SANavigator puts SANs in perspective
SANavigator boasts full functionality, broad product support
As SANs grow over time, with switches and servers added haphazardly to the array, they can become quite difficult to track and manage. McData’s SANavigator 3.5.1 brings order to complexity and enables the SAN administrator to monitor and manage large numbers of devices.
Similar to OpenView in the LAN space, SANavigator provides an overall look at the SAN. Features include drill-down views of individual devices, asset-management functions, report creation, e-mail alert capabilities, and script responses to failures or overloads.
With its nicely evolved interface, loads of supported hardware from other vendors, functionality alerts, and reporting and scripting tools, SANavigator demonstrates a great deal of maturity compared to products such as EMC’s Control Center, Veritas’ SANPoint, and QLogic’s SANsurfer. The autodiscover and policy engine tools will be welcome additions for many administrators with large, complex, multivendor SANs.
On the downside, integrating the management tools for HBAs (host bus adapters), switches, storage, tape devices, and backup software takes some effort. However, the end result is a single, integrated platform that can manage and monitor all aspects of the SAN.
SANavigator consists of a server that performs data collection and other functions such as running scripts and monitoring SAN and device performance. One or more clients can view the data and provide a user interface to the server.
For our test, we logged in to a server in McData's lab, which provided an interesting and complex SAN to view, monitor, and manage. Remote access can be controlled by user name and password and restricted by TCP/IP address as well. The client software logs into the local server via a secure channel instead of a Web browser.
Autodiscovery is one of the most powerful tools available in SANavigator. In-band discovery polls all the devices on the SAN and reports as much information as the driver supports, including LUN (logical unit number), capacity, port number, and so forth. Out-of-band discovery can be performed by IP address or by IP subnet, making it easier to search for IP-enabled devices.
Within seconds after the autodiscovery process, SANavigator generates a visual map of your SAN. Once the device information has been accumulated, it can be exported to MySQL and IBM DB2 database formats for asset management functions.
Put your SAN on the map
The map of the SAN shows the status of all the devices on the network. Administrators can use the map to manage the SAN; plan additions; set alerts on errors, breakdowns, or throughput exceeding preset limits; and create regular reports and logs.
Reports, which can be generated in HTML format, include asset information such as serial numbers or port counts, as well as status information such as average traffic through a device.
Hovering over a given device on the map displays some of the details on the device, whereas right-clicking gives access to full information, management utilities, and more. The topology of the maps can be changed to show the map in several different layouts, including vertical, horizontal, and one that shows the logical topology with the units with the most connections at the center, and the least connected further out.
