Question
A customer has an environment spanning two data centers in a campus environment The primary storage is an HP 3PARS Storeserv 10400 Storage System. Data is replicated between two sites with RPO of zero. There has flooding the customer was not directly impacted they are now recently been a hurricane and extenseve questioning whether they have adequate protection. You have been brought in to analyze the customer environment and make recommendations. You suggest creating a data center at a remote location and actively replicating the data to it. What are the implications of adding the third data center to the data network? (Select 2)
Options
- AJumbo frames should be enabled
- BThe data network must support OpenStaCk
- CThe data network must support Converged Enhanced Ethernet
- D10 GbE links are needed to interconnect the HP StoreServ 3PAR arrays
- EA new subnet must be added to interconnect the 3PAR arrays

Why each option
Adding a third data center for active data replication to an existing HP 3PAR environment requires specific data network configurations to support the increased traffic and logical separation.
Jumbo frames optimize network performance for large data transfers, such as storage replication, by increasing the Maximum Transmission Unit (MTU) size, which reduces CPU overhead and improves throughput on the data network.
OpenStack is a cloud operating system and is not a fundamental network requirement for interconnecting storage arrays for replication.
Converged Enhanced Ethernet (CEE) or Data Center Bridging (DCB) provides lossless Ethernet for protocols like FCoE, but it is not a universal or mandatory requirement for general IP-based storage replication across data centers.
While 10 GbE links are practically essential for high-performance, zero RPO replication, the question asks for network *implications* which typically refer to configuration or design changes, rather than hardware bandwidth requirements.
Adding a new data center necessitates a new logical network segment (subnet) to provide dedicated IP address ranges for the 3PAR arrays at the new site, ensuring proper routing, isolation, and efficient management of replication traffic.
