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
– IP Based
– NFS
