The correct answer is A. A new subnet must be added to interconnect the 3PAR arrays. Adding a third remote data center for active data replication with HP 3PAR arrays necessitates careful network planning for connectivity and bandwidth.
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 recently been a hurricane and extensive flooding the customer was not directly impacted they are now questioning whether they have adequate protection. You have been brought in to analyze the customer environment and make recommendations. You suggest creating a DR 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
- AA new subnet must be added to interconnect the 3PAR arrays
- 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

Why each option
Adding a third remote data center for active data replication with HP 3PAR arrays necessitates careful network planning for connectivity and bandwidth.
When adding a new data center with 3PAR arrays for replication, dedicated network interfaces on each array require specific IP addressing. A new subnet is essential to logically separate and correctly route replication traffic between the new remote 3PAR array and the existing ones, facilitating proper network design and security.
OpenStack is a cloud management platform and its support is not a fundamental network requirement for establishing 3PAR array replication between data centers. While 3PAR can integrate with OpenStack for storage provisioning, the underlying data network itself doesn't inherently need to 'support OpenStack'.
Converged Enhanced Ethernet (CEE) or Data Center Bridging (DCB) provides lossless Ethernet capabilities, often used for Fibre Channel over Ethernet (FCoE). While 3PAR supports FCoE, it's not a mandatory requirement for IP-based replication to a remote DR site, which often uses standard Ethernet for Remote Copy over IP.
