​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.
