What is a Cisco VSAN?
A VSAN is a virtual storage area network (SAN). A set of protocols run over the SAN to handle routing, naming, and zoning. You can design multiple SANs with different topologies. With the introduction of VSANs, the network administrator can build a single topology containing switches, links, and one or more VSANs.
How do I change the VSAN on a Cisco switch?
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 isolated VSAN?
The use of VSANs allows the isolation of traffic within specific portions of the network. If a problem occurs in one VSAN, that problem can be handled with a minimum of disruption to the rest of the network. VSANs can also be configured separately and independently.
What is VSAN in fabric?
You can achieve higher security and greater stability in Fibre Channel fabrics by using virtual SANs (VSANs). VSANs provide isolation among devices that are physically connected to the same fabric. With VSANs you can create multiple logical SANs over a common physical infrastructure.
What is the use of vSAN?
VMware vSAN uses a software-defined approach that creates shared storage for virtual machines. It virtualizes the local physical storage resources of ESXi hosts and turns them into pools of storage that can be divided and assigned to virtual machines and applications according to their quality-of-service requirements.
When was vSAN introduced?
August 2013
VMware Virtual SAN, or I should say VMware vSAN, has been around since August 2013. Back then it was indeed called Virtual SAN, today is it is officially known as vSAN, but that is what most people used anyway.
How do I enable ports on a Cisco SAN switch?
Steps
- View the port groups available in a Cisco switch: show port-resources module blade_number.
- License and acquire the required port in a port group by entering the following commands in sequence: config t interface port_number shut port-license acquire no shut.
- Save the configuration: copy running-config startup-config.
What is vSAN and how it works?
What is the difference between vSAN and San?
Differences Between SAN and vSAN vSAN only work with ESXi hosts, while SAN leverages storage protocols such as FCP and iSCSI. With a traditional SAN, storage administrators are required to pre-allocate storage on different systems, while vSAN automatically converts local storage resources into a single storage pool.
