Ceph을 소규모 클러스터 및 개발 클러스터로 사용하기위한 최소 사양에 대하여 알아보도록 하겠습니다. 다음은 하드웨어 최소 사양이므로 성능에 대해 고려하지 않았습니다. 각각의 용도에 따라 하드웨어 요구사항이 나뉘게 되며 다음을 참고하기 최소로 구성할 때 참고하시기 바랍니다.
IBM Ceph Storage 5, 6, 7 / Community 16.2.x, 17.2.x, 18.2.x 모두 동일한 최소 사양을 가이드하고 있습니다.
MON (ceph-mon-container)
- processor : 1 x AMD64 or Intel 64 CPU CORE per mon-container
- RAM : 3 GB per mon-container
- Disk space : 10 GB per mon-container, 50 GB Recommended
- Monitor Disk : Optionally, 1 x SSD disk for Monitor rocksdb data
- Network : 2 x 1GB Ethernet NICs, 10 GB Recommended
MGR (ceph-mgr-container)
- processor : 1 x AMD64 or Intel 64 CPU CORE per mgr-container
- RAM : 3 GB per mgr-container
- Network : 2 x 1GB Ethernet NICs, 10 GB Recommended
OSD (ceph-osd-container)
- processor : 1 x AMD64 or Intel 64 CPU CORE per OSD container
- RAM : Minimum of 5 GB of RAM per OSD container
- OS Disk : 1 x OS disk per host
- OSD Storage : 1 x storage drive per OSD container. Cannot be shared with OS Disk.
- block.db : Optional, but IBM recommended, 1 x SSD or NVMe or Optane partition or lvm per daemon. Sizing is 4% of block.data for BlueStore for object, file and mixed workloads and 1% of block.data for the BlueStore for Block Device, Openstack cinder, and Openstack cinder workloads.
- block.wal : Optionally, 1 x SSD or NVMe or Optane partition or logical volume per daemon. Use a small size, for example 10GB, and only if it's faster than the block.db device.
- Network : 2 x 1GB Ethernet NICs,
RGW (ceph-radosgw-containter)
- processor : 1 x AMD64 or Intel 64 CPU CORE per radosgw-container
- RAM : 1 GB per daemon
- Disk Space : 5 GB per daemon
- Network : 1 x 1GB Ethernet NICs
MDS (ceph-mds-container)
- processor : 1x AMD64 or Intel 64 CPU CORE per mds-container
- RAM : 3 GB per mds-container. This number is highly dependent on the configurable MDS cache size. The RAM requirement is typically twice as much as the amount set in the mds_cache_memory_limit configuration setting. Note also that this is the memory for your daemon, not the overall system memory.
- Disk Space : 2 GB per mds-container, plus taking into consideration any additional space required for possible debug logging, 20GB is a good start.
- Network : 2 x 1GB Ethernet NICs, 10 GB Recommended. Notethat this is the same network as the OSD containers. If you have a 10 GB network on your OSDs you should use the same on your MDS so that the MDS is not disadvantaged when it comes to latency.
Dashboard
- processor : 4 core processor at 2.5 GHz or higher
- RAM : 8 GB RAM
- OS Disk : 50 GB hard disk drive
- Network : 1 x 1GB Ethernet NICs
