Arista DCS-7048T-A-F

Arista DCS-7048T-A-F 7048-A 48-port 100/1000BASE-T, 4 (1/10GbE) sfp ports, ZTP, front-to-rear air.

The Arista 7048 switch offers unmatched performance for high-density data center deployments. With 48 100/1000BASE-T and four 1/10GbE SFP+ ports, the switch delivers a non-blocking design with 40 Gbps of uplink bandwidth. The 7048 switch forwards at layer 2/3/4 with low latency at wire speed. Redundant power and cooling options along with a robust software architecture provide the foundation for a data center class product. The switch comes with both front-to-back and back- to-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.

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.
