D-RP-OE-A-24 Exam Dumps - EMC Data Protection Questions and Answers

In Dell EMC RecoverPoint, virtual RPAs (vRPAs) use iSCSI protocol for connections. This is because vRPAs are designed to operate in virtual environments where iSCSI is commonly used for storage networking due to its ability to work over standard IP networks.Physical RPAs, such as Gen-5 and Gen-6, typically use Fibre Channel (FC) for direct storage connectivity1.

Here’s a breakdown of the connectivity:

vRPA: Utilizes iSCSI for connections to protected storage. This is suitable for virtualized environments where the RecoverPoint for Virtual Machines (RP4VMs) operates.

Gen-5 and Gen-6 RPAs: These are physical appliances that generally use Fibre Channel for connectivity, which is more common in physical data center environments where dedicated storage networks are present1.

It’s important to choose the correct RPA type based on the storage infrastructure and connectivity requirements of the environment1.

In a Dell RecoverPoint environment, Direct Access mode allows for write access to a replica volume during testing or other scenarios. However, when using XtremIO arrays, Direct Access mode is not available because XtremIO handles replication differently compared to other array types.Instead, XtremIO uses its snapshot technology, which does not support Direct Access in the same way as traditional replication methods1.

Here’s why Direct Access is limited with XtremIO:

XtremIO Snapshot Technology: XtremIO arrays use snapshot technology for replication, which is different from the replication methods used by other array types like VMAX, VNX, or VPLEX.

Direct Access Mode: This mode typically allows a replica volume to be mounted and written to directly, but due to the way XtremIO handles snapshots, this functionality is not supported.

RecoverPoint Integration: RecoverPoint integrates with XtremIO to provide replication and disaster recovery solutions, but the Direct Access feature is not compatible with XtremIO’s snapshot-based replication1.

Therefore, when using XtremIO arrays in a RecoverPoint environment, administrators need to be aware of this limitation and plan their disaster recovery and testing strategies accordingly1.
