Description

This 64GB DRAM memory module is built for the Cisco Catalyst 8500 Series Edge Platforms. It suits network teams running large WAN, SD-WAN and internet-edge deployments that need more control-plane headroom, larger routing tables or containerised services on the router.

At 64GB it is the maximum DRAM capacity supported on the C8500 platform. The C8500-12X and C8500-12X4QC ship with 16GB by default and can be upgraded to 32GB or 64GB, while the C8500-20X6C uses 64GB as its default memory. On the C8500-20X6C, 64GB supports 7M IPv4 and 7M IPv6 routes, compared with 4M IPv4 and 4M IPv6 routes on platforms running 16GB. The extra memory also gives containerised services such as ThousandEyes agents, which need more than 8GB of DRAM, room to run alongside routing.

The module is a field-replaceable DIMM and is ordered as MEM-C8500-64GB, with the spare ordered as MEM-C8500-64GB=. It is for the Catalyst 8500 family only. The Catalyst 8500L platforms use separate part numbers, MEM-C8500L-32GB and MEM-C8500L-64GB, so this module is not interchangeable with them.

Enquire with XS Network Tech for new or used pricing and availability.

FAQs

Q: Which platforms does MEM-C8500-64GB fit?
A: It is for the Cisco Catalyst 8500 Series Edge Platforms: C8500-12X, C8500-12X4QC and C8500-20X6C. The C8500-20X6C uses 64GB as its default memory.

Q: Can I use it in a Catalyst 8500L?
A: No. The Catalyst 8500L platforms use separate part numbers, MEM-C8500L-32GB and MEM-C8500L-64GB, and this module is not interchangeable with them.

Q: Does the memory module need a licence?
A: No licence is required for the memory module itself. The host router uses Cisco DNA subscription licensing.

Q: How does it differ from MEM-C8500-32GB?
A: This module provides 64GB, the maximum DRAM the C8500 platform supports. MEM-C8500-32GB provides 32GB.

Q: Does it need separate power?
A: No. It is a passive component powered from the host chassis, and the datasheet gives no separate power draw.
