Global Next Generation Data Storage Technologies Market: Set to Grow Exponentially by – Forecast 2022

Data Storage Evolution

• Have you had any idea as to how much of our primary data is properly organized

• Only 15 to 20% of the data is structured !!! Else is not !!

• Occupation of less space, resulting in less time being wasted

• Most of the unstructured data is reportedly old or obsolete data

4

Data Explosion Problems

• Data does not suddenly explode instantly. It is accrued over time & we don’t keep track of it!!

• Typically, 40 % or more enterprise data is inactive, but …• It consumes expensive storage capacity

• It gets managed, backed up , replicated …

• It has significant legal & compliance risks

• It all has to be recovered in a DR scenario

Something to Think about …

• 5TB of total data in one year can translate in a decade or less to …

• 115 TB of active data

• 77 TB of inactive data

Cloud Virtualization Benefits

What is Cloud Computing

• Cloud Computing is a style of computing where massively scalable IT-related capabilities are provided as a service across the Internet to multiple external customers

• Cloud computing: A pool of abstracted, highly scalable, and managed infrastructure capable of hosting end-customer applications and billed by consumption

• Cloud computing is web-based processing whereby shared resources, software and information are provided to computers and other devices on demand over the Internet.

Fiber Channel AdvantagesPrice performance leadership– FC delivers cost-effective solutions for storage and networks

Scalability– From single point-to-point gigabit links to integrated enterprises with hundreds of servers, FC delivers unmatched performance

Multiple topologies– Dedicated point-to-point, shared loops, and switched topologies

Multiple protocols– FC delivers data; SCSI, TCP/IP, video, or raw data can all take

advantage of high-performance, reliable FC technology

Freedom from congestion– FC’s credit-based flow control delivers data as fast as the destination device is able to receive it

SAN – Putting It all Together

Fibre Channel Port Types

24

Buffer-to-buffer credit• This type of flow control deals only with the link:

• – Between an N_Port and an F_Port, between two E_Ports, or between

two N_Ports (P2P)

• – Each port on the link exchanges values of how many frames it is

• willing to receive at a time from the other port

• This value becomes the BB_Credit value for the other port

End-to-end creditEnd-to-End flow control is not concerned with individual links,

but rather the source and destination N_Ports

• Concept is very similar to buffer-to-buffer flow control

– When relationship between two N_Ports is established, each reportshow many receive buffers are available for the other port

• This value becomes the EE_Credit value for the other port

25

Fiber Channel: Frame structure

Name and Addressing Convention

26

Worldwide Node NameA unique identifier for each Fiber Channel device

– This is similar to the way each Ethernet card has a unique MAC address

Each device in the SAN is identified by a unique node world

wide node name (WWNN) containing:

– A vendor identifier field, which is defined and maintained by the IEEE

– A vendor-specific information field defined by the vendor

Each N_Port will have its own world wide port name (WWPN)

Worldwide name addressing scheme

27

Port addressAnother addressing scheme is used in Fibre Channel networks

– This scheme is used to address ports

Each port has its 24-bit address

– This uses a smaller frame header

– Can speed up the routing process

A 24-bit addressing scheme

– Allows for almost 16 million addresses

Some relationship is needed between the 24-bit address and the 64-bit address associated with WWPN

24-bit port address = FCID Identifier

Fiber Channel- Fabric ServicesManagement services

• Services allow data to be passed from device to management platforms

• Management suite can have a view of the entire SAN

Time Services

• Management of fabric-wide expiration timers or elapsed time values Simple Name Server (SNS)

• Maintained and updated by all switches in the fabric

• Allows a node to register itself and pass on critical information, such as upper layer protocols supported

Login Services

• A node communicates with the login server in order to do a fabric login

Registered State Change Notification (RSCN)

• Propagates information about a change of the state of one node to all other nodes

Routing mechanism: FSPFFSPF picks best path

– Keeps track of the links on all switches in the fabric and associates a cost with each link

The path selected is the one with lowest cumulative cost, source to target, through the fabric

– Default link cost is calculated to be inversely proportional to bandwidth

Lowest cost is the best path with equal cost paths load balanced up to four equal costpaths (some vendors support more)

How FSPF works?

– Creates a topology database built on the collection of link states

Including a cost for all switches in a fabric

– The topology is kept in all switches in the fabric and synchronized via ISL links

– An update mechanism is used when there is a link state change

How FSPF helps?

– In case of unequal cost multiple routes, FSPF ensures that the route with the

lowest cost regardless of hops is used

– It prevents loops and converges very quickly

SAN Major Design Factors

34

Choosing the Right Solution

Basics• Scalability• Performance• Availability

Specifics• Thin Provisioning• Data Copy• Replication• De-duplication

Costs• Price• Upgrade• Support

Storage Tiering IssuesMajor Questions to be Asked

•Backups and restores took less than 10 seconds

• Entire servers were replicated to another place (not just user databases, but everything included

• You could boot up the backup and test stuff

• You could copy backups to tape without slowing SQL

• The SAN automatically figured out what needed to be on SSD.

35

RAID Challenges

Automated tiering puts the hot data on fast drives

Automatic Tiering

• Automatic Tiering Specifics depend on each vendor’s mapping strategy• Block-level tiering puts the hot blocks on fast drives

• LUN-level tiering moves you entire LUN (drive letter)

• The speed depends on your wallet• Gotta buy enough space in different tiers

• Gotta know who belongs on which tier (and what doesn’t belong on your fast tier)

36

RAID Levels –RAID 0

RAID 0 – disk stripingData is divided into block and distributed

across drives in arrayTwo disks used most often (half data on each disk)No redundancyIf either disk fails, all data is lost

RAID Levels – RAID 1

RAID 1 – Mirroring and duplexingData duplicated on a 2nd diskMirroring uses a single drive

controller, duplexing uses 2

Data redundancy exists If either drive fails, data can be

read from or written to the other drive

No Performance improvement

37

RAID Levels – RAID 2

RAID 2An array of disks where data is striped at bit level across all

disks in arrayError correctionStored on muliple parity disksHigh performance and error recoveryCurrently not used as modern drives, have error correction

RAID Levels – RAID 3RAID 3 – striping with parity

Data striped at byte level on separatedrives

Parity (error detection and correction code)stored on another dedicated parity disk

If any drive in array fails, data isrecovered with remaining blocksplus parity information (read andwrite conitinues)

Improved read times with large chunks of data (video)

Rarely used

38

RAID Levels – RAID 4RAID 4

Similar to RAID 3 except data is striped at block rather than byte level

Higher read performance than RAID 3

Writer performance worse because of single parity drive

Not often used

RAID Levels – RAID 5RAID 5 – striping with distributed parity

Data divided into even number of blocks, and with additional parity block, striped across odd number of disks

If any one drive fails, data recovered with remaining blocks and parity information

Read/write continues until you replace drive

Improved read/write because blocks are read/written simultaneously

39

RAID Levels – RAID 6

RAID 6Similar to RAID 5 except two

parity drives are used instead of one (permits recovery from two drive failures)

Similar performance benefits

Faster recovery after failure of single drive

RAID 10 (mirroring) Adds a Redundant Copy

40

Block Storage Vs Object Storage

Why Object Storage

41

Object Storage Benefits

•Build scale-out storage by adding more servers

•High reliability by duplicating content across nodes

• Easy to manage (no need to know about RAID or volumes)

• Standard API as all solutions support S3 API, no vendor lock-in

•Cost effective: mix SSDs (small but fast) and SATA (slow but large)
