Does iSCSI need special switch?
iSCSI switches are not even required. When using iSCSI storage, an iSCSI initiator can perform some of the same basic functions a switch could be used for. An iSCSI initiator is typically free, and connects external iSCSI-based storage to host computers with an Ethernet network adapter.
How do I configure a Cisco SAN switch?
Steps
- Clear the existing zones and zoneset if present.
- Obtain the switch worldwide name (WWN): show wwn switch.
- Configure the basic zone settings:
- Create storage zones and add the storage ports to it.
- Create an FCVI zone set and add the FCVI ports to it:
- Verify the zoning: show zone.
What is SAN Switch Cisco?
A storage area network (SAN) switch is a device that connects servers and shared pools of storage devices and is dedicated to moving storage traffic. SAN switches make it possible to build vast high-speed storage networks that interconnect thousands of servers accessing petabyte-scale data.
Does Switch 2960 support IPv6?
Dual IPv4 and IPv6 Protocol Stacks The dual IPv4 and IPv6 templates on Catalyst 2960 switches allow the switch to be used in dual stack environments. IPv6 packets are not supported. In dual IPv4 and IPv6 environments, the switch applies IPv4 QoS and ACLs in hardware. IPv6 QoS and ACLs are not supported.
Should iSCSI be on its own VLAN?
So rule No. 1 in planning your iSCSI SAN is to place iSCSI traffic on its own VLAN and preferably on a completely separate, gigabit-speed network.
How do I change the VSAN on a Cisco switch?
Steps
- Issue the following command to enter configuration mode if you have not done so already: config t.
- Issue the following command to edit the VSAN database: vsan database.
- Set the VSAN ID using the following command: vsan vsan-ID.
- Set the VSAN name using the following command: vsan vsan-ID name vsan_name.
What is the difference between Fcalias and device alias?
Once a device alias is created, it applies to that WWPN regardless of VSAN. This means that you only have to define a single device alias for any given WWPN, whereas with the fcalias command a different alias needed to be defined for each VSAN.
What is difference LAN and SAN?
LAN, also called local area network, is a computer network that interconnects computers within a limited area such as residence, school, computer laboratory or office building. SAN, or storage area network, is a computer network which provides access to consolidated and block level data storage.
How do I assign IPv6 to a switch?
Enter Interface Configuration mode for VLAN 1, and enable IPv6. Assign IPv6 address for the interface. The default prefix type is set as unicast. You can configure the prefix type as anycast, eui64, or link-local address by defining the prefix type in the command.
Is the Cisco fabric switch compatible with iSCSI?
Note The iSCSI feature is not supported on the Cisco Fabric Switch for HP c-Class Bladesystem and Cisco Fabric Switch for IBM BladeCenter.
What does iSCSI mean in Cisco MDS 9000?
The iSCSI feature consists of routing iSCSI requests and responses between iSCSI hosts in an IP network and Fibre Channel storage devices in the Fibre Channel SAN that are accessible from any Fibre Channel interface of the Cisco MDS 9000 Family switch (see Figure 42-1 ).
How is iSCSI identified based on the IP address of the host?
An iSCSI initiator is identified based on the IP address of the iSCSI host. This mode is useful if an iSCSI host has multiple IP addresses and you want to provide different service-based on the IP address used by the host. It is also easier to get the IP address of a host compared to getting the iSCSI node name.
Is the Cisco MDS 9000 a Fibre Channel switch?
Cisco MDS 9000 Family IP storage (IPS) services extend the reach of Fibre Channel SANs by using open-standard, IP-based technology. The switch allows IP hosts to access Fibre Channel storage using the iSCSI protocol. Note The iSCSI feature is specific to the IPS module and is available in Cisco MDS 9200 Switches or Cisco MDS 9500 Directors.
