Tivoli SANergy
Note: The NAS Gateway 300 is enabled for SANergy use. Although the SANergy
component is included in the product, you will need to obtain additional
licenses from Tivoli to use the SANergy client with this appliance.
Tivoli SANergy allows you to deliver shared data access at the speed of a SAN,
using Fibre Channel, SCSI, or SSA. It gives multiple computers the power to
dynamically share file and data access on SAN-based storage, using standard
networks and file systems.
SANergy combines LAN-based file sharing with the very high data transfer speeds
of the Fibre Channel, SCSI, and SSA storage networks. The result is high-speed,
heterogeneous data sharing without the performance-limiting bottlenecks of file
servers and traditional networking protocols.
SANergy extends standard file systems and network services provided by the
operating systems that it supports. As an operating system extension built on
standard systems interfaces, SANergy fully supports the user interface,
management, access control, and security features native to the host platforms.
Therefore, it provides you with all the file system management, access control, and
security you expect in your network.
With SANergy, applications that you have configured into your network can access
any file at any time, and multiple systems can transparently share common data.
SANergy ensures maximum compatibility with existing and future operating
systems, applications, and management utilities.
In addition to the SAN, SANergy also uses a standard LAN for all the metadata
associated with file transfers. Because SANergy is based on standard file systems,
if your SAN fails, you can continue to access your data through the LAN.
With SANergy, you can reduce or even eliminate the expense of redundant storage
and the overhead of data synchronization in multi-host environments. These
environments include large-scale Web, video, or file servers. Because each system
has direct access to the SAN-based storage, SANergy can eliminate your file server
as a single point of failure for mission-critical enterprise applications, reducing costly
downtime. Also, with SANergy, you can readily manage all your data backup traffic
over the storage network, while users have unimpeded LAN access to your existing
file servers.
To set up SANergy on your network, use the following steps:
1. Make sure your network is correctly configured for LAN and SAN.
2. Configure your storage system, including disk formatting, partitioning, and
volume configuration.
3. Enable SANergy bus management and device assignments. The Meta Data
Controller will then be enabled for the appliance operating system.
4. Install additional SANergy licenses on properly configured hardware clients.
