Ceph performance is very bad with Dell R730 Power edge servers

Hi Team,

We like to evaluate the storage solution with the help of Ceph.

As this is the initial phase, we tried out direct REDHAT Ceph with ISCSI GATEWAY. The intention is to use the CEPH storage in different virtual environments(like VMware, Hyper-V) with ISCSI protocol.

Hardware Configuration.

DELL power Edge servers --- 3 storage servers

Hardware : Dell PowerEdge R730xd CPU : 2 * Intel(R) Xeon(R) CPU E5-2690 v4 @ 2.60GHz

Memory : 128Gb

RAID controller : Internal - PERC H730( We used this RAID card as a non-RAID mode for OSD disks(HBA)

Embedded NIC : 2 x 10GbE ----> For Mgmt

NIC on PCIe : Mellanox ConnectX - 2 * 40GbE ---> For Cluster replication

DISKD USED : OS Disk : 2 * 220Gb in RAID-1

OSD Disks --> 2 * 960Gb Micron-5300 SSD's /server

===================================================

Configuration :

Operating System :Debian 11

Ceph Version : 16.2.6 pacific (stable)

1 Node --> Acting as Ceph monitor, Ceph iSCSI Gateway

3  DELL Nodes --> Acting as OSD nodes --> OSD disks are not configured with separate WAL/DB disk

Total of  6 OSD's.

We tried out to test with both ESXi and Hyper-V VMs,but the  performance is very very bad and like to know if there any other tunings or recommendations are required.

 

Before testing out with Petasan CEPH,we like to know what changes are really required to take it forward.As we are targetting this CEPH storage for prod environments,we like to know where is the problem.

It seems all the above hardware are compatible and using enterprise SSD disks only.

 

Thanks,

Manivel RR

 

Can comment on direct Redhat Ceph, but it is fairly quick to setup PetaSAN and try things out.

Hi Admin,

The given hardware specs are good to test it out with petasan?

the system can work on a wide range of hardware, you can start with existing config and run some benchmarks from ui and extend if needed,

ok thanks.
