MEM-12KRP-FD512M

MEM-12KRP-FD512M is a flash storage module for Cisco routing equipment.

Flash on a router holds the operating system image, not traffic. That makes its capacity a constraint people meet unexpectedly: software images have grown steadily over the years, and a router with flash sized for the release it shipped with frequently cannot hold a current image, let alone two of them. Having room for two matters, because the safe way to upgrade is to load the new image alongside the old one so there is something to fall back to. A router that can only hold one image turns every upgrade into a one-way decision.

Two practical cautions. Memory for routing equipment is usually not generic: the platform expects a specific part, and generic modules of the right physical type and capacity are often rejected or cause instability that is very hard to attribute. And on older platforms, memory is frequently the component that decides whether an upgrade is possible at all, which makes it worth checking before committing to a software plan rather than after.

Three questions worth answering before any router purchase, whatever the model. What the throughput requirement actually is with your feature set enabled, rather than the datasheet figure measured without it. Whether the features you need are licensed as well as present, since on most platforms security and performance are separate entitlements. And how many slots or ports you will need in three years, because adding capacity is cheap and replacing a chassis is not.

Tell us the platform, the software release you are trying to get to and what is currently fitted, and we will confirm whether this is the right module and whether the upgrade is actually achievable on that hardware.

Green Code Technologies is a supplier of Cisco, and we supply Huawei and Juniper networking alongside HPE, Dell, Samsung, Netgear, Ubiquiti and Asus. We would rather tell you a part is no longer supported, or that we need to check it, than take an order for something that will not do what you need.
