The switch comes with both front-to-back and backto- front airflow options for energy efficiency. All SFP+ ports accommodate a full range of 10GbE twinax copper cables and optical 1/10GbE transceivers. With Arista EOS, advanced monitoring and provisioning capabilities such as Zero Touch Provisioning, VMTracer and Linux based tools can be run natively on the switch.

Deep Buffer Architecture

The Arista 7048 switches are designed to handle fair allocation of bandwidth to all traffic flows in the datacenter. With 768 MB of packet buffer memory, the architecture scales in congestion scenarios and all ports can simultaneously buffer up to 50ms of traffic without any drops. The deep buffer architecture of the 7048 also provides a platform for lossless asymmetric connections when 10GbE nodes communicate with 1GbE nodes in the datacenter.

Automated Provisioning Tools

The 7048T-A offers advanced capabilities for automating deployment and bring up of data center racks. Zero Touch Provisioning allows switches to download configuration and image files from any connected network port allowing managers to set up remote data center switches as they would bare metal servers.

Arista Network’s vmTracer is an agent that works with vmWare’s vCenter data center manager to automate VLAN configuration to vSwitches and VMs on hypervisors. As VMs are instantiated, cloned or moved on the network, The 7048T-A automatically reconfigures VLANs trunking to the server and cleans up unnecessary configurations which can jeopardize the security of stability of the data center network.
