Learn about ASA r2 storage systems

The ASA r2 systems deliver a unified hardware and software solution that creates a simplified experience specific to the needs of SAN-only customers.

The following ASA platforms are classified as ASA r2 systems:

  • ETERNUS AX1300 ASA

  • ETERNUS AX2300 ASA

  • ETERNUS AX4200 ASA

  • ETERNUS AC2200 ASA

ASA r2 systems support all SAN protocols (iSCSI, FC, NVMe/FC, NVMe/TCP). The iSCSI, FC, NVMe/FC and NVMe/TCP protocols support symmetric active-active architecture for multipathing so that all paths between the hosts and storage are active/optimized. The iSCSI and NVMe/TCP protocols support direct paths between the hosts and storage.

On an ASA r2 system, ONTAP software and ONTAP System Manager are streamlined to provide support for essential SAN functionality while removing features and functions not supported in SAN environments.

ASA r2 systems introduce the use of storage units with consistency groups:

  • A storage unit makes storage space available to your SAN hosts for data operations. A storage unit refers to a LUN for SCSI hosts or an NVMe namespace for NVMe hosts.

  • A consistency group is a collection of storage units that are managed as a single unit.

ASA r2 systems use storage units and consistency groups to simplify storage management and data protection. For example, suppose you have a database consisting of 10 storage units in a consistency group, and you need to back up the entire database. Instead of backing up each storage unit individually, you can protect the entire database by backing up the consistency group.

To help secure your data against malicious attacks such as theft or ransomware, ASA r2 systems support an on-board key manager, dual-layer encryption, tamper-proof snapshots, multi-factor authentication and multi-admin verification.

ASA r2 systems do not support cluster mixing with current ASA or ETERNUS AX/AC/HX series.
