Jumbo Frame for Network Challenges
When you in the technical design on the network there will have many different parties will tell you where your server will use the Standard Jumbo Frame payload (MTU 1500) and some will use the huge Jumbo Frame payload (MTU 9000). This is the common number always discussed.
As the Network standard, it will normally use the Standard Jumbo Frame payload (MTU 1500). For the storage vendors always requested to have the Huge Jumbo Frame payload (MTU 9000). Each of them has their own reason to do so. As they want to transport the data between storage to Servers with less Overhead Processing in the Storage Controller and Network Switches Processor.
The bigger Jumbo Frame will be the less payload, but it will have the dark side. The dark side of it is when you have the switches not supported the huge payload it will drop the data packet. This will cause the data transition delay or unstable. This situation it will be only see the network log full of data packet drop and lost.
A lot of upgrade of System Infrastructure will only concentrate on the benefits and not the current environment situations. Later I will show you the challenges of the Jumbo Frame architecture.
As shown above there will have a best setup huge Jumbo Frame payload (MTU 9000) on the Virtual Machine Switches (vSwitches) and the storage also support the huge Jumbo Frame payload (MTU 9000). Both been configured as the best practice for the ISCSI Storage Solution will reduce the Overhead processes. Sadly, the current switches have the challenges where it has challenges in huge Jumbo Frame payload (MTU 9000) architecture and set as standard Jumbo Frame payload (MTU 1500). This normally happen when you have the Standard Layer 2 or Layer 3 Switches. This will cause data transition delay or unstable.
To overcome this you need to get a Layer 2 or Layer 3 Switches where it can support huge Jumbo Frame payload (MTU 9000). That it will reduce the overhead processing and increase performance. This always the ideal design for the Infrastructure Datacenter.
Remember only huge Jumbo Frame payload (MTU 9000) can transport smaller payload than 9000K data where Standard Jumbo Frame payload (MTU 1500) will cause data transition delay or unstable. If you transport huge Jumbo Frame payload (MTU 9000).
