Question
A medium sized manufacturing company decides to build a redundant vSphere 5.1 Infrastructure cluster with HP BladeSystem. As their consultant, you propose redundant HP BladeSystem c7000 Enclosures for their local and remote sites. The storage solution you propose is an HP Store Virtual 4000 with remote replication. To stay within the budget, you decide to use the HP StoreVirtual VSA at the remote site. Which feature of the VSA must you consider for future growth?
Options
- Amaximum 10 TB per VSA
- Bmaximum 3 VSAs per site
- Cmaximum one LAN adapter per VSA
- Dmaximum one VSA per host

Why each option
The HP StoreVirtual VSA enforces a hard maximum capacity of 10 TB per instance, which is the critical scalability constraint to account for when planning future storage growth at a remote site.
The HP StoreVirtual Virtual Storage Appliance (VSA) supports a maximum of 10 TB of storage capacity per VSA instance. This ceiling is the primary growth limitation because once that threshold is reached, an additional VSA must be provisioned and clustered, affecting both the cost model and architectural complexity of the remote site.
There is no three-VSA-per-site restriction in the HP StoreVirtual VSA architecture - multiple VSA instances can be federated into a cluster at a single site, so the number of VSAs per site is not the binding growth constraint.
The HP StoreVirtual VSA supports multiple LAN adapters for network connectivity and iSCSI access, so a one-adapter-per-VSA restriction does not apply and is not a consideration for future growth planning.
Multiple HP StoreVirtual VSA instances can be deployed on a single physical host, so a one-VSA-per-host limitation does not exist and is not the relevant capacity constraint to evaluate for growth.
