New NetApp platform & Licensing improvements in ONTAP 9.6 (Part 1)

A320

All flash A320 2U platform introduced, here are a few important details for this new AFF system:

  • From the performance perspective of view most notable is ~100 microseconds latency on SQL SLOB workload. If true, that is a notable improvement because previously we’ve seen only sub 1 millisecond (1,000 microseconds) latency and new latency basically a few times (in the best-case scenario ~10 times) faster
    • About 20% better IOPS performance than A300
  • NVDIMM instead of traditional NVRAM in high-end/mid-range platforms. This is the second NetApp AFF platform after A800 system which adopted NVDIMM instead of PCIe-based NVRAM. Strictly speaking, NVDIMM has been around in entry FAS/AFF systems for an extended period of time, but only because of luck of PCIe slots & space in the controllers
  • No disk drives in the controller chassis
  • No RoCE support for hosts. Yet
  • End to End NVMe
  • Rumors from Insight 2018 confirmed about new disk shelves
    • NS224 directly connected over RoCE
    • 2 disk shelves maximum
    • 1.9 TB, 3.6 TB, and 7.6 TB drives supported
    • With an upcoming ONTAP release disk shelves connected to controllers over a switch will be supported and thus more disk shelves than just two
  • Not very important to customers, but interesting update from engineer theoretical perspective: with this new platform HA and Cluster Interconnect connectivity now combined, unlike in any other appliances before.
  • 8x Onboard 100 GbE ports per controller:
    • 2 for cluster interconnect 100 GbE ports (and HA)
    • 2 for the first disk shelf and optionally another 2 for the second disk shelf
    • it leaves 2 or 4 100 GbE ports for host connection
  • 2 optional PCIe cards per controller with next ports:
    • FC 16/32 Gb ports
    • RoCE capable 100/40 GbE
    • RoCE capable 25 GbE
    • Or 10 Gb BASE-T ports

Entry Level Systems

Previously released A220 system now available with 10G BASE-T ports, thanks to increase popularity of 10G BASE-T switches.

MCC IP for low-end platforms

MCC IP becomes available for low-end platforms: A220 & FAS2750 (not for 2720 though) in ONTAP 9.6 and requires a 4-node configuration (as all MCC-IP configs). New features made in a way to reduce cost for such small configurations.

  • All AFF systems with MCC-IP supports partitioning, including A220
  • Entry-level systems do not require special iWRAP cards/ports like other storage systems
  • Mixing MCC IP & other traffic allowed (with all the MCC-IP configs?)
    • NetApp wants to ensure customers to get great experience with their solutions so there will be some requirements your switch must meet to maintain high performance to be qualified for such MCC IP configuration.

Brief history of MCC IP:

  • In ONTAP 9.5 mid-range platforms FAS8200 & A300 added support for MCC IP
  • In ONTAP 9.4 MCC IP becomes available on high-end A800
  • And initially MCC IP introduced in ONTAP 9.3 for high-end A700 & FAS9000 systems.

New Cluster Switches

Two new port-dense switches from Cisco and Brocade with 48x 10/25 GbE SFP ports and a few 40 GbE or 100GbE QSFP ports. You can use same switches for MCC IP. Here is Brocade-based BES-53248 which will replace CN1610:

And new Cisco Nexus 92300YC with 1.2U height.

NVMe

New OS supported with ONTAP 9.6: Oracle Linux, VMware 6.7, and Windows Server 2012/2016. Previously in ONTAP 9.5 were supported SUSE Linux 15 and RedHat Enterprise Linux 7.5/7.6, RedHat still doesn’t have ANA support. New FlexPod config with A800 connected over FC-NVMe to SUSE Linux. Volume move now available with NVMe namespaces.

NVMe protocol becomes free. Again

In ONTAP 9.6 NVMe protocol become free. It was free when firstly introduced in 9.4 without ANA (Analog for SAN ALUA multipathing), and then it became not free in 9.5.

SnapMirror Synchronous licensing adjusted

In 9.6 simplified licensing, SM-S included in Premium Bundle. NetApp introduced SM-S in ONTAP 9.5 and previously licensed it by TB. If you not going to use a secondary system as the source to another system, SM-S do not need licensing on the secondary system.
