NotepadStorage Device Configuration

Storage Types and Configurations


Redundant Array of Independent Disks(RAID)

File System Types


Disk Types and Configurations:

-Removable Media

-Interface Types

-Access Speed

-Solid-State Drive(SSD)




Removable Media


-Floppy Disks

-USB Drive

-Can be fixed or non removable


Interface Types

-Advanced technology attachment(ATA)

-Integrated drive electronics(IDE)

-Serial ATA(SATA)

-Serial attached SCSI(SAS)

-Small computer system interface(SCSI)


Access Speed

-Hard disk Speed


-Access Time


Solid State Drive(SSD)

-Contains no moving parts

-High performance storage device


USB Drive

-Plug and play removable storage

-Assigned a drive letter on Windows OS

-Powered by the USB port if small

-Requires an external power supply for larger hard drives

-Best of temporary transfers and storage



-Requires a device to read the magnetic tape

-Used primarily for backup data

-Primarily a means of keeping monthly or yearly full backups

-Slow seek time

-Used for off-site storage





-Performance Levels of Each Tier



Performance Levels of Each Tier

-Tier 1-Mission critical

performance,capacity,reliability and manageability

-Tier 2-Major business applications

Needs to be reasonably fast

-Tier 3-financial data

Not accessed often,inexpensive

-Tier 4-Stored e-mails or data for long periods

Large amounts of data can be slower than the others



-Used for fitting data in each tier

-Policy to migrates between tiers

-Provide guidelines to manage the organization’s data

-Service License Agreement(SLA)

NotepadStorage Device Configurations part 2


-RAID 0(Striped)

-RAID 1(mirrored)

-RAID 0+1(striped+striped=becomes mirrored)

-RAID 1+0 or 10(mirrored+mirrored=becomes striped)

-RAID 5(Block level stripping with distributed parity)

-RAID 6(Block-level stripping with distributed parity and an additional parity block)


File system Types

-Byte Size

-Unix File System

-New Technology File System

-File Allocation Table

-Virtual Machine File System

Unix File System(UFS)

-Primary file system for unix based os

-uses a hierarchical file structure

-top level is called the root


max volume:1 YB

max files size:32 PB

No encryption


New Technology File System (NTFS)

-Created by Microsoft

-Supports features such as:


-volume shadow copy service(vss)

-encryption file system(efs)




Max files size:16 TB

Yes Encryption


File Allocation Table(FAT)

-Legacy file system

-Used primarily by removable media

-Does not support features for permissions and encryption


Max volume 2tb

max files 4gb

no encryption


Virtual Machine File System(VMFS)

-Used with VMware ESX server and vSphere

-Stored disk images and snapshots in a file

-Allows server to read and write simultaneously


Max volume:64tb

Max File Size:2TB

No encryption


Z File System 

Created by Sun microsystem

-file system and logical volume manager

-protects against data corruption

-supports high storage capacities




No encyption


-Extended File System








No encryption
