3 TYPES OF DATA STORAGE

Block – Raw device with no functional organizational structure

– physical location of blocks of bits on media

– Organizational structure provided by application layer – file system, data base etc.

File – Hierarchical structure based on storing meta-data and

pointers to locations on the media

– Designed for human interaction (browsing) but suitable for machine / application interaction

Object – Flat organizational structure with pointers to locations

on media with meta-data stored with the object.

– Designed for machine / application access

– Application has to remember where objects are stored

– No direct way for humans to browse.

Block:

FC (Fibre Channel), FCoE, IP Ethernet, iSCI

File: IP Ethernet

Object: IP Ethernet

AVAYA POV ON STORAGE NETWORKING

IP Networking is extending it’s presence in storage – 1Gb and 10Gb iSCSI today, moving to 40Gb

– “New” deployment options are IP centric – Big Data / Analytics – distributed workloads

– SDS – Vmware VSAN, Nutanix, Nexenta, MS StorageSpaces

– NAS data is growing faster than block data – Primary files shares, cloud storage, Virtualized workloads

– Object storage is IP Network based – Repository for the largest data stores.

FCoE is a bridge technology – Allows customers (and vendors) to extend the value of their FC investment

– Most server connections today are 2, 4, or 8Gb – 16Gb predominate for aggregation / array connections

– “New” FCoE/FC customers are rare

– Migration to iSCSI will be slow, but will happen

DATA CENTER DESIGN – PAST

Looks like a campus design

– Large chassis aggregation and core switches

– L2 stops at aggregation

Oversubscription

– 4:1 to 10:1 typical

End-of-Row or Top-of-Rack

Large chassis inefficient

Data flow North-South

© 2016 Avaya Inc. All right reserved 18

DATA CENTER DESIGN – TODAY

Leaf-Spine, Clos, Fat Tree

Leafs only connect to spine

Campus, WAN, etc., all connect to border leaf

Typically blocking

– 2:1-8:1 oversubscription typical

Why did we build this?

– Extend L2 across data center

– Price

– Consistent performance

© 2016 Avaya Inc. All right reserved 19

TRAFFIC IN DATA CENTER

Three (3) types of traffic

– Management

– Interactive (Users to Applications)

– Machine to Machine

Mgmt Interactive Machine to Machine

© 2016 Avaya Inc. All right reserved 20

TRAFFIC IN DATA CENTER

Management traffic

– Configuration/Monitoring (light weight)

– vMotion (VM resiliency)

– L2 network requirements

– > 1G

– Resilient

Interactive traffic

– User generated

– Typically light weight

– VDI/3D heavier

Machine to Machine traffic

– Database transactions (chatty)

– Storage (heavy)

– NAS (NFS based)

– Fiber channel only (obsolete)

– Fiber channel over Ethernet (migrating)

– Typically isolated

© 2016 Avaya Inc. All right reserved 21

NETWORK VIRTUALIZATION

Management Virtual Server Network (VSN)

– Layer 2

– Stealth

Interactive VSN

– L2 within DC

– Virtual Router @ DC, Campus boundary

– Outstanding Real-time and Multicast

Machine to Machine traffic VSN

– High-speed Storage VSN

– Optimized for
