Expert Analysis
All three are six-nines all-flash platforms, but they target different points in a UK buyer's refresh cycle. The HPE Nimble AF60 is the oldest design here and is approaching end-of-service-life (HPE has published EOSL dates around 2028 for many AF/HF models), with SAS/SATA SSDs, 10GBASE-T onboard networking and a 553 TB raw ceiling per array. It remains a dependable block-storage workhorse with excellent InfoSight analytics and all-inclusive licensing, but it is not an end-to-end NVMe platform and should only be considered where an existing Nimble estate, InfoSight familiarity or budget constraints dominate — not for a long-horizon investment.
Pure Storage FlashArray//X R5 and NetApp AFF A70 are both current-generation, end-to-end NVMe systems and are the right candidates for a multi-year refresh. The FlashArray//X is the strongest fit for pure block/SAN consolidation: its Evergreen model removes disruptive forklift upgrades, Purity is famously simple to operate, SafeMode snapshots ship on by default for ransomware resilience, and it supports the full NVMe-oF stack (FC, RoCE, TCP). The //X90 R5 reaches up to 4.4 PB effective in a compact 3U–9U footprint, making it efficient on rack space and operations for teams that want set-and-forget storage.
The NetApp AFF A70 is the most capable and most expandable of the three: true unified storage (block, file, S3) on ONTAP, 48 internal NVMe slots in 4U, up to 6.6 PB raw per HA pair, PCIe 5.0 I/O, 64Gb FC and up to 16×100GbE per HA pair, plus 24-node NAS scale-out and DGX SuperPOD certification for AI pipelines. For UK organisations consolidating mixed NAS/SAN workloads, virtualisation, databases and emerging AI/GenAI data services under one OS, the A70 offers the widest envelope and the longest growth runway — at the cost of greater configuration complexity than Pure's deliberately minimal approach. Servnet can quote and configure any of the three vendor-neutrally.
Frequently asked questions
Which is best for unified NAS and SAN consolidation?
The NetApp AFF A70 is the only true unified system here, serving block, file and S3 on ONTAP with up to 24-node NAS scale-out. The Pure FlashArray//X and HPE Nimble AF60 are primarily block-oriented, though the //X also supports NFS and SMB.
Which platform supports end-to-end NVMe?
Both the Pure FlashArray//X R5 (NVMe DirectFlash, NVMe/FC, NVMe/RoCE, NVMe/TCP) and the NetApp AFF A70 (NVMe SSDs, NVMe/FC, NVMe/TCP) are end-to-end NVMe. The HPE Nimble AF60 uses SAS/SATA SSDs and is not an NVMe platform.
What are the key capacity differences?
The AF60 tops out at 553 TB raw / ~2 PB effective per array, the FlashArray//X90 R5 reaches 1,207 TB raw / 4.4 PB effective, and the AFF A70 scales to 6.6 PB raw per HA pair and up to 330 PB effective across a 24-node cluster.
Should refresh timing influence the choice?
Yes. The HPE Nimble AF60 is an older design with published end-of-service-life dates around 2028, whereas the Pure FlashArray//X R5 and NetApp AFF A70 are current-generation NVMe systems better suited to a long-horizon investment. Servnet can quote all three.
