Which Companies Will Offer E3-enabled Products?

While E3 form factors began with a focus on traditional enterprise server and storage use cases, hyperscalers are evaluating E3 for use in scale-out environments. Many server, storage and SSD companies with 2.5-inch storage solutions are aligned with the E3 Family. Vendors currently working on the SFF-TA-1002 and SFF-TA-1008 specifications include Dell EMC^®, HPE, KIOXIA and many others. Initial development and demonstration systems in support of the E3 Family of form factors are well underway with early full function development vehicles as shown (Figure 1).
