Netapp AFF Series:

NetApp’s AFF series ( All-Flash FAS) comes in five models.

Scale from clusters of two to 24 nodes (12 HA pairs) with maximum effective capacities that run up to 700-plus TB per node and the low hundreds of PB (after data reduction) in maximum-sized clusters.

AFF800 is NVMe-equipped, and offers latency under 200µs with claimed end-to-end NVMe connectivity, including over Fibre-Channel.

NetApp’s FAS line:

A set of hybrid flash arrays, with the FAS2700, 8200 and 9000 series.

The SME/mid-size 2700 starts at 10TB and can scale to 17PB in a 24-node cluster. The 9000 scales to 176PB.

Solidfire: The Solidfire all-flash storage product that NetApp acquired in 2015 come in a 1U form factor and three models,

  • H610S-1 each hold 12 flash drives of 960GB, for total capacity of 11.5TB
  • H610S-2 each hold 12 flash drives of 1.92TB, for total capacity of 23TB
  • H610S-4 each hold 12 flash drives of 3.84TB for total capacity of

With data reduction such as data deduplication, compression and thin provisioning , the effective capacity is upped by between 3x and 9x.

Solidfire started out targeted at cloud service providers and is Fibre Channel and iSCSI block storage.

EF- and E-series:

NetApp’s E-Series arrays date back to NetApp’s acquisition of Engenio in 2011, whose arrays were designed for spinning disk. They run the SanTricity operating system, which is a legacy of that pedigree.

There are two all-flash arrays in the series which offer 300,000 IOPS and 1 million IOPS respectively in hardware for 96 and 120 drives, plus maximum raw capacity that goes up to around 1.5PB with expansion shelves.

  • EF280
  • EF570

Meanwhile, there are two spinning disk E-series arrays,

the E5724 with 24 drives and can scale to 120 flash drives and 180 HDDs

the E5760 with 60 drives and can accommodate 120 and 480 of each.
