New NetApp platform for ONTAP 9.6 (Part 3) AFF C190

NetApp introduced C190 for Small Business, following the new platform A320 with ONTAP 9.6.

C190

This new All-Flash system has:

  • Fixed format, with no ability to connect additional disk shelves:
    • Only 960 SSD drives installed only in the controller chassis
    • Only 4 configs: with 8, 12, 18 or 24 drives
      • Effective capacity respectively: 13, 24, 40 or 55 TB
    • Supports ONTAP 9.6 GA and higher
    • C190 build with the same chassis as A220, so per HA pair you’ll get:
      • 4x 10Gbps SFP cluster ports
      • 8x UTA ports (10 Gbps or FC 16Gbps)
      • There is a model with 10GBASE-T ports instead of UTA & cluster interconnect ports (12 ports total). Obviously BASE-T ports do not support FCP protocol
  • There will be no more “useful capacity”, NetApp will provide only “Effective capacity”:
    • With dedup, compression, compaction and 24 x 960 GB drives the system provide ~50 TiB Effective capacity. 50 TiB is pretty reliable conservative number because it is even less than ~3:1 data reduction
    • Deduplication snapshot sharing functionality introduced in previous ONTAP versions allows gaining even better efficiency
    • And of course FabricPool tiering can help to save much space
  • C190 comes with Flash bundle which adds to Basic software:
    • SnapMirror/SnapVault for replication
    • SnapRestore for fast restoration from snapshots
    • SnapCenter for App integration with storage snapshots
    • FlexClone for thing cloning.

Fixed configuration with built-in drives, I personally think, is an excellent idea in general, taking into account we have such a wide variety of capacity in SSD drives nowadays and even more to come. Is this the future format for all storage systems with flash? Though C190 supports only 960 GB SSD drives, and new Mid-range A320 system, can have more than one disk shelf.

Fixed configuration allows to manufacture & deliver the systems to clients faster and reduce costs. C190 will cost sub $25k with min config according to NetApp.

Also, in my opinion, C190 can more or less cover market place left after the announcement for the end of sale (EOS) of hardware and virtual AltaVault (AVA, and recently know under a new name “Cloud Backup”) appliances thanks to FabricPool tiering. Cloud Backup appliances still available through AWS & Azure market places. Especially now it is the case after FabricPool in ONTAP 9.6 no longer have a hard-coded ratio for how many data system can store in the cloud compare to hot tier & allows wright-through with “All” policy.

Turns out information about storage capacity “consumed” more comfortable in the form of effective capacity. All this useful capacity, garbage collector and other storage overheads, RAIDs and system reserves are too complicated, so hey, why not? I bet idea of showing only effective capacity influenced by vendors like Pure, which have very effective marketing for sure.

Cons

  • MetroCluster over IP is not supported in C190, while Entry-level A220 & FAS2750 systems support MCC-IP with ONTAP 9.6
  • C190 require ONTAP 9.6, and ONTAP 9.6 do not support 7MTT.
