DCI Impact on Applications

§ Ultra-Low Latency across DC for SAN/NAS/HPC = Higher Performance for all the applications

• Lower Total Cost of Ownership “Less Number of servers/reduced DAS needed in each DC- Low CAPEX” and lower OPEX (Power/Cooling) and less Network elements to manage

§ Facilitates Vmotion beyond Data Centre (long distance “live” migration)

• <= 5ms latency requirement • > 10GigE

• Move critical applications out of Disaster Way (Disaster Recovery) § Load Balancing across Data Center and better utilization of resources

§ Shared SAN across Data Centers

§ Improves BB Credits limit i.e. better utilization of FC channel bandwidth § Long distance Vstorage move

Inefficient DCI/Cloud Connects side

Effects

§

Poor applications performance

• More HPC and Storage need to be added to each DC

• Poor Utilization of resources across the data center

due to lack of real-time clustering and load sharing

• Redundant resources across the Data Center to

address the peak loads scenarios in each DC, which

can be avoided using High Performance DCI since it

enables resources across DC to be shared as if they

are next to each other.

• CPU spends significant cycles waiting for IO

transaction to complete instead of processing the

applications/transactions

Current approach

§ Add multiples ports on Routers and add additional wavelength across the DC if team was able to isolate the issues is related to DCI

• Most of the time its hard to isolate the issue to DCI and first point of attack is let’s add additional servers, memory,

storage etc.

§ DC Interconnect without ultra low latency does not improves the performance much

• Servers/VMs still spend significant amount of cycles 50% waiting for IO transactions to complete or retry after time-out § DC Interconnect with ultra low latency not only improves the

performance of the IO transaction significantly but also improve the overall transaction rate significantly so less numbers of VM resources needed reducing both CAPEX and OPEX

Right Solution

§

Ultra Low Latency across the DC i.e. no

significant latency addition beyond the fiber

delay

• Better performance achieved from all the DC

infrastructure low CAPEX for HPC/SAN and lower

OPEX power due to load sharing and better

utilization less number of servers, LAN ports

needed

§

Packet Optical solutions to minimize the

numbers of wavelength and routers ports
