Brief description

The BVQ SAN Package is a complete new extension package for BVQ. It introduces support for Brocade SAN switches and directors. It enables you to interactively explore your SAN configuration and check it for issues, chart SAN Switch port performance and error metrics, create reports about port utilization and drill through all the layers between SVC, BVQ, and VMware objects in end to end views.


Similar to all other available BVQ add on packages, its licensing is based on the capacity of a licensed primary system platform (Spectrum virtualize (SVC), Storwize, ...). Please review the BVQ License Information Page or ask your sales contact for more information. 

Information gathering

To collect information a BVQ SAN Scanner needs to be configured to connect to a Brocade SMI/S Provider, which can be enabled as part of a Brocade Network Advisor (BNA). There is an issue with the Brocade SMI provider and the tracking of changes, so we strongly recommend to use the free (headless) Brocade SMI provider separately or at least to switch off "Track changes" in the BNA. See Supported environments and BVQ server requirements for more details and the supported versions of the Brocade SMI provider.

Supported SAN objects

This first version of the BVQ SAN Package supports basic elements of a SAN environment. The following overview depicts the elementary relationships of these objects and their link to connected BVQ objects:

Where to find SAN objects?

Similar to all other objects, they show up in the BVQ Path browser inside the view property panel or can be opened as a Table from the Favorite browser. All SAN objects can be combined in an end to end relation to all other objects.

 BVQ SAN object details
SAN AgentThe SMI Provider gathering information for the monitored SAN Devices
SANThe SAN to which the monitored SAN Fabrics belong to. Only routed SANs will contain more than one SAN Fabric in a SAN.

SAN Fabric

Part of a SAN, that contains one or more interlinked (logical) SAN Switches.
SAN SwitchRepresents a logical SAN Switch configured inside a physical SAN Switch or Director as part of a SAN Fabric.
SAN ChassisRepresents the physical SAN Switch or Director. A BVQ Room connected to a BVQ Site can be configured for it.
SAN Switch portFiber channel Port of a SAN Switch. This can be physically cabled to a SAN Node port or to a SAN Switch port of another Switch.
SAN TrunkMultiple SAN Switch ISLs can be bundled to a SAN Trunk to improve the performance an availability of a Switch to Switch connection.
SAN ISLInterconnection between two SAN Switch ports to bind another SAN Switch into the same SAN Fabric. Multiple ISLs can be grouped to a SAN Trunk
SAN Node portFiber channel port inside a SAN attached device (host, storage system, ...) connected to a SAN Switch port. BVQ directly connects them to gathered Ports of BVQ monitored storage systems.
Primary identifier: World Wide Port Name (WWPN)
SAN Node

One or more ports physically places inside the same device show up in a SAN Node.
Primary identifier: World Wide Node Name (WWNN)

SAN PlatformA configured FDMI driver of a SAN Node device can deliver more helpful information about the system driving the SAN Node ports (e.g. Hostname, Device driver Version).

Object attributes

BVQ displays the full set of all reported attributes for each supported SAN object. Be aware that only a subset of configuration parameters is reported by the Brocade SMI provider. In addition, BVQ calculates counters for each grouping object, so that their number of grouped objects are known. For example a SAN Fabric knows how many SAN Switches it contains, how many SAN Switch ports they have and how many of them are connected or free for use. Please explore the BVQ SAN Table view favorites to get an impression of the most important attributes.

Performance and error metrics

The BVQ SAN Package gathers all SAN Switch port statistics delivered from the Brocade SMI provider. Similar to all other statistics, you can simply drill into a chart with the statistics related to an object with a simple click on the SAN entry in the context menu of this object:

That opens our well known BVQ Chart view, where you can select statistic metrics in the selection panel. The following screenshot shows the full set of available metrics in the expert tab:
