LUN Mapping, Persistent Binding, LUN Masking & Fabric Zoning
***** For Expert Consultation contact me storagetrendz@gmail.com *********
LUN Mapping:
LUN Mapping is host-centric method of storage LUN visibility management. LUN Mapping selectively allows a system administrator to scan for specified SCSI targets and LUNs at storage-driver boot time and to ignore selectively non-specified SCSI targets and LUNs.
The advantage of LUN Mapping is that it provides a level of security management in SANs where LUN Masking is not an option, perhaps because it is not supported
on the storage hardware.
The disadvantage is that LUN Mapping is configured and enabled on a host-by-host basis. It requires good coordination among the administrators of the systems sharing the storage, which ensures that only one host sees certain storage unless planned, as in a clustered server configuration.
Persistent Binding:
It is another host-centric method. This can be implemented in Operating systems (OS) by assigning specific SCSI-Target IDs to the Storage LUNs.
LUN Masking:
LUN Masking is RAID storage subsystem-centric method of LUN visibility management to hosts or servers.
LUN Masking makes sure that each RAID controller is configured to allow each host to see only a subset of the actual LUN's & hide all other LUNs from it. so all connected hosts will see only those LUNs that are assigned to them.
The advantage of LUN Masking is easy to implement in storage subsystems and no changes needed in Hosts or servers that are connected to them.
The disadvantage is multi-vendor devices might be present in the real SAN networks & not all the vendors implemented in same way.
Fabric Zoning:
It is Network-centric method & basically Switch (or Fabric) present in the SAN networks have the capability to allow grouping of Ports from Storage Sub-systems to Connected Hosts in the form of Zoning.
The disadvantage is that Fabric zoning cannot mask individual LUNs that sit behind a port. All hosts connected to the same port will see all the LUNs addressed through that port.
NOTE:
* Each of these Host-centric, Storage centric & switch-centric methods provide their own benifits & drawbacks.
* Usually to provide very good solution, combination of any two methods will be implemented in real SAN networks.

Fabric-side or Switch-side Implimentation in SAN
For More info & your Feedback, contact Email ID: storagetrendz@gmail.com.
FC SAN:
* FC Switch or Fabric in SAN architecture consists of Ports (GBIC or SFP in it), FC protocol stack, Fabric Operating system & Fabric Controller units.
* The Fabric provides basic functionality of connecting multiple Hosts & Storage Sub systems together and manages the communication between them. using Fabric switch topology, about 16 million devices can be connected together in SAN Network.
* Each port on the Swicth is having Unique Address called as World Wide Node Name (WWWN) & World Wide Port Name (WWPN).
* In addition, Fabric provides advanced functionalities as given below,
1. Multi casting & Broad casting services.
2. Name Server Database services.
3. Login Services.
4. Register state Change Notification [RCN] Services.
* Fabric Zoning is the important feature provided by FC switches, By appropriately creating zones and assigning devices [HOST + storage LUNs], an administrator can create a network in which individual hosts cannot access storage devices that are controlled by another host in the FC network.
iSCSI SAN:
* iSCSI Switch or Ethernet Swicth in SAN architecture consists of Ports (ethernet ports), TCP/IP & iSCSI protocol stack, switch software & Controller units.
* The ethernet iSCSi swith provides basic functionality of connecting multiple Hosts & Storage Sub systems together and manages the communication between them.
* Each port on the Swicth is having Unique Address called as World Wide Unique Identifier (WWUI) & there are three different address format, iqn (iscsi Qualifier Name format by CiSCO), eui (Extended Unique Identifier by IEEE), naa (Network Address Authority by T11 organization).
* In addition, Fabric provides advanced functionalities as given below,
1. Uni-Casting, Multi-casting & Any-casting services.
2. Routing Database services.
3. Login Services.
* VLAN Configuration which is similar to Fabric Zoning in FC SAN.
Note:
* More info. on FC Fabric, Zoning & iSCSI Networking will be published in upcoming Posts.
