GRASS VALLEY K2 SAN, Installation And Service Manual

Page: 64 / 346

• The SNMP community name is public and RW permissions are unrestricted. SNMP trap
authentication is enabled.
• Spanning Tree is enabled.
• If a 10 Gig SFP+ port on the back of the switch connects to a K2 Media Server (FSM) for media
(iSCSI) traffic, the port is in the media VLAN. If a 10 Gig SFP+ port connects to a NH10GE K2
Media Server for FTP traffic, the port is in the control/FTP VLAN.
• If enough “control” ports (non-iSCSI ports) are available on a switch or switches configured for
an online K2 SAN, the Nearline system can be connected to those control ports. It is not required
that a GigE switch be dedicated to the Nearline system.
Design considerations for Ethernet switches
Extended network and switch configurations are available upon consultation with Grass Valley.
Guidelines are as follows:
• Port count — The number of client connections, FTP/streaming connections, and other connections
determine how many ports are required. As the port count increases, you must use switches with
more ports and/or multiple switches. When multiple switches are used, the port count assigned
to each VLAN and the ports used for ISLs must be considered.
• Switch/fabric design — On large multiple switch systems, designers with sufficient knowledge
have options for the separation of iSCSI traffic. For example, you can use one switch/fabric for
media traffic, one switch/fabric for control traffic, and one switch/fabric for FTP traffic.
• You can trunk up to ten Cisco ports and four HP ports together, as necessary for your switch
design.
• FTP bandwidth — This is a consideration if using multiple switches that share the FTP traffic.
In this case you must use sufficient ISLs to provide the bandwidth needed to support your FTP
traffic load between switches. FTP traffic is variable and has potentially higher bandwidth needs,
it is the primary consideration when designing ISLs. When using 1 Gig connections for ISLs,
connect and configure as follows, taking your FTP bandwidth into consideration:
Trunk/ISLs required Maximum FTP bandwidth
A trunk with three 1 Gb/s ISLs Less than 100 MB/sec
A trunk with five 1 Gb/s ISLs 100 - 300 MB/sec
A trunk with two 10 Gb/s ISLs More than 300 MB/sec
NOTE: One Gig ISLs must be an odd number (3 or 5).
If a switch's 10 Gig connections are not used for other purposes, such as connection to a K2
Media Server, you can use the 10 Gig connections for ISLs.
Configuring a switch through the K2Config application
In the K2 System Configuration (K2Config) application , features for working on a Ethernet switch
