Question
A customer is inquiring about expanding their primary cluster consisting of six S-Series nodes in order to improve performance. They have a second cluster with 11 X-Series nodes. Both clusters leverage 1GbE, but the customer recently installed a 10GbE network that can be utilized. They also have multiple Fibre Channel SAN arrays in their environment. They have a variety of workloads on each cluster and are in the process of determining which workloads belong on which cluster. They have discovered that one of the workloads- a SQL database that resides on the X-Series node cluster - is experiencing timeouts due to latency. The database vendor has suggested limiting latency to 5ms or less to eliminate these timeouts. How do you advise the customer?

- BMerge the S-Series nodes and X-Series nodes into one cluster, upgrade the 1GbE to 10GbE, and
- CSuggest the customer consider leveraging SSDs in the new nodes they purchase and GNA to
- DRecommend they increase the amount of DRAM in the cluster or consider an Accelerator node in
