   • What is Virtual Storage Area Network (VSAN) ?

     VSAN (Virtual Storage Area Network) is a storage solution that is used to create and manage storage for virtual machines. It is intended for usage in scenarios that leverage cloud computing, especially with virtualized infrastructure like VMware vSphere. Centralized storage management is offered by VSAN for virtual machines and applications running in a virtualized environment.

     Storage resources from various physical servers can be combined and shown as a single, shared storage pool using VSAN. The virtual machine disc files (VMDKs) and other data can then be kept in this pool. VSAN dynamically allocates storage for virtual machines according to requirements. It uses distributed architecture and enables IT organizations to pool storage resources and dynamically provide storage to virtual machines on an as-needed basis, VSAN is especially well-suited for cloud computing environments. This can make it simpler to administer virtual environments and lower the expense of obtaining and maintaining real storage.

   • Difference between Storage Area Network (SAN) and Network Attached Storage (NAS)

     Storage Area Network (SAN) is used for transferring the data between the servers and the storage devices’ fiber channels and switches. In SAN (Storage Area Network), data is identified by disk block. Protocols that are used in SAN are SCSI (Small Computer System Interface), SATA (Serial Advanced Technology Attachment), etc. 

     Components of Storage Area Network (SAN):

     • Node ports
     • Cables
     • Interconnect devices such as Hubs, switches, directors
     • Storage arrays
     • SAN management Software 

      Network Attached Storage (NAS), data is identified by file name as well as byte offset. In-Network Attached Storage, the file system is managed by Head units such as CPU and Memory. In this for backup and recovery, files are used instead of the block-by-block copying technique.

     Components of Network Attached Storage (NAS):

     • Head unit: CPU, Memory
     • Network Interface Card (NIC)
     • Optimized operating system
     • Protocols
     • Storage protocols: ATA (Advanced Technology Attachment), SCSI, FC (Fibre Channel)

   • What is WRAN (Wireless Regional Area Network)?

     WRAN which stands for Wireless Regional Area Network is designed and brought to existence, especially for rural areas, developing countries, places with low population density. IEEE 802.22 is the standard developed for Wireless Regional Area Network which uses white spaces of the Radio Frequency (RF) spectrum to provide the broadcast connection in the areas that are difficult to reach. White spaces are the unused part of a frequency spectrum. This is done with the help of cognitive radio (CR) which is designed for wireless systems to CPEs avoid interference and crowding. 

     WRAN is performed in unused channels in the Television (TV) spectrum to get finer propagation of signal at low frequencies. WRAN is the first system that was to regulate the effective use of unused broadbands of the TV spectrum with less interference all around the world.

     Need of WRAN : The prerequisites needed to use frequency spectrum are very high and the use of the entire spectrum is not efficient. A report taken from 2004 to 2005 proclaimed that only 5.2% of the entire spectrum is in use, which called the need to design a network...

   • What is Network Attached Storage?

     In today’s data-driven world, the need for efficient and reliable storage solutions has become paramount for organizations of all sizes. Network-attached storage (NAS) is a cost-effective versatile solution for storing and managing data across networks, allowing centralized storage for multiple users and devices

     NAS devices are special devices or storage servers that are connected to a network, enabling users to access and store data through a local area network (LAN) or wide area network (WAN) Unlike traditional storage solutions which are attached directly to a personal computer, a NAS provides a centralized storage repository that can be accessed by multiple users at the same time

     What is Network Attached Storage(NAS)?

     Network-attached storage (NAS) is a file-based storage architecture that makes stored data more accessible to networked devices means multiple users or client devices retrieve data from a single storage system. As the multiple clients or users connected through a Local Area Network access the data from a centralized disk capacity by Ethernet that’s why it is referred to as Network Attached Storage. Network Attached Storage(NAS) gives all the connected devices of the network a single access point...
