Hello Fritz et al.,
As you may already know, we just received a new server dedicated to Qserv with the following configuration:
- Dell PowerEdge R730/xd with
+ CPU: 2 x Intel Xeon E5-2680 v4 (2.4 GHz, 35 MB cache)
+ RAM: 16 x 32 GB RDIMM = 512 GB
+ Persistent storage:
= 1 x Intel NVMe P3700 PCIe card, 2 TB (intended for data storage)
= 2 x SSD 1.6 TB (intended for data storage)
= 10 x hard disks 1 TB, SAS 7200 rpm, 12 Gbps (intended for data storage)
= 2 x internal hard disks 300 GB, SAS 7200 rpm, 12 Gbps (intended for system disk)
+ Network: 1 Gbps and 10 Gbps NIC
With this node, you should be able to store the entire index needed by the query distributor.
I would like to know what kind of configuration you need concerning the storage disks, in terms of RAID configuration, filesystem used and mount points. I would propose this one:
* NVM:
- Mount point: /qserv_nvm
- xfs (no RAID configuration).
* SSD:
- Mount point: /qserv_ssd
- xfs (no RAID configuration)
* "normal" hard disks:
- Mount point: /qserv
- RAID-6 in xfs (same configuration on ccqserv{100..149} if I remember correctly).
Moreover, we propose for that machine:
- Hostname: ccqserv150.in2p3.fr
- CentOS 7 with Docker 1.9.12.
- Access to GPFS in read-only mode (mount point: /sps/lsst).
- AFS
- Ganglia monitoring.
- Access to ccqserv150 (with a private IP address) from ccqservbuild.
Do you agree? Is there anything else you would like to have on this new server?
Thanks,
Yvan
