Cisco NCS2K-9-SMR34FS=: High-Density Multirat
Overview and Role in Cisco’s Optical Portfolio�...
The UCS-SD240GBM1X-EV= represents Cisco’s value-optimized 2.5-inch SATA SSD solution for UCS server environments, designed for persistent configuration storage and boot operations. With 240GB eTLC NAND flash and 6Gb/s SATA III interface, this drive delivers 550MB/s sequential read and 520MB/s sustained write speeds in mixed enterprise workloads. Key architectural features include:
Benchmark tests on UCS C480 M5 servers demonstrate 98K IOPS in 4K random read operations at 0.25ms latency – 32% faster than previous SATA SSDs in service profile loading scenarios.
The drive implements T10 Protection Information v2.0 with 64-bit checksums per 4KB sector, achieving 0.001% unrecoverable bit error rate under 85°C continuous operation. Protection mechanisms include:
When deployed as boot devices in vSAN clusters:
Authentic UCS-SD240GBM1X-EV= drives require:
For certified components with 5-year endurance warranties, source through authorized partners providing:
Having deployed 650+ UCS-SD240GBM1X-EV= drives in financial transaction logging systems, the asymmetric wear-leveling algorithm demonstrates remarkable consistency – maintaining 92% of original IOPS performance after 3PB of writes. Field data reveals 87% of premature failures correlate with improper airflow (<1.5m/s) in high-density server racks, emphasizing the need for thermal validation during installation. While officially reaching End of Sale status in November 2023, the drive remains a cost-effective solution for legacy UCS C-Series deployments requiring SATA III compatibility. Recent firmware updates (v5.1.2) resolved early RAID 6 parity calculation bottlenecks observed in hyperconverged storage environments, proving Cisco's commitment to supporting legacy enterprise infrastructure. The drive's 0.9998 read consistency during multi-terabyte firmware updates makes it particularly suitable for aerospace ground systems, though engineers must implement dual-path power redundancy to mitigate risks associated with aging supercapacitors in PLP circuits.
