Question
A customer has an environment spanning two datacenters in a campus environment. The primary storage is an HP 3PAR storeServ 10400 Storage system. Data is replicated between sites with and RPO of zero. There has recently been a hurricane and extensive flooding. While the customer was not directly impacted, they are now questioning wether 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 data to it. What are the implications of adding the third data center to the data network? (Select two)
Options
- AJumbo Frames should be enabled
- BThe data network must support converged enhanced ethernet
- CA new subnet must be added to interconnect the 3PAR arrays
- DThe data network must support Open Stack
- E10 GbE links are needed to interconnect to HP 3PAR StoreServ Arrays

Why each option
Adding a remote third datacenter for HP 3PAR replication requires new network subnetting for addressing and enabling Jumbo Frames for efficient data transfer over the network.
Enabling Jumbo Frames significantly improves the efficiency of data transfer for large storage blocks over IP networks, reducing CPU overhead and increasing throughput, which is critical for efficient remote storage replication.
Converged Enhanced Ethernet (CEE) is specific to enabling technologies like FCoE and lossless Ethernet; while beneficial for unified networks, it is not a mandatory or general requirement for all IP-based 3PAR replication to a remote site.
When extending a storage network to a new, distinct remote datacenter, a new logical network segment (subnet) is typically required to properly address and segment the 3PAR array's replication interfaces at that location.
OpenStack is a cloud platform for management and orchestration, and while 3PAR can integrate with it, its support is not a direct implication for the underlying data network used for array-to-array replication.
While 10 GbE links are essential for high-performance storage replication, the customer already has RPO=0 replication between two datacenters, implying high-speed links are already used; this is a capacity requirement rather than a new architectural implication of adding a third site.
