BSD_Day(2011) - Enclosure Management in FreeBSD, Alexander Motin
SCSI Enclosure Services (SES) permit the management and sense the state of power supplies, cooling devices, LED displays, indicators, individual drives, and other non-SCSI elements installed in an enclosure. SES alerts users about drive, temperature and fan failures with an audible alarm and a fan failure LED.

RAID -Redundant Array of Independent Disks
RAID (redundant array of independent disks) is a way of storing the same data in different places on multiple hard disks or solid-state drives (SSDs) to protect data in the case of a drive failure. There are different RAID levels, however, and not all have the goal of providing redundancy.
-Combination of hard disks to make larger single disk space is called volumes
-raid is not replacement of Backup
RAID Level 0 - Striped volume
-combination of two or more devices
-total size of volume - all disks volume
-even if any one of disk failed , can’t able access data
RAID level 1 - Mirror volume
-combination of 2 disks
-even any one of disk failed, can able to access data
-total size of volume - single volume
-Single disk failure without parity
RAID Level 5: raid5 volume
-Enterprise
-combination of 3 or more disk
-even any one of the disk failed, still can access data
-Single disk failure with parity
-total volume size - 2/3rd of total disk size
RAID 6:
-combination of 5 disk
-Two disk failure with party
-total volume size - ⅗ of total disks size
-even one or two disks failed , still we can access data
RAID 10: raid 1 + raid 0

Ex. internal HDD, SSD, SCSI ,External HDD
-OS , Application,
-easy to install/configure and maintain
-isolated -data -difficult to access from other system
-not centralized storage - local storage
NAS - Network Attached Storage
Access the Shared data through Network
Sharing Data by using protocols
-NFS -Network File System
-CIFS - Common Internet File System
-NFS - Unix/Linux - Unix/Linux
-CIFS - Windows - Linux/Unix
-FTP - also used - but upload or download
CIFS - SAMBA - SMB(Server Message Block)
-easy configure, cheaper than SAN
-not a enterprise solution
-File Level Storage
SAN - Storage Area Network
Redundancy , High Availability
Use Fiber channel - high speed data transmission
Suitable for Enterprise
-Block Level Storage
Use FC or iSCSI protocols
Complex
Costly
LUNs - Logical Unit Number -virtual disk space
HBA - Host Bus Adaptor - like NIC to connect FC
FCoE - Fiber Channel over Ethernet
RAID -Redundant Array of Independent Disks
RAID (redundant array of independent disks) is a way of storing the same data in different places on multiple hard disks or solid-state drives (SSDs) to protect data in the case of a drive failure. There are different RAID levels, however, and not all have the goal of providing redundancy.
-Combination of hard disks to make larger single disk space is called volumes
-raid is not replacement of Backup
RAID Level 0 - Striped volume
-combination of two or more devices
-total size of volume - all disks volume
-even if any one of disk failed , can’t able access data
RAID level 1 - Mirror volume
-combination of 2 disks
-even any one of disk failed, can able to access data
-total size of volume - single volume
-Single disk failure without parity
RAID Level 5: raid5 volume
-Enterprise
-combination of 3 or more disk
-even any one of the disk failed, still can access data
-Single disk failure with parity
-total volume size - 2/3rd of total disk size
RAID 6:
-combination of 5 disk
-Two disk failure with party
-total volume size - ⅗ of total disks size
-even one or two disks failed , still we can access data
RAID 10: raid 1 + raid 0
RAID 50: raid 5 and raid 0
