Evergreen® Architecture enables upgrading controllers and media in place, across generations, with data-in-place upgrades.
Our contractual SLAs guarantee zero planned downtime for the Purity upgrades and infrastructure expansions we perform. Your platform stays ready as business needs change.
With Everpure Fusion™, automation is set by policy, not a patchwork of scripts that your team has to build and maintain.

The operating model. Everpure runs one Purity operating environment across block, file, and object, with all array software licensed at no additional charge and Everpure Fusion executing policy fleet-wide rather than array by array. One OS to handle, no extra charges, and policies across the fleet: Simple. Efficient. Zero complexity.
NetApp runs three operating systems, ONTAP, SANtricity, and StorageGRID. This is OS-specific automation, and licensing splits between ONTAP One and a separate ONTAP One for SAN bundle for the block-only ASA line.
No. NetApp's Storage Lifecycle Program states that a new controller "will not include storage media." Media is handled separately through Capacity Refresh, a trade-in crediting one terabyte of raw capacity for every four terabytes purchased, and an upgrade may also require buying compatible components. On Everpure, storage media is covered by the Evergreen subscription, including protection against failures due to flash media wear.
Three years, but it requires commitment at least 6 years into their Storage Lifecycle Program (SLP). NetApp's contractual terms define two explicit upgrade windows: after year three (requiring ≥6 years total services) and after year six (requiring ≥9 years total). You also cannot renew SLP past the six-year mark without first completing the year-three update.
Everpure's Ever Modern upgrades arrive every three years upon renewal of Evergreen//Forever. The difference is Everpure doesn’t require purchasing 6 or 9 year commitments to get the upgrades.
Not with Everpure. Evergreen//One includes a No Data Migration SLA. If Everpure determines an upgrade requires a migration rather than a non-disruptive upgrade, the contract credits up to 12 months of charges. NetApp controller upgrades run a six-stage procedure built on aggregate relocation, and non-adjacent ONTAP software upgrades require loading intermediate versions with repeated takeover/giveback operations and reboots.
NetApp Keystone commits to 99.999% (five-nines) availability. The SLA is not automatic: it is "on a nomination basis" for qualified orders. Planned maintenance is excluded from the calculation entirely, no credit is issued. For unplanned outages, credits range from 5% to a hard cap of 50% of capacity fees.
Evergreen//One delivers a 99.9999% (six-nines) availability commitment. The SLA is contractual from day one: no nomination, no opt-in required. If any planned downtime occurs during a Purity upgrade or infrastructure expansion, Everpure pays 100% of the monthly invoice as a credit. For unplanned outages, credits scale from 3% up to 100% of the monthly invoice with no cap.
NetApp's own documentation example: 95 seconds of unavailability affecting 10 TiB of a 100 TiB commitment at $1,000 per month. That breach falls below the 99.999% threshold, triggering a 5% credit rate. NetApp then prorates that rate to the affected fraction of total committed capacity: (10 ÷ 100) × $1,000 × 5% = $5
Run the same scenario through Evergreen//One — same outage, same duration, same $1,000/month subscription. Ninety-five seconds also triggers the 5% credit tier. But Evergreen//One applies that 5% to the full monthly invoice, with no capacity proration: 5% × $1,000 = $50
Same outage. Same subscription cost. Ten times the credit.
The structural difference: NetApp's formula multiplies the credit rate by the fraction of capacity affected, so an incident touching 10% of committed storage returns 10% of what the headline rate implies. Evergreen//One's credits are a percentage of the total monthly invoice regardless of which or how many systems were affected. And the scale differs at the top end too: NetApp's credits cap at 50% of that prorated amount; Evergreen//One's credits reach 100% of the full monthly invoice for outages exceeding 43.8 minutes.
Both NetApp Keystone and Everpure Evergreen//One offer burst headroom. Billing impact on consuming burst will vary based on specific scenarios. However, only Evergreen//One offers an SLA for the buffer which contractually guarantees that headroom exists and provides credits if this guarantee is not met.
