EMC VisualSAN Version 4.1 Support Matrix

VisualSAN Requirements

VisualSAN Discovery

VisualSAN uses the following methods to automatically discover

devices in the SAN.

These methods operate independently of each other, and while they

may discover the same device twice, VisualSAN reconciles these

findings and provides a single representation of each device.

SNMP — VisualSAN attempts to automatically discover most

SNMP-enabled devices (aside from CLARiiON

storage systems)

within the IP address discovery range. If the device or host is shown

as supported in this document, VisualSAN automatically renders the

device in VisualSAN and obtain property information on that device.

If the device is not supported, VisualSAN still renders that device,

but gives it an "Unknown" designation.

CLARiiON Storage Systems — CLARiiON storage systems are

discovered using a proprietary method that does not involve SNMP.

For more information about discovery of CLARiiON systems, refer to

Supported CLARiiON Storage Systems on page 20.

Switch Name Server — If VisualSAN discovers a supported switch,

VisualSAN will automatically query the switch for the devices it has

discovered and added to its name server, and correlate that

information against its own repository of SNMP discovered devices.

The Switch Name Server can provide additional connectivity

information, the manufacturer's name, and device's type.

If a device is discovered by the Switch Name Server and not via

SNMP or through CLARiiON discovery, VisualSAN will not be able

to monitor that device by providing event or status information. Also,

devices discovered in-band by the Switch Name Server that are not

explicitly supported by VisualSAN may not be rendered correctly (or

at all) in the VisualSAN management console.

HSG80 Storage Systems — HSG80 storage systems are discovered

using a proprietary method that does not involve SNMP. For more

information about discovery of HSG80 storage systems, refer to

Supported Open Storage Systems on page 24.

EVA Storage Systems — EVA storage systems are discovered

through the HPQ Appliance. After VisualSAN discovers the HPQ

Appliance, VisualSAN discovers the EVA storage systems the

appliance is managing. For more information about discovery of EVA

storage systems, refer to Supported Open Storage Systems on page 24.
