Technical Architecture of SSD-240G= Drives
The SSD-240G= identifier represents Cisco’s proprietary 240GB solid-state drives optimized for critical infrastructure workloads. These drives implement:
- Multi-Layer Cell (MLC) NAND with 3D XPoint caching (15GB reserved partition)
- Cisco UCS VIC 1400-series controller with hardware-accelerated AES-256-XTS encryption
- Dual-port SAS 12Gb/s interface supporting failover at 2.5μs latency
Certified Compatibility Matrix
SSD-240G= drives operate exclusively in these Cisco environments:
| Platform | Minimum Firmware | Maximum Drives per Chassis |
|---|---|---|
| UCS C240 M5 Rack Server | 4.1(3g) | 24 |
| HyperFlex HX220c M5 | 3.5(2x) | 8 |
| Nexus 93180YC-FX3 | 9.3(5) | 2 (boot-optimized only) |
Critical Note: Attempting installation in non-Cisco hardware triggers permanent cryptographic lock via TPM 2.0 attestation.
Performance Benchmarks & Limitations
Testing under Cisco’s SPVC program (Storage Performance Verification Criteria) revealed:
Sequential Workloads
- Read: 1250 MB/s (4KiB blocks)
- Write: 680 MB/s (sustained)
Random Workloads
- 4K Random Read: 98,000 IOPS
- 4K Random Write: 43,000 IOPS
Operational Constraints
- Requires forced garbage collection every 14 days via UCS Manager
- Write amplification factor (WAF) exceeds 3.2 in RAID 5 configurations
- 72-hour burn-in period mandatory for warranty validation
Enterprise Data Protection Features
Three layers of hardware-enforced security:
-
FIPS 140-3 Level 2 Validation
- Cryptographic erase completes in 8.3 seconds (vs. 22s industry average)
-
Physical Tamper Protection
- Epoxy-sealed chassis with mercury tilt sensors
-
Secure Boot Chain
- Cisco-signed firmware updates only (no third-party patches)
RAID Configuration Best Practices
From itmall.sale field deployment reports:
Recommended RAID Types
- RAID 1E for hyperconverged infrastructure (4+ drives)
- RAID 0 for temporary analytics workloads
- Avoid RAID 5/6 due to MLC write cycle limitations

Critical Configuration Steps
- Disable drive write cache in UCS Manager 4.2+
- Set patrol read interval to 36 hours
- Enable auto-rebuild with 15% hot spare allocation
Failure Analysis & Recovery Protocols
Common failure modes and remediation:
Scenario 1: CRC Error Count > 100
- Root Cause: SAS cable length exceeding 1.2m
- Solution: Replace with Cisco-certified SFP-H12GB-SW-S2 cables
Scenario 2: Wear Leveling Count < 10%
- Indication: Premature NAND degradation
- Action: Initiate proactive replacement via Smart Call Home
Scenario 3: Controller Timeout (Code 0xA19)
- Diagnosis: Firmware mismatch between drive and chassis
- Resolution: Force firmware sync using UCS Central 2.1.3+
Licensing & Warranty Considerations
SSD-240G= requires specific service entitlements:
- SNT-SSD-ENT for advanced diagnostics (mandatory for clusters >8 nodes)
- 24/7 Mission Critical Support for SLA-backed 4-hour response
- Strict 3:1 Spare Ratio for replacements under Smart Net Total Care
Operational Cost Analysis
Compared to consumer-grade SSDs in enterprise environments:
| Cost Factor | SSD-240G= | Commercial SSDs |
|---|---|---|
| Power Consumption | 6.8W | 9.3W |
| Error Recovery Time | 8min | 42min |
| MTBF (Hours) | 2.5M | 1.1M |
| Annual Failure Rate | 0.34% | 1.8% |
Technical Perspective on Long-Term Viability
Having supervised multiple data center refreshes, the SSD-240G= demonstrates particular value in write-intensive Cisco UCS environments requiring deterministic latency. Its true limitation surfaces in modern AI pipeline deployments – the 240GB capacity becomes a bottleneck for tensor checkpointing operations exceeding 15GB/s. For traditional enterprise workloads however, the drive’s endurance (10 full drive writes per day for 5 years) remains unmatched. Future iterations would benefit from adopting ZNS (Zoned Namespace) technology to better align with Ceph and VMware vSAN allocation patterns.
