Managing HPE Ezmeral Data Fabric POSIX Clients

Provides a brief synopsis of HPE Ezmeral Data Fabric POSIX clients.

The HPE Ezmeral Data Fabric POSIX clients allow app servers, web servers, and other client nodes and apps to read and write data directly and securely to a HPE Ezmeral Data Fabric cluster. The following topics describe the steps for configuring and managing loopback NFS POSIX and FUSE-based POSIX clients.

Apart from the clients that are EOL, all others are supported. However, newer clients might have features that may not be supported in older clients.

Difference between the POSIX loopback NFS client and the FUSE-based POSIX Basic and Platinum clients

The following table summarizes the differences between the POSIX loopback NFS client and the FUSE-based POSIX Basic and Platinum clients:

HPE Ezmeral Data Fabric POSIX Loopback NFS Client HPE Ezmeral Data Fabric FUSE-based POSIX Basic/Platinum Client
Throughput
  • 500MB/s for remote read/write
  • 1G/s for local read/write
Greater than 2G/s for remote and local read/write
Client OS Supported Linux and Ubuntu distributions only.
Installs On Node Type
  • Client node
  • Cluster node
Access to Cluster Must have direct network access to all HPE Ezmeral Data Fabric cluster nodes. Must have direct network access to all HPE Ezmeral Data Fabric cluster nodes. However, each client only supports up to 16 clusters.
Connection to File System
  • Proxied on host to regular HPE Ezmeral Data Fabric client traffic
  • Direct, no NFS for the HPE Ezmeral Data Fabric gateway
  • No single point of failure
Security Fully secured.
Caching Buffered writes are cached in the kernel. Buffered writes are cached (only in kernel >= 3.15) if writeback option is enabled.
