Cabling for Software-Defined Storage

Suppliers of IT infrastructures are establishing the principle of Software-Defined Storage (SDS) on the market. They are integrating storage into the server infrastructure. This virtualization has consequences for cabling in the server room.


The Road to 40/100 Gigabit Ethernet

Increasing virtualization means data traffic between servers is growing. At the same time, there is an increase in CPU and PCI performance. These advances should also get through to users who expect acceptable transmission speed and latency. The road leads to 40/100 Gigabit Ethernet. This speed can only be attained with appropriately configured cabling.

At the same time as storage is shifted into the server housing, networks are consolidated (see figure). Cabling density increases, as a result, both at the server housing and at the switch or router.

These both need to be considered when planning the infrastructure of the data center.

Preparing networks

The evolution of networks described can only be successfully implemented with more bandwidth and greater cabling performance. As a result, data centers have to ensure their networks can cope with using 40/100 Gigabit Ethernet (GbE).
