Question
The storage I/O control layer processes service calls from the command layer or application program and issues commands to the storage I/O control layer to interact with hardware. True or Flase
An FMS provides command-layer functions and utility programs for users and system administrators to manage files, directories, and secondary storage devices. True or Flase
On larger computers such as sewers, a volume can span multiple physical secondary storage devices. True or False
A typical laptop computer has up to a few hundred storage volumes. True or False
The logical view of secondary' storage consists of files contained within folders and storage volumes . True or False
- The technologies that support cloud-based storage services are similar to those used to manage the contents of multilevel primary storage caches.
- disk management system
- storage management system
- file management system
- control management system
- All of the above
- The is______ the part of the kernel that accesses storage locations and manages data movement between storage devices and memory
- disk I/O control supervisor
- storage I/O control layer
- disk I/O control layer
- store I/O control manager
- The_______layer is the bridge between logical and physical views of secondary storage.
- storage I/O control
- file control
- disk control
- block control
- The folder that's currently being accessed is called the______folder
- working
- previous
- next
- index
- The term______describes any architecture with a dedicated storage server attached to a general-purpose network to handle storage access requests from other servers.
- network-attached storage
- storage area network
- network-local storage
- direct attached storage
- Describe RAID 10.
- Logical record grouping in physical records is called_______
Explanation / Answer
1) False
Because File Control Layer processes service calls from command layer or application program and issuses commands to the storage I/O control layer to interact with hardware.
2) True
Because an File Management System provides command-layer functions and utility programs for users and system administrators to manage files, directories, and secondary storage devices and through the command layer user performs common file management functions.
3) True
Because the physical view of secondary storage is a collection of physical storage locations organised as linear address space. A typical computer has upto billions of physical secondary storage locations.
4) False
Because a typical laptop computer has few dozens storage volumes.
5) True
Because users and application programs view secondary storage logically as a collection of files organised in folders and storage volumes.
6) storage management systems
7) storage I/O control layer
8) file control
9) working
10) storage area network
11) RAID 10 :
RAID:(Redundant Array of Independent Disks)
_____________________________________
RAID originally named as Redundant Array of Inexpensive Disks but, now it is named as Redundant Array of Independent Disks.
RAID allows you to improve overall performance in a balanced way by storing the same data redundantly.RAID disk drives are used frequently on servers.
By using RAID the data can be mirrored on more than one disks in the same way, so that if one disk fails the data is preserved in another disks, this preserving technique is known as striping. By using RAID technique you can improve the performance.
A typical RAID provide more storage capacity than a single disk by using multiple disks that appear to be a single device.
Standard RAID levels :
___________________
Level 0: Striped disk array without fault tolerance
Level 1: Mirroring and Duplexing
Level 2: Error-correcting coding
Level 3: Bit-interleaved parity
Level 4: Dedicated parity drive
Level 5: Block interleaved distributed parity
Level 6: Independent data disks with double parity
Level 10: A strip of mirrors
Non- Standard RAID levels:
_______________________
Level 0+1,Level 7, RAID 1E, RAID S.
