Description

Revolutionize your data center's storage capacity with the dell powervault me5284, a massive 5U high-density storage array designed to handle the world's most data-intensive workloads. Unlike standard enterprise servers that rely on limited internal drive bays, this purpose-built SAN (Storage Area Network) enclosure offers an astonishing 84 drive slots. Whether you are building a private cloud storage server or deploying a centralized backup repository, the ME5284 provides the physical density and logical performance required by modern IT environments.

This specific configuration is a true 840tb storage powerhouse, arriving half-populated with 42 pieces of 20TB 7.2K SAS HDDs. These enterprise-class 12Gbps drives feature ISE (Instant Secure Erase) technology, allowing administrators to cryptographically wipe data in seconds when retiring or repurposing drives. By populating only 42 of the 84 available slots, this system grants your organization immediate petabyte-scale capacity while leaving a massive 50% physical overhead for future expansion as your data footprint inevitably grows.

Data routing and I/O performance are managed by state-of-the-art Dual Controllers, featuring an 8-Port 25gb iscsi san interface. This dual active-active controller architecture ensures that your dell servers never experience a single point of failure. To guarantee seamless deployment into your existing network fabric, the package includes four 25GbE SFP28 SR Optics and two 10GbE Copper Twinax Direct Attach Cables (DAC). This ensures you have the immediate physical connectivity required to link the storage array to your core switches or directly to your dell poweredge server hosts.

Enterprise reliability is the cornerstone of this build. It is fortified with dual redundant 2200W power supplies operating at 220-240Vac, complete with heavy-duty C19-C20 power cords. Furthermore, when you buy server hardware of this caliber, peace of mind is paramount. This unit includes a 36-month Dell ProSupport contract with Onsite Service, ensuring that expert Dell technicians are available to resolve any hardware anomalies rapidly, minimizing downtime and protecting your critical server storage assets.

Key Features

  • Extreme Storage Density: 5U rackmount chassis capable of holding up to 84x 3.5-inch hard drives.
  • Massive Included Capacity: Pre-installed with 42x 20TB SAS HDDs, delivering 840TB of raw storage space.
  • High-Throughput Controllers: Dual active-active controllers with 8x 25Gb iSCSI ports for exceptional bandwidth.
  • Included Networking Optics: Comes with 4x 25GbE SFP28 SR optics and 2x 10GbE 3-meter DAC cables for immediate fabric integration.
  • Enterprise Data Security: Drives feature Instant Secure Erase (ISE) for safe and rapid drive decommissioning.
  • High Availability Power: Dual 2200W redundant hot-plug power supplies ensure continuous operation.
  • Premium Support: Backed by a 3-Year Dell ProSupport contract featuring Onsite Service.

Compatibility

The dell powervault me5284 is engineered for universal server storage compatibility across modern data centers. It integrates seamlessly with the entire portfolio of dell servers, particularly 14th, 15th, and 16th generation models. The 25gb iscsi san backend is fully certified for top-tier virtualization hypervisors, including VMware vSphere (ESXi), Microsoft Hyper-V, and Citrix XenServer. The inclusion of both 25GbE optics and 10GbE DAC cables allows for flexible auto-negotiation, ensuring the array can connect to both legacy 10Gb standard networks and modern 25Gb high-speed ethernet fabrics.

Usage Scenarios

This configuration acts as an unparalleled **Video Surveillance and CCTV Archive**. Security environments generating thousands of hours of high-definition video require deep, reliable storage. With 840TB of raw capacity and the ability to expand further, this array can hold years of retention data. The 25Gb iSCSI throughput ensures that hundreds of camera feeds can be written to the disks simultaneously without frame dropping or latency.

It is also highly recommended as a **Centralized Backup and Disaster Recovery Target**. When paired with enterprise backup software like Veeam, Commvault, or Dell NetWorker, the ME5284 serves as a robust cloud storage server repository. The massive capacity allows for frequent synthetic full backups, while the Instant Secure Erase (ISE) drives ensure compliance with strict data destruction regulations if drives are retired.

For research institutions and financial sectors, this array supports **High-Performance Computing (HPC) and Big Data Analytics**. As enterprise servers crunch massive datasets—such as genomic sequencing or market backtesting—they require a backend storage system that can deliver huge sequential read/write payloads. The dual-controller architecture prevents bottlenecking during intense computational runs.

Finally, it is the perfect shared storage backend for a **Dense Virtual Desktop Infrastructure (VDI)**. When connecting a cluster of dell poweredge server nodes via the 10GbE or 25GbE iSCSI network, this SAN provides the shared datastore necessary for High Availability (HA) and live migration (vMotion) of hundreds of virtual employee workstations, ensuring business continuity.

Frequently Asked Questions

Q: Can I expand the storage capacity of this array later? A: Absolutely. The ME5284 chassis holds up to 84 drives, and this configuration includes 42 drives. You have 42 empty bays remaining, allowing you to double your storage capacity in the future simply by purchasing and sliding in compatible Dell 20TB SAS HDDs.

Q: What does the "ISE" designation mean on the hard drives? A: ISE stands for Instant Secure Erase. These drives contain hardware-level encryption. When an administrator issues an ISE command, the drive deletes its internal cryptographic key, rendering all 20TB of data instantly permanently unreadable. This saves days of software wiping when repurposing or discarding drives.

Q: Will this storage array run on standard 110V office power? A: No. Due to the extreme density and the power required to spin up 84 mechanical hard drives, the ME5284 is equipped with 2200W power supplies that require high-voltage input (220-240Vac). You must ensure your datacenter rack PDUs support C19/C20 connections at 220V+.

Q: How do I connect the included 10GbE DAC cables to my servers? A: The included 10GbE SFP+ to SFP+ Direct Attach Cables (DACs) are designed to plug directly from the iSCSI controller ports on the ME5284 into compatible SFP+ network interface cards (NICs) on your host servers, or into an intervening 10Gb/25Gb Ethernet switch for a wider SAN fabric.
