Technical Specifications and Design Philosophy
The Cisco E-SSD-U2N-4TB= is a 4TB enterprise-grade solid-state drive (SSD) designed for data-intensive workloads in modern data centers. Built on the U.2 (2.5-inch) form factor and NVMe 1.3 protocol, it delivers sequential read speeds up to 3,500 MB/s and write speeds up to 3,000 MB/s, according to performance benchmarks from itmall.sale. Unlike consumer SSDs, this drive features Power Loss Protection (PLP), which safeguards data during unexpected outages, and a 2 DWPD (Drive Writes Per Day) endurance rating, making it suitable for write-heavy applications like database logging.
Key hardware specs:
- Interface: PCIe Gen3 x4
- Latency: <100μs (read), <150μs (write)
- MTBF: 2 million hours
- Operating temperature: 0°C to 70°C
Compatibility with Cisco Infrastructure
A critical concern for enterprises is whether the E-SSD-U2N-4TB= integrates with existing Cisco hardware. The drive is certified for:
- Cisco UCS C-Series and B-Series servers (e.g., UCS C240 M5/M6)
- HyperFlex HX-Series nodes for hyperconverged storage
- UCS Director and Intersight for centralized management
However, it is not backward-compatible with SATA-only systems like older UCS M4 servers. For hybrid environments, Cisco’s NVMe-oF (NVMe over Fabrics) support enables pooling these drives across clusters.
Performance vs. Traditional Storage
To quantify its value, let’s compare the E-SSD-U2N-4TB= against a 4TB SATA SSD (e.g., Cisco’s E-SSD-SATA-4TB):
| Metric | E-SSD-U2N-4TB= (NVMe) | E-SSD-SATA-4TB (SATA) |
|---|---|---|
| Sequential Read Speed | 3,500 MB/s | 560 MB/s |
| Random IOPS (4K) | 750,000 | 98,000 |
| Latency | 90μs | 450μs |
The 6x faster read speeds and 5x lower latency make the U.2 NVMe drive ideal for AI/ML training datasets, real-time analytics, and VMware vSAN deployments.
Use Cases and Operational Advantages
1. Virtualization and Cloud Workloads
The drive’s low latency ensures smooth performance in VMware ESXi or Kubernetes clusters, where rapid access to virtual disks is critical. For example, a single E-SSD-U2N-4TB= can host 50–60 VMs with moderate I/O demands.
2. Database Acceleration
Oracle DBaaS and SAP HANA deployments benefit from sustained write speeds, reducing transaction commit times by 30–40% compared to SATA alternatives.
3. Edge Computing Resilience
With PLP and broad temperature tolerance, this SSD is suited for IoT gateways or remote branch offices lacking climate-controlled environments.
Deployment Best Practices
- Thermal Management: Ensure 1U/2U servers have adequate airflow to avoid throttling.
- RAID Configuration: Use hardware RAID controllers (e.g., Cisco UCS VIC 1457) for redundancy.
- Firmware Updates: Sync drive firmware with Cisco’s Hardware Compatibility List (HCL) quarterly.
Where to Source Authentic Drives
Counterfeit Cisco storage components remain a industry-wide issue. For guaranteed compatibility and warranty coverage, purchase the E-SSD-U2N-4TB= exclusively through authorized partners like itmall.sale’s Cisco storage portfolio.
Final Perspective: Why This SSD Matters
Having analyzed its architecture and real-world applications, the E-SSD-U2N-4TB= isn’t merely a storage upgrade—it’s a strategic enabler for latency-sensitive digital transformation projects. While the upfront cost is higher than SATA drives, the TCO (Total Cost of Ownership) over five years drops by ~25% due to reduced replacement cycles and energy efficiency. For enterprises standardizing on Cisco UCS or HyperFlex, skipping this NVMe-tier storage risks creating performance bottlenecks that no amount of CPU or RAM can mitigate.
