CEPH Storage

CEPH Storage
Software
Ceph Version Ambedded tuned Ceph community versions
Management Interface
  • Ambedded Web-based user interface: UniVirStor(UVS) Manager
  • Command Line Interface
Automation The UniVirStor Ceph management GUI (UVS Manager) automates management functions for day-1 and day two operations, including cluster deployment, storage service provisioning, monitoring, and software updates.
Access Authentication Control
  • Policy control to limit users to access pool & block device
  • Ability to Integrate with Microsoft Active Directory, lightweight directory access protocol (LDAP), AWS Auth, and KeyStone
Multi-protocol support A storage platform supports multiple industry-standard storage protocols for block, file and object storage.
Monitoring & Notification
  • UVS, Ceph, and Grafana dashboard
  • Alert sent through email
  • SNMP
Ceph Storage Pool Base
Scale-out cluster
  • Grow the cluster to thousands of storage drives
  • No single point of failure
  • Cluster performance is linearly scalable with the number of drives (OSD).
Self-healing and
auto rebalancing
  • Balances data distribution throughout the cluster nodes
  • Handles failures without interruption, automatically recovering to the predefined data resilience
Highly available Withstand loss of multiple nodes/racks without disrupting service availability or data safety
Data protection
  • Striping, erasure coding, or replication across nodes with predefined rule
  • Configurable number of replica and erasure coding profile
  • CLAY erasure coding to reduce the data recovery time
  • Renamable bucket type: root, region, zone, data center, room, PDU, raw, rack, chassis
Disk encryption OSD disk drives can be encrypted to protect data when drives are removed
Data Compression Inline object compression with target compression ratio
Cache Tiering Use faster storage pool as cache tier
Ceph Deployment And Management
Software update
  • Automated rolling update without downtime. Data services are available during the update.
  • Updates include Linux, Ceph, and UVS manager
General
management
  • Host management: Scan and manage server nodes in the Ceph cluster
  • Deploy the NTP server or use an external NTP serv
  • Push NTP client to ceph hosts
  • Log management
  • Notification
  • User management
Ceph daemon
services
  • Cluster initialization
  • Deploy and manage MON, OSD, MDS, RGW
