Used NetApp FAS Storage Buying Guide 2026

Last month a client called me panicked—they'd bought a used FAS2720 from a liquidator for $8,500, looked solid on paper, but the NVRAM battery was dead on arrival. A replacement NVRAM module (X5684A) runs $3,200-$4,100 new. When they got it repaired, they'd spent $12,000 total on a unit we'd have quoted at $11,200 in the first place. Lesson learned: buying blind costs more than buying informed. That's where this guide comes in.

The Math: Used FAS vs. New in 2026

A three-year-old NetApp FAS2720 or FAS2820 typically sells in the $10,500-$14,200 range on secondary markets. Brand new? You're looking at $32,000-$38,000 from authorized resellers. That's real money saved—but the catch is runtime reliability and warranty coverage. New gear comes with 5 years of NetWare gold support ($4,200-$6,500 annually). Used units? You get the hardware, nothing else.

For budget-conscious operations, used FAS makes sense if you're deploying as secondary storage, test/dev environments, or archival tier. I've seen used FAS2620 units ($8,900-$11,200) run flawlessly for four years in backup roles. But if this is your production database tier, the $18,000-$25,000 premium for new gear buys you sleep at night.

The FAS3270 (mid-range, 4U dual-controller) sits at $16,400-$19,800 used versus $48,000+ new. The math gets compelling there—but degraded drives and controller firmware mismatches bite hard at that capacity level.

Which Models Hold Up and Which Don't

FAS2620, FAS2720, and FAS2820 are the sweet spot for used buying. I've seen hundreds of these—they're simple enough that third-party engineers can service them, parts are cheap and available, and failure modes are predictable. The FAS2620 (introduced 2016) is starting to feel long in the tooth though; firmware updates are getting sparse, and licensing for newer data management features requires expensive upgrades.

The FAS3170 (released 2018) and FAS3270 are workhorses. Dual AFF controllers, NVMe support, but they run hot and require proper PDU power management. Three-year-old FAS3270 units in the $17,000-$21,000 range are still seeing 8-10 hour repair windows when drives fail—not terrible, but not zero-touch.

Avoid anything older than FAS2600 series (2014-2015 vintage). You'll find FAS2650s and FAS2552s for $5,800-$7,400, but they're entering critical failure age. I don't recommend them unless you're truly desperate for SATA bulk storage and can tolerate 15% annual attrition rates.

Three Failure Modes That Will Cost You

1. NVRAM Battery Degradation (40% of used failures I see)

The NVRAM module (X5684A or X5686A depending on generation) is a supercapacitor-backed memory module designed to protect in-flight writes during power loss. In units over three years old, that supercap degrades. I've measured units at 3.2V when they ship out—spec is 3.6V minimum. They still function, but margins are tight.

Inspection tip: Ask for the system boot log—specifically the "nvram test" output. If you see "supercap voltage: 3.0V" or lower, budget an immediate $3,200-$4,100 replacement. If the seller won't provide logs, assume it's bad and deduct that cost from your offer.

Cost to replace: $3,200-$4,100 plus $800-$1,200 labor if you're not doing it in-house.

2. Drive Shelf Controller Failures (25% of used issues)

FAS arrays ship with drive shelves (DS2246, DS4246, etc.). Those shelves have their own controllers—the IOM6B or IOM6C modules. These handle SAS communication and power management. Three-year-old shelves see IOM controller EEPROM corruption at a 12-15% rate. The first sign is drives not appearing in ONTAP or one shelf dropping offline randomly.

Inspection tip: Log into the FAS web interface and check the "Hardware" view. Every drive shelf should show "Online" status with zero error counts. If you see "Shelf ID not responding" or SAS connection timeouts, the IOM module (X5723A or equivalent, $2,100-$2,800) is dying.

I had a client buy a FAS2720 with four DS2246 shelves—looked great until week two when shelf 3 dropped. Turned out the IOM6B was about to fail. Replacement took three days and cost $2,400 in parts plus remote labor.

Cost to replace: $2,100-$2,800 per IOM module, plus $600-$1,000 in service time.

3. Disk Drive Attrition and Mismatched Firmware (20% of used headaches)

Used FAS units often arrive with a mixed bag of SAS and SATA drives, sometimes from different manufacturers, sometimes with firmware versions two to four revisions old. NetApp is strict about homogeneous RAID groups—mix a 7200 RPM WDC drive with a 10K Seagate, and you'll hit performance walls or data consistency issues.

Inspection tip: Request the output of "storage aggregate show" and "storage disk show" commands. Every drive in a RAID group should be identical model and firmware level. If you see heterogeneous inventory, plan to replace half the drives—expect $400-$600 per drive replacement for a full refresh, plus $1,200-$1,800 in labor to rebuild arrays.

I bought a FAS2820 last year with advertised "24x 1.2TB SAS drives." Actual inventory: 14x Seagate ST1200MM0129, 6x WDC WD1200BB, 4x dead/missing. Total fix-up: $7,200 in drives and rebuild time.

Cost to replace/repair: $400-$1,200 per drive, variable rebuild time.

2026 Price Reality

FAS2620 (used, 3 years): $8,900-$11,200
FAS2720 (used, 3 years): $10,500-$14,200
FAS2820 (used, 3 years): $12,800-$16,400
FAS3270 (used, 3 years): $16,400-$19,800

All figures assume basic configuration (2-controller, single shelf). Add $1,500-$3,200 per additional shelf.

Warranty: Expect zero on secondary market units. Service contracts (if you buy them separately) run $2,200-$3,800 annually depending on response time.

The Right Question to Ask

Before committing to any used FAS, ask yourself: Is this storage tier mission-critical? If yes, buy new or buy a third-party extended warranty ($1,800-$2,600 for 12 months). If it's secondary or non-critical, used FAS at the right price is a legitimate play—just go in with eyes open about repair costs and drive replacement bills.
