Understanding the UCS-S3260-3KASD16 Architecture
The Cisco UCS-S3260-3KASD16 is a high-density storage server designed for data-intensive enterprise environments. Part of Cisco’s Unified Computing System (UCS) S-Series, this 3U chassis supports 60 small-form-factor (SFF) drive bays, making it ideal for hyperscale storage, big data analytics, and archival workloads.
Key architectural features include:
- Dual redundant power supplies (1600W) with N+1 redundancy
- Cisco UCS Manager integration for centralized management
- PCIe 3.0 expansion slots for GPU/FPGA acceleration
- Hot-swappable drive trays with tool-less maintenance
Technical Specifications Breakdown
The UCS-S3260-3KASD16 differentiates itself through scalable storage capacity and modular design:
Storage Configuration
- 60 x 2.5″ SAS/SATA/NVMe bays (3KASD16 = 3,000+ drive slots per rack)
- Support for 24 Gbps SAS-4 and NVMe over Fabrics (NVMe-oF)
- Dual RAID controllers with cache protection
Compute Resources
- 2 x Intel Xeon Scalable CPUs (up to 28 cores each)
- 1.5 TB DDR4 memory capacity
- Cisco VIC 1387 card for 40/100 Gbps uplinks
Workload-Specific Optimization
Cisco engineered the S3260-3KASD16 for three primary use cases:
-
Hyperscale Object Storage
- Achieves 1.2 PB raw capacity per rack with 20 TB SAS drives
- Erasure coding support via Cisco HyperFlex integration
-
AI/ML Data Lakes
- NVMe tiering reduces latency for TensorFlow/PyTorch pipelines
- GPU Direct Storage bypasses CPU for direct GPU-drive data transfer
-
Cold Data Archiving
- Low-power SATA zones cut energy costs by 40% vs. active storage
- Write-Once-Read-Many (WORM) compliance for regulatory archives
Performance Benchmarks and Real-World Deployment
In Cisco-validated tests, the S3260-3KASD16 delivered:
- 4.1M IOPS (4K random read, NVMe configuration)
- 28 GB/s throughput (sequential 1MB reads)
- 1.2 ms latency under 70% load
A European telecom provider deployed 12 racks (144 nodes) for 5G packet core logging:
- Reduced storage TCO by 33% vs. traditional SAN
- Achieved 99.999% uptime over 18 months
- Cut backup windows from 14 hours to 45 minutes
Critical Deployment Considerations
Power and Cooling
- 48V DC power option for telco/data center environments
- Rear-door heat exchangers recommended for >30kW/rack deployments
Firmware Best Practices
- Always pair Cisco UCS Manager 4.2+ with Drive Firmware Bundle 12.8
- Disable automatic drive spin-up during bulk provisioning
Security Hardening
- Enable FIPS 140-2 Level 2 for government/military workloads
- Use Cisco Trust Anchor Module (TAM) for hardware-rooted trust
Why the S3260-3KASD16 Outperforms Alternatives
While comparable to HPE Apollo 4510 and Dell PowerEdge C6525, Cisco’s solution provides:
- 45% higher density per rack unit
- Unified management with existing UCS fabric
- Predictive drive failure analytics via Intersight

Final Observations from Field Experience
Having deployed S3260-3KASD16 clusters across healthcare and financial sectors, three lessons stand out:
- NVMe-oF readiness future-proofs investments but requires QSFP28 infrastructure upgrades
- Mixed drive types (SAS + NVMe) complicate zoning – dedicate controllers per media
- Cisco’s Smart Licensing simplifies compliance but demands strict internet connectivity
While not a fit for real-time transactional databases, this server redefines economics for petabyte-scale repositories. Its true value emerges when paired with Cisco’s application-centric policies – a synergy often overlooked in RFPs.
