1. What is SAN?
SAN Stands for Storage Area Networks. It has an accelerates data access for sharing storage resources with advanced management features
2. Mention the limitations in Direct Attached Storage Technology (DAS)?
DAS has several limitations like it is unable to scale and share resources .It has several I/O bottlenecks with limitations in length of the cable.
3. What are the different hardware components in SAN?
Cable, SAN, Switch, GBIC, Storage subsystem and Host Bus Adapters are the different components in SAN.
4. Describe key features of Fibre channel?
The Key features of Fibre channel are High speed, Long distance, Fast access Data backup, Improved performance and Data travel within the SAN.
5. Define FC-AL?
FC-AL Stands for Fibre Channel-Arbitrated Loop .It links up to 126 ports together on a single shared simplex media.
6. What is Switched Fabric Topology?
Switched Fabric topology permits multiple simultaneous transmissions from source to destination between pair of nodes connected to it.
7. Mention two different types of SAN switches we are using at present?
Brocade and Mc Data are the two types of SAN switches which we are using at present.
8. How do you measure the speed of port?
By using command #show port2 we can measure the speed of port.
9. What is LUN masking?
LUN Masking is nothing but hiding the LUN to specific server or Host.
10. What are the different ways of improving operational efficiencies of consolidating storage?
The Different ways of improving operational efficiencies of consolidating storage are scalability, back/restore and centralized administration.
11. What ways does SAN provides High availability infrastructure?
The Different ways providing high availability infrastructure of SAN are No single point failure, Backup/restore and improved replication from distance point of view.
12. How do you accomplish best RAID Configurations?
We can accomplish best RAID configurations
Based on several factors like number of users along with size of data & application criticality, storage requirements cost.
13. What is the use of multi pathing?
Multi pathing is best used for security and load balancing.
