NetApp and Broadcom recently published a new NetApp® Verified Architecture: a best practice reference architecture that illustrates an optimally configured VMware installation on NetApp ONTAP® 9.6 and Broadcom technology (Emulex 32GB HBAs and Brocade 32GB FC switches). If you manage, administer, or purchase VMware-virtualized configurations or use VMware with SAN or NAS storage, read NVA-1136-Design. You’ll learn about the benefits of an ONTAP and Broadcom SAN that provides storage for your VMware environments, and you’ll see how you can modernize them to:
This NetApp Verified Architecture document, titled “NetApp and Broadcom Modern SAN Cloud-Connected Flash Solution,” explains the advantages of using a NetApp and Broadcom SAN to provide VMware storage for datastores and raw device mappings (RDMs). The document also describes tests that you can easily reproduce. By reading about the test data, configurations, and other details, you can re-create the test environment and obtain the excellent performance results that we observed.
The document also illustrates how to gain other benefits from the solution. For example, it describes:
The real beauty of this solution is that, by using this reference architecture, you can achieve the value proposition and performance gains of ONTAP today. The document lays out configuration details and best practices you can easily use to build your own environment and achieve the same best-in-class performance, availability, scalability, and storage efficiency. The architecture can optimally host any applications or environments you deploy. And because NetApp engineering is constantly testing and analyzing the performance, reliability, and scalability characteristics of ONTAP components, you’ll see performance increases and new capabilities with each ONTAP upgrade, at no additional cost. For example, upgrades from ONTAP 9.2 to 9.3 or later typically saw an iSCSI performance increase of up to 40% because engineering rewrote the ONTAP iSCSI target. A stack rewrite between ONTAP 8.3 and 9 created similar FC Protocol performance gains. In addition to improving performance, NetApp engineering is almost fanatical about hardening ONTAP and cluster resiliency and making fault recovery graceful and nondisruptive.
Although ONTAP supports NVMe/FC today, not all operating systems have updated their initiator stack to add NVMe support yet. But we expect major OS vendors to announce NVMe support in their next operating system releases. For instance, it’s likely that VMware will announce NVMe support in ESX.next at VMworld this year.
Once VMware adds NVMe support, customers that have adopted the configuration (or similar configurations) would, with an ESXi upgrade, be able to improve performance and reduce latency substantially by migrating existing FC Protocol workloads to NVMe. By migrating to NVMe, you’re likely to see these benefits:
