• 5H3XX: This is a Dell part (hard drive) number, often tied to enterprise SAS disk drives used inside SCv series systems.

Together, they imply the use of the 5H3XX drive inside a Dell SCv2020 storage chassis or system.

Dell SCV2020 5H3XX: Overview of the Storage System

Dell SCV2020 5H3XX System Architecture & Specs

The Dell SCv2020 is part of the SCv2000 / SCv2020 storage family which offers compact, scalable storage arrays.

Key architectural highlights:

• Supports up to 24 hot-swappable 2.5-inch SAS drives

• Uses redundant, hot-swappable storage controllers (up to 2 controllers)

• Offers front-end connectivity options: Fibre Channel, iSCSI, or SAS depending on configuration

• Back-end SAS expansion capabilities to link additional enclosures (SC100 or SC120)

• Power and cooling are handled in modules: dual power supply / cooling fan modules

Because of its compact form and flexibility, SCv2020 is suited for mid-range storage environments, often in enterprises that need high performance but in a smaller physical footprint.

Use Cases & Deployment Scenarios

Some common use cases for SCv2020 include:

• Virtual machine storage (VMware, Hyper-V)

• Database workloads (small to medium)

• General file / block storage for business apps

• Backup / archival tiers (especially when mixed drive types are used)

• Hybrid setups combining SSD + spinning disk

Its modular nature means you can start with a smaller set of drives and expand later.

5H3XX Drive: Specs & Role

What is 5H3XX?

Part number 5H3XX corresponds to a Dell Compellent / SC-series enterprise SAS drive, typically:

• 1.8 TB capacity

• 10,000 RPM rotational speed

• 12 Gb/s SAS interface (SAS-3)

• 2.5-inch / small form factor (SFF) size

• Enterprise class (often labeled “Enterprise Plus”) controller’s management.

Compatibility & Target Arrays

The 5H3XX drive is commonly used in Dell Compellent / SC series arrays, including:

• SCv2020

• SCv3020 / SCv420 / SCv5020 / SCv7020 (in some configurations)

Always verify firmware compatibility and array support lists, as enterprise storage arrays often require certified drive firmware to ensure reliability and performance.

How SCv2020 & 5H3XX Work Together

Storage Layout & RAID Strategy

In an SCv2020 chassis using 5H3XX drives, data is laid out by the system’s Storage Center OS (Dell’s software layer). Some important points:

• The system may use thin provisioning, automated tiering, and data movement between drive tiers.

• You can mix drives (e.g. faster SAS or SSD) in certain tiers depending on your performance needs.

• RAID settings are managed at the controller level, and the system ensures redundancy.

Because 5H3XX is a high performance drive (10K, SAS-3), it is often part of the performance tier in hybrid arrays.

Performance & Throughput

Given 12 Gb/s SAS interface and 10,000 RPM speed, a 5H3XX drive is capable of solid performance in random I/O and sequential workloads (within mechanical limits). However:

• The effective throughput will depend heavily on queue depth, workload type (random vs sequential), and controller / caching strategy.

• For workloads demanding very high IOPS, multiple drives in parallel are essential.

• The controller, cache, and interconnect (front-end ports) must not choke the system.

In a balanced system, the SCv2020 with 5H3XX drives offers a capable mid-tier performance envelope.

Advantages & Limitations of SCv2020 5H3XX Setup

Advantages

• Enterprise-grade reliability: Both SCv2020 and 5H3XX are built for enterprise use.

• Scalability: You can expand via enclosures (SC100 / SC120) and more drives.

• Flexibility in connectivity: Supports multiple protocols (Fibre Channel, iSCSI, SAS).

• Moderate footprint: 2.5-inch format and compact design help when rack space is limited.

• High throughput drive: 10K SAS drives are faster than typical 7.2K ones, good for mixed workloads.

Limitations & Considerations

• Mechanical drive constraints: Being a spinning disk, latency and seek time will be nontrivial for random workloads.

• Power & cooling demand: High RPM drives plus multiple modules require good cooling and clean power.

• Firmware & compatibility: Using non-certified drives can cause instability.

• Cost vs SSD: In many cases, SSDs or NVMe will outperform, although at higher cost.

• Expansion complexity: If you scale far, managing tiers, migrations, and interconnects may require careful design.

Best Practices for Deploying Dell SCV2020 5H3XX with 5H3XX

Drive Selection & Firmware

• Use Dell-certified drives with supported firmware for that SC series.

• Before inserting new drives, ensure firmware revision matches or is compatible with existing drives.

• Maintain a consistent drive type in a performance tier to avoid unpredictable behavior.

Cooling & Power Design

• Mount in a rack with proper airflow front-to-back.

• Provide redundant power circuits if possible.

• Monitor temperature and ensure fans are functioning within spec.

RAID / Tiering Strategy

• Leverage hybrid tiers: let faster drives or SSDs act as a cache or hot tier; use 5H3XX drives for general pool.

• Use redundancy (e.g. RAID 6 or RAID 10 depending on tradeoffs) so one drive failure doesn’t degrade service critically.

• Plan capacity headroom — always leave some spare drives or blank slots for growth.

Monitoring, Alerts & Maintenance

• Use Dell Storage Manager / SupportAssist to monitor drive health, temperature, and alerts.

• Replace drives preemptively if SMART / system flags warn of failure.

• Schedule maintenance windows for firmware updates (controllers, drives, backplane) with minimal disruption.

Testing & Validation

• Before full deployment, use synthetic workloads to validate IOPS / throughput and confirm no bottlenecks (controller, interface).

• Validate data integrity after drive replacements or array reconfigurations.

• Test failover scenarios (remove one controller, one drive) to ensure redundancy works correctly.

Alternative Options & When to Choose Other Solutions

While an SCv2020 + 5H3XX setup can be strong, you should consider alternatives depending on your needs:

• All-SSD / NVMe arrays: For ultra-low latency or high IOPS, SSDs or NVMe are better.

• Larger arrays / scale-out systems: If your storage needs grow significantly, you may need SAN / scale-out storage systems.

• Use of newer Dell SC / PowerStore / Unity lines: Dell often refreshes its storage product lines; newer systems may offer better efficiency or features.

• Cloud storage / hybrid cloud architectures: For elastic scaling, offload infrequently used data to cloud or integrate cloud tiers.

The SCv2020 + 5H3XX configuration fits a middle ground: high reliability, good performance, at controlled cost.

Example Deployment Scenario & Thought Process

Imagine a mid-size company running a virtualization infrastructure:

1. They install an SCv2020 chassis in their data center rack.

2. Populate 16 slots with 5H3XX drives (1.8 TB, 10K SAS) in the performance tier.

3. Add a few SSDs or faster SAS as a hot tier.

4. Use RAID 10 for critical VM volumes, RAID 6 for file shares.

5. Connect front-end via dual Fibre Channel or iSCSI to redundancy in servers.

6. Monitor and replace failing 5H3XX drives automatically without downtime, thanks to hot-swap and redundancy.

This setup provides consistent performance for VMs, file services, applications, with room to expand.

Future Relevance & Lifecycle Considerations

Given the pace of storage tech, how futureproof is SCv2020 + 5H3XX?

• The mechanical drive (5H3XX) will gradually lag behind SSD/NVMe in performance, so its best use will likely shift to capacity or cold data tiers.

• Dell’s newer storage platforms may phase out older SCv series support over many years; plan migrations.

• Firmware updates will eventually cease; keep spares and plan replacement timelines.

• As workloads evolve (AI, real-time analytics), higher IOPS demands may pressure this combination.

Thus, even though SCv2020 + 5H3XX remains viable now, planning for eventual upgrade or migration is prudent.

Conclusion

• Dell SCV2020 5H3XX is a compact, modular enterprise storage system able to host up to 24 SAS drives, with redundant controllers and multiple connectivity options.

• 5H3XX is a Dell-certified enterprise 1.8 TB, 10,000 RPM, 12 Gb/s SAS drive used in SC / Compellent arrays.

• Together, they form a balanced mid-tier enterprise storage solution, offering performance, reliability, and expansion potential.

• Success depends on using compatible firmware, proper cooling, redundancy, and monitoring.

• Over time, mechanical drives may shift to capacity roles, and platform lifecycle should be managed.
