Question: Can the same object in ECS be accessed by different protocols?
CAS objects are only accessible by their own API. NFS and Dell Atmos can access each other’s created objects using path-based style. S3, NFS, and Swift can interoperate such that objects created in any of these protocols can be accessed by any one of them as well.
Question: How does ECS work with Hadoop?
ECS supports the Hadoop S3A client for storing Hadoop data. S3A is an open source connector for Hadoop, based on the official Amazon Web Services (AWS) SDK. It was created to address storage scaling and cost problems that many Hadoop admin were having with HDFS. Hadoop S3A connects Hadoop clusters to any S3 compatible object store.
Question: What is the API connection limit?
All the REST APIs (S3, Atmos, Swift) go through an http server component called netty. The effective limit for REST protocols has been 1000 active connections per node.
For the CAS API, it has a maximum of 600 active connections per node.
