What is SAN zoning basics?
SAN zoning is a fabric-based service for grouping the devices in a SAN into logical segments to control communications between those devices. When zoning is configured, only devices in the same zone can communicate with each other; cross-zone communication isn’t permitted.
How do you do LUN masking?
How To Perform LUN Masking in vSphere 6
- Find LUN ID.
- Find out path information of a given LUN.
- Find the Multipath Plug-in that are currently installed.
- List claimrules : esxcli storage core claimrule list.
- Select method of lun masking.
How do I install and configure SAN storage?
Configuring SAN storage
- Configure the SAN to create the LUNs to be used by queue managers, and allow access from the appliance host bus adapters.
- Define a volume for each LUN, using the LUID to identify it.
- Initialize the file system for the volume.
What is difference between WWN and Wwpn?
A WWPN (World Wide Port Name) is physically assigned to a part in a Fibre Channel device, such as a FC HBA or SAN. The WWNN (World Wide Node Name) is a World Wide Name assigned to a node in a Fibre Channel fabric. …
What are SAN protocols?
The most common SAN protocols are:
- Fibre Channel Protocol (FCP). The most widely used SAN or block protocol, deployed in 70% to 80% of the total SAN market.
- Internet Small Computer System Interface (iSCSI).
- Fibre Channel over Ethernet (FCoE).
- Non-Volatile Memory Express over Fibre Channel (FC-NVMe).
What’s the difference between soft zoning and WWN zoning?
WWN zoning is sometimes referred to as soft zoning. Port zoning groups particular switch ports together to allow any device connected to those ports to communicate with each other. The advantages and disadvantages of port zoning are the opposite of those for WWN zoning.
Is the Switch port irrelevant in WWN zoning?
The switch port that each device is connected to is irrelevant when WWN zoning is configured. An advantage to this type of zoning is that if a port is suspected of being faulty, another port can be used without the need for fabric reconfiguration.
Is there a security vulnerability in soft zoning?
Soft zoning uses filtering implemented in fibre channel switches to prevent ports from being seen from outside of their assigned zones. The security vulnerability in soft zoning is that the ports are still accessible if the user in another zone correctly guesses the fibre channel address.
What are the advantages and disadvantages of WWN zoning?
An advantage to this type of zoning is that if a port is suspected of being faulty, another port can be used without the need for fabric reconfiguration. A disadvantage with WWN zoning is that if there’s a host bus adapter (HBA) failure, the fabric will need to be reconfigured for the host to reconnect to its storage.
