#BROCADE SAN SWITCH ZONING GUIDE SOFTWARE#
VSAN capabilities allow Cisco NX-OS software to logically divide a large physical fabric into separate, isolated environments to improve Fibre Channel SAN scalability, availability, manageability, and network security. Virtual SAN (VSAN) technology partitions a single physical SAN into multiple VSANs. Cisco NX-OS software also can be configured to load balance across multiple same-cost FSPF routes. Load balancing using PortChannels is performed over both Fibre Channel and FCIP links. PortChannels load balance Fibre Channel traffic using a hash of source FC-ID and destination FC-ID, and optionally the exchange ID.

In the autoconfigure mode, ISLs with compatible parameters automatically form channel groups no manual intervention is required. If a port or a switching module fails, the PortChannel continues to function properly without requiring fabric reconfiguration.Ĭisco NX-OS software uses a protocol to exchange PortChannel configuration information between adjacent switches to simplify PortChannel management, including misconfiguration detection and autocreation of PortChannels among compatible ISLs. ISL ports can reside on any switching module, and they do not need a designated master port. With this feature, up to 16 expansion ports (E-ports) or trunking E-ports (TE-ports) can be bundled into a PortChannel. PortChannels aggregate multiple physical ISLs into one logical link with higher bandwidth and port resiliency for both Fibre Channel and FICON traffic. Trunking is supported on E ports and F ports. Trunking enables interconnect ports to transmit and receive frames in more than one VSAN, over the same physical link. Trunking, also known as VSAN trunking, is a feature specific to switches in the Cisco MDS 9000 Family. This feature is available only for Cisco MDS Blade Switch Series, the Cisco MDS 9124 Multilayer Fabric Switch, and the Cisco MDS 9134 Multilayer Fabric Switch. NPIV is used by edge switches in the NPV mode to log in to multiple end devices that share a link to the core switch.

Cisco MDS 9000 family fabric switches operating in the NPV mode do not join a fabric they only pass traffic between core switch links and end devices, which eliminates the domain IDs for these switches. N port virtualizer (NPV) is a complementary feature that reduces the number of Fibre Channel domain IDs in core-edge SANs. In addition to being useful for server connections, NPIV is beneficial for connectivity between core and edge SAN switches.

HBAs that support NPIV can help improve SAN security by enabling zoning and port security to be configured independently for each virtual machine (OS partition) on a host. If you do not configure a domain ID, the local switch uses a random ID.Ĭisco NX-OS software supports industry-standard N port identifier virtualization (NPIV), which allows multiple N port fabric logins concurrently on a single physical Fibre Channel link. The domains are configured on a per-VSAN basis.

The Fibre Channel domain (fcdomain) feature performs principal switch selection, domain ID distribution, FC ID allocation, and fabric reconfiguration functions as described in the FC-SW-2 standards. When you use expansion modules up to 8 Fibre Channel ports are available on the Cisco Nexus 5010 switch and up to 16 Fibre Channel ports are available on the Cisco Nexus 5020 switch.Įach Fibre Channel port can be used as a downlink (connected to a server) or as an uplink (to the data center SAN fabric).

The SAN switching features documented in this guide are described below.įibre Channel ports are optional on the Cisco Nexus 5000 Series switch. The Cisco Nexus 5000 Series NX-OS software can configure and manage features such as VSANs, SAN device virtualization, dynamic VSANs, zones, distributed device alias services, Fibre Channel routing services and protocols, FLOGI, name server, FDMI, RSCN database, SCSI targets, FICON, and other advanced features described in this guide.
