HP StorageWorks Scalable File Share - Manual (Page 19)

Figure 1-1 Logical overview of the Lustre file system
A typical Lustre file system consists of multiple Object Storage Servers that have storage attached to them.
At present, the Object Storage Servers are Linux servers, but it is anticipated that in the future the Object
Storage Servers may be storage appliances that run Lustre protocols. The Object Storage Servers are
internetworked over potentially multiple networks to Lustre client nodes, which must run a version of the Linux
operating system. Similarly, one or more MDS servers with associated storage are also interconnected with
client nodes.
HP SFS Version 2.2 supports a single MDS server only.
1.1.2 Overview of HP SFS
HP SFS is a turnkey Lustre system that is delivered and supported by HP and has the following features:
• Provides Lustre services in an integrated and managed fashion.
• Provides access to Lustre file systems by way of Lustre client-server protocols over multiple
interconnects.
• Provides a single point of management and administration for the Lustre services.
• Allows legacy clients that can use only the NFS protocol to access the Lustre file system by configuring
a Lustre client as an NFS server of the Lustre file system.
• Allows Windows® and CIFS (Common Internet File System) client systems to access Lustre file systems
via Samba.
In an HP SFS system, the administration service allows you to manage the following activities from a single
server (the administration server):
• Installing the servers
• Automatically configuring the operating systems on the servers
• Detecting and configuring storage attached to the servers
• Creating, deleting, and configuring Lustre file systems
• Providing a Lustre configuration management service that distributes Lustre file system information
using the LDAP or HTTP protocol, or within the Lustre Protocol
• Booting and shutting down the HP SFS system
• Monitoring file system and storage events
