Combined with the industry's first support of NVMe inside and out and NetApp
ONTAP data management software, AFF A800 all-flash systems accelerate, manage,
and protect your business-critical data with the industry's highest
performance, superior flexibility, and best-in-class data management and cloud
integration. By combining low-latency NVMe solid-state drives (SSDs) and the
first NVMe over Fibre Channel (NVMe/FC) connectivity, the AFF A800 delivers
ultra-low latency and massive throughput, and scales up to 24 nodes in a
cluster.
The FlexGroup feature of ONTAP 9 enables massive scaling in a
single namespace to over 20PB with over 400 billion files while evenly
spreading the performance across the cluster. This makes the AFF A800 a great
system for engineering and design applications as well as DevOps. It is
particularly well-suited for chip development and software builds that are
typically high file-count environments with high meta-data traffic.

| 1 | 3.84 TB NVMe SSDs used for data and storage operating system; used to build three RAID-DP RAID groups per storage controller node in the cluster | RAID-DP | Yes | 192 |
| 2 | 960GB NVMe M.2 device, 2 per HA pair; used as boot media | none | Yes | 8 |
| Number of Filesystems | 1 | Total Capacity | 447.7 TiB | Filesystem Type | NetApp FlexGroup |
|---|
The single FlexGroup consumed all data volumes from all of the aggregates across all of the nodes. In order to support the high number of files required by the benchmark, immediately after creation the default inode density of the FlexGroup was adjusted using the 'volume modify' option '-files 8000000000'.
The storage configuration consisted of 4 AFF A800 HA pairs (8 controller nodes
total). The two controllers in each HA pair were connected in a SFO (storage
failover) configuration. Together, all 8 controllers (configured as 4 HA Pairs)
comprise the tested AFF A800 HA cluster. Stated in the reverse, the tested AFF
A800 HA cluster consists of 4 HA Pairs, each of which consists of 2 controllers
(also referred to as nodes).
Each storage controller was connected to
its own and partner's NVMe drives in a multi-path HA configuration.
All
NVMe SSDs were in active use during the test. In addition to the factory
configured RAID Group housing its root aggregate, each storage controller was
configured with two 21+2 RAID-DP RAID Groups. There were 2 data aggregates on
each node, each of which consumed one of the node's two 21+2 RAID-DP RAID
Groups. 8x volumes, holding benchmark data, were created within each aggregate.
"Root aggregates" hold ONTAP operating system related files. Note that spare
(unused) drive partitions are not included in the "storage and filesystems"
table because they held no data during the benchmark execution.
A
storage virtual machine or "SVM" was created on the cluster, spanning all
storage controller nodes. Within the SVM, a single FlexGroup volume was created
using the two data aggregates on each controller. A FlexGroup volume is a
scale-out NAS single-namespace container that provides high performance along
with automatic load distribution and scalability.
| Item No | Transport Type | Number of Ports Used | Notes |
|---|---|---|---|
| 1 | 25 GbE and 100 GbE | 64 | For the client-to-storage network, the AFF A800 Cluster used a total of 16x 100 GbE connections from storage to the switch, communicating via NFSv3 over TCP/IP to 48 clients, via one 25 GbE connection to the switch for each client. MTU=9000 was used for data switch ports. The benchmark was conducted in a large shared-infrastructure lab; only the ports shown and documented were used on the Cisco Nexus C9516 switch for this benchmark test. |
| 2 | 100 GbE | 16 | The Cluster Interconnect network is connected via 100 GbE to a Cisco C3232 switch, with 4 connections to each HA pair. |
Each NetApp AFF A800 HA Pair used 4x 100 GbE ports for data transport connectivity to clients (through the Cisco C9516 switch), Item 1 above. Each of the clients driving workload used one 25GbE port for data transport. All ports on the Item 1 network utilized MTU=9000. The Cluster Interconnect network, Item 2 above, utilized MTU=9000. All interfaces associated with dataflow are visible to all other interfaces associated with dataflow.

Each of the 8 NetApp AFF A800 Storage Controllers contains 2 Intel Xeon 8160 processors with 24 cores each; 2.10 GHz, hyperthreading disabled. Each client contains 1 Intel Xeon E5-1630 processor with 4 cores at 3.70 GHz, hyperthreading enabled.
| Description | Size in GiB | Number of Instances | Nonvolatile | Total GiB |
|---|---|---|---|---|
| Main Memory for each NetApp AFF A800 HA Pair | 1280 | 4 | V | 5120 |
| NVDIMM (NVRAM) Memory for each NetApp AFF A800 HA pair | 128 | 4 | NV | 512 |
| Memory for each client; 47 of these drove the workload | 64 | 48 | V | 3072 | Grand Total Memory Gibibytes | 8704 |
Each storage controller has main memory that is used for the operating system and caching filesystem data. Each controller also has NVRAM; See "Stable Storage" for more information.
The AFF A800 utilizes non-volatile battery-backed memory (NVRAM) for write caching. When a file-modifying operation is processed by the filesystem (WAFL) it is written to system memory and journaled into a non-volatile memory region backed by the NVRAM. This memory region is often referred to as the WAFL NVLog (non-volatile log). The NVLog is mirrored between nodes in an HA pair and protects the filesystem from any SPOF (single-point-of-failure) until the data is de-staged to disk via a WAFL consistency point (CP). In the event of an abrupt failure, data which was committed to the NVLog but has not yet reached its final destination (disk) is read back from the NVLog and subsequently written to disk via a CP.
All clients accessed the FlexGroup from all the available network
interfaces.
Unlike a general-purpose operating system, ONTAP does not
provide mechanisms for non-administrative users to run third-party code. Due to
this behavior, ONTAP is not affected by either the Spectre or Meltdown
vulnerabilities. The same is true of all ONTAP variants including both ONTAP
running on FAS/AFF hardware as well as virtualized ONTAP products such as ONTAP
Select and ONTAP Cloud. In addition, FAS/AFF BIOS firmware does not provide a
mechanism to run arbitrary code and thus is not susceptible to either the
Spectre or Meltdown attacks. More information is available from
https://security.netapp.com/advisory/ntap-20180104-0001/.
None of the
components used to perform the test were patched with Spectre or Meltdown
patches (CVE-2017-5754,CVE-2017-5753,CVE-2017-5715).
ONTAP Storage Efficiency techniques including inline compression and inline deduplication were enabled by default, and were active during this test. Standard data protection features, including background RAID and media error scrubbing, software validated RAID checksum, and double disk failure protection via double parity RAID (RAID-DP) were enabled during the test. WARMUP_TIME has been set to a value of 600 seconds.
Please reference the configuration diagram. 48 clients were used to generate the workload; 1 client acted as Prime Client to control the 47 other clients. Each client used one 25 GbE connection, through a Cisco Nexus C9516 switch. Each storage HA pair had 4x 100 GbE connections to the data switch. The filesystem consisted of one ONTAP FlexGroup. The clients mounted the FlexGroup volume as an NFSv3 filesystem. The ONTAP cluster provided access to the FlexGroup volume on every 100 GbE port connected to the data switch (16 ports total). Each cluster node had 2 Logical Interfaces (LIFs) per 100GbE Port, for a total of 4 LIFs per node, for a total of 32 LIFs for the AFF A800 cluster. Each client created mount points across those 32 LIFs symmetrically.
