Storage Resources (Part 2)

Q1. What is File Server Resource Manager?
  • File Server Resource Manager is a suite of tools for windows Server that allows administrators to control, manage, and understand the quantity and type of data stored on their server.
Q2. What is Share and Storage Management?
  • Share and Storage Management provides a centralized location to manage the following server resources
  1. Folders and volumes that are shared on the network
               2.  Volumes in disks and storage subsystems


Q3. What is the use of Storage Explorer?
  • Storage Explorer is used to view and manage the Fibre Channel and iSCSI fabrics that are available in your Storage Area Network (SAN)
Q4. What is the use of Storage Manager for SANs?
  • Storage Manager for SANs is used to create and manage Logical Unit Numbers (LUNs) on Fibre Channel and iSCSI disk drive subsystems that support Virtual Disk Service (VDS) in SAN.
Q5. What is LUN?
  • LUN is logical reference to a portion of a storage subsystems. It consists of a disk, a section of a disk, a whole disk array, or a section of a disk array in the subsystem.
Q6. What is Disk Management?
  • Disk Management is a utility for managing hard disks and the volumes or partitions. It helps in initializing disks, creating volumes, and formatting volumes with the File Allocation Table (FAT), FAT32, or New Technology File System (NTFS) file systems.
Q7. How many types of dynamic volumes are there?
  • Simple
  • Spanned
  • Striped
  • Mirrored
  • RAID-5
Q8. What are Spanned disk volumes?
  • Spanned disk volumes combine areas of unallocated space from multiple disks into one logical volume. They require minimum of two disks; however, you can use up-to 32 disks
Q9. What is striped disk volume?
  • Striped disk volumes are made up of stripes of data of equal size written across each disk in the volumes. They are created from equally sized, unallocated areas on two or more disks. If one of the disks containing a striped volume fails, the entire volume fails, and all data on the striped volume becomes inaccessible. 
Q10. What is mirrored volume?
  • A mirrored volume provides a copy of a volume on another disk. This is a fault-tolerant volume, which provides data redundancy by duplicating the information contained on the volume. The two disks that make up a mirrored volume are known as mirrors.
Q11. What is RAID-5 volume?
  • RAID-5 volumes are available only on computers running the Windows 200 Server family or Windows Server 2003. It stripes data and parity across three or more disks. Parity is a calculated value used to reconstruct data if one disk fails. When a disk fails, Windows Server 2003 continues to operate by recreating the data that was on the failed disk from the remaining data and Parity.
