The A9K-40GE-B is a 40-port Gigabit Ethernet Medium Queue line card for the Cisco ASR 9000 Series Routers, built for high-density aggregation, carrier Ethernet, and IP/MPLS edge services, offering line-rate performance and 4GB of DRAM.
The SAS/SATA performance is consistent under heavy IO workloads.
Highly recommend for any data center expansion project.
Great customer support from STC when we had questions about the firmware version.
