Description

The NetApp AFF A800 is NetApp’s flagship **NVMe all-flash storage array**, designed for ultra-low latency, high throughput, and maximum reliability. The system delivers performance suited for demanding enterprise workloads such as AI/ML training, real-time analytics, virtualization, and mission-critical database workloads with end-to-end flash media and advanced data services. 

With the **X93402A controller** (dual-controller HA configuration), the AFF A800 supports up to **48 internal NVMe SSDs** in a 4U chassis, high-availability redundancy between controllers, and robust data services via NetApp ONTAP software. This ensures high uptime and data protection. 

Performance is very strong: the AFF A800 can deliver ultra-low latency (~100 microseconds), throughput up to ~300 GB/s per system, and a scale-out architecture allowing from 2 up to 24 nodes (12 HA pairs) depending on deployment size. 

Connectivity options are flexible: native support for 32/16-Gb Fibre Channel, 100/40/25/10 Gb Ethernet (with autoranging), NVMe over Fabrics including NVMe/FC and NVMe/TCP, plus NAS protocols (NFS, SMB/CIFS), and block protocols (iSCSI, FC). ONTAP software adds data management capabilities such as snapshot, replication (SnapMirror), thin provisioning, deduplication, compression, etc. 

For organizations looking to buy AFF A800, this system is positioned for the highest tiers: enterprises needing high availability, consistency, strong performance at scale, and flexibility in protocol support. It’s suited for data-centers, service providers, AI/ML environments, large virtualization clusters, or unified SAN + NAS deployments.

Key Features

  • Active-Active dual controller (HA) design with X93402A controllers for redundancy and high availability. AFF A800 controller HA
  • 4U chassis with 48 internal NVMe SSD slots for high performance and density. NVMe all-flash storage 
  • Memory: approximately 1.28 TB DRAM (640 GB per controller) plus NVRAM / NVDIMM (≈64 GB total) for cache / log write durability. 
  • High connectivity & protocol flexibility: 32-Gb autoranging Fibre Channel, multiple 100/40/25/10 Gb Ethernet ports, NVMe/FC, NVMe/TCP, FC, iSCSI, NAS protocols. 
  • Scale-out to large clusters: 2-24 nodes (12 HA pairs), supporting thousands of SSDs and very large effective capacities. 
  • Data services via ONTAP: inline deduplication, compression, encryption, snapshots, replication (SnapMirror), seamless upgrades. 
  • Compact form factor and optimized power consumption (median ~1,463W) for enterprise class all-flash.

Compatibility

The NetApp AFF A800 controller is compatible with NetApp NVMe SSDs and supported external shelves (NS224 for NVMe, DS224C etc) for increasing capacity. Users must confirm that drive firmware is supported by ONTAP version installed.

ONTAP software 9.7 RC1 or later is recommended for full feature set and all-flash performance optimizations. Compatibility with Fibre Channel or Ethernet fabric components (switches, HBAs / NICs) should be ensured for autoranging ports (32/16 Gb FC, etc.). 

Environmental and physical compatibility: rack space of 4U, depth ~36.57-92.9 cm with cable management, width approx 19.02-17.6 in depending on flanges, weight up to ~132.5 lbs (≈60.1 kg) depending on configuration. Power and cooling infrastructure should meet requirements (~1,463W median) for optimal performance. 

Usage Scenarios

1) AI / Machine Learning Workloads: AFF A800's NVMe internal SSDs and high throughput make it excellent for training data sets, inference serving, large model storage, and multiple concurrent GPU‐accelerated workflows. Low latency (as low as ~100 µs) helps real-time response. 

2) Enterprise Virtualization / VDI: Use as shared storage for VMware vSphere, Microsoft Hyper-V, Nutanix, etc. High IOPS, redundancy, and multi-protocol support (FC/iSCSI/NFS) make it ideal for performance sensitive and mission-critical virtual workloads.

3) Database Applications & Analytics: OLTP/OLAP databases (Oracle, SQL Server, SAP HANA) benefit from low latency and high throughput. Also for data warehouses or data lakes using NVMe SSDs.

4) Consolidated SAN + NAS File Services: With ONTAP supporting both file (NFS, SMB) and block protocols (FC, iSCSI, NVMe/FC etc.), a single AFF A800 can serve multiple workload types, reducing hardware sprawl.

5) Hybrid Cloud & Multi-Cloud Environments: Using ONTAP’s data mobility features (SnapMirror, Cloud Volumes, etc.) to replicate or tier data to cloud providers, or burst compute into cloud, and take advantage of AFF A800’s performance combined with cloud flexibility.

Frequently Asked Questions

  1. Q: What latency performance can be expected from the AFF A800 under typical production loads?
    A: Under well-balanced, all-flash NVMe workloads and current firmware, latency levels can reach ~100 microseconds for read operations. Write latency depends on SSD type, queue depth, and protocol (FC, NVMe/FC, or NVMe/TCP).
  2. Q: How many nodes can this system scale to, and what is maximum effective capacity?
    A: The AFF A800 supports **2-24 nodes** (up to 12 HA pairs) in a cluster, and can accommodate up to **2,880 SSDs** in large scale-out deployments. Effective capacity depends on SSD sizes and data reduction, but raw capacity can reach hundreds of petabytes. 
  3. Q: What protocols are supported for client connectivity?
    A: AFF A800 supports fibre channel (32Gb and 16Gb), Ethernet (10/25/40/100 GbE), NVMe over Fabric (NVMe/FC, NVMe/TCP), standard block iSCSI, and file protocols such as NFS, SMB/CIFS. This lets you consolidate workloads of different types on one system. 
  4. Q: What are power & physical footprint requirements?
    A: The system uses a 4U chassis, depth ~36.6 in with cable-management, width around 17.6-19.0 inches depending on flanges; weight ~132.5 lbs (≈60.1 kg) in some configurations. Median power consumption about 1,463 Watts. Ensure rack PDUs, cooling, and space meet these specs.
