​​Architectural Design & Hardware Specifications​​

The ​​Cisco UCS-SD38TKA1XEV-D=​​ represents Cisco’s fourth-generation enterprise storage solution optimized for ​​high-density SAS/SATA hybrid environments​​ in UCS C480 M5/M6 server platforms. Built on ​​2.5-inch dual-port SAS 12Gbps architecture​​, this SSD combines three critical innovations for mission-critical deployments:

• ​​Kioxia KumoLite 3D TLC NAND​​: Delivers ​​3.8TB raw capacity​​ with 3 DWPD (Drive Writes Per Day) endurance through dynamic wear-leveling algorithms validated for 144-hour continuous RAID 5 rebuild operations.
• ​​Thermal Velocity Boost​​: Operates at ​​-5°C to 60°C ambient temperatures​​ with adaptive throttling that maintains <0.15ms latency under 70% sustained write loads.
• ​​RAID 0/1/5/6/50/60 Compatibility​​: Certified for ​​Cisco UCS 12G SAS Modular RAID controllers​​ with 8GB cache, supporting hot-swap deployment in C480 M5 front-loading drive bays.

Third-party benchmarks demonstrate ​​4.3x higher random read performance​​ versus 15K RPM SAS HDDs in Oracle OLTP workloads.

​​Performance Benchmarks & Protocol Optimization​​

In standardized tests using Cisco UCS C480 M5 servers with VMware vSphere 8.0:

The ​​Adaptive Read Disturb Management 3.1​​ extends NAND lifespan by 43% through voltage threshold adjustments based on real-time P/E cycle telemetry.

​​Enterprise Security Implementation​​

Building on Cisco’s ​​Secure Storage Framework 4.3​​, the SSD implements:

1. ​​FIPS 140-3 Level 2 Encryption​​:

   ucs-storage# enable ssd-tpm  
   ucs-storage# crypto-self-test frequency 48  

   Features:

   • AES-256-XTS hardware acceleration with 15μs encryption latency
   • Instant Secure Erase (ISE) for full 3.8TB sanitization in <9 seconds

2. ​​Runtime Integrity Monitoring​​:

   • 1GB DRAM cache with ECC protection against silent data corruption
   • Power-loss protection capacitors rated for 60J energy backup

3. ​​Multi-Tenant Isolation​​:

   Security Layer	Performance Impact
   SAS Domain Encryption	<1.1%
   SED Sanitize Command	<0.7%

This reduces attack surfaces by 96.8% compared to software-encrypted alternatives.

​​Hyperscale Deployment Strategies​​

For optimal integration with Cisco HyperFlex 5.5 clusters:

hx-storage configure --ssd-profile ucs-sd38tka1xev-d --raid-tier platinum  

Critical parameters:

• ​​1:5 HDD-to-SSD ratio​​ for tiered storage acceleration
• ​​Sub-55μs latency​​ for metadata operations in distributed file systems
• ​​Adaptive Caching​​: 5.7x IOPS improvement for small-block random reads

Real-world financial database deployments demonstrate:

• ​​99.6% storage utilization​​ for encrypted transaction logs
• ​​0.25ms P99 latency​​ during peak trading periods
• ​​82% reduction​​ in Cassandra cluster rebuild times.

​​Procurement & Lifecycle Management​​

​​itmall.sale​​ provides ​​Cisco-certified UCS-SD38TKA1XEV-D= solutions​​ with:

• ​​7-Year Endurance Warranty​​ covering premature wear-out scenarios
• ​​Bulk Deployment Kits​​ for 100+ drive implementations
• ​​Firmware Crossgrade Tools​​ supporting v3.2 to v6.4 migrations

Implementation checklist:

1. Validate ​​NX-OS 10.3(2)F+​​ for SAS 12Gbps link aggregation
2. Maintain ​​≥2RU vertical spacing​​ between drive sleds
3. Configure ​​Dynamic Thermal Balancing​​ at 90% of rated power capacity

​​The Paradox of Enterprise Flash Economics​​

While 30.72TB QLC drives dominate capacity discussions, the UCS-SD38TKA1XEV-D= demonstrates that ​​thermal-aware SSD architectures achieve 8:1 $/IOPS efficiency​​ versus all-flash arrays. Its 99.3% uptime metric at 60°C ambient conditions reveals a critical insight – enterprise storage reliability now depends more on firmware-driven thermal optimization than raw component specifications. For organizations modernizing legacy SAN/NAS infrastructures, this drive represents not just a performance upgrade – it’s a thermodynamic optimization engine converting thermal constraints into operational predictability.
