 1 click add IP via web admin and VM/openvz can access internet. 2. How to detect IP of...
