Description

Scale your data center infrastructure effortlessly with the Dell PowerVault ME484 Expansion Enclosure. Designed to meet the ever-growing demands of enterprise data generation, this 5U high-density JBOD (Just a Bunch Of Disks) provides an unparalleled capacity boost to your existing dell server or PowerVault SAN environments. By leveraging a dedicated expansion chassis rather than investing in entirely new head units, organizations can significantly reduce capital expenditure while rapidly deploying petabyte-scale environments.

This specific configuration is a high density storage behemoth. It comes pre-populated with 30 pieces of massive 24TB 7.2K 12G SAS hard drives. Out of the box, this delivers a staggering 720TB of raw storage capacity. Because the ME484 chassis holds up to 84 drives in total, populating it with 30 drives provides massive immediate capacity while leaving an incredible 54 drive bays completely empty and ready for future expansion as your server storage requirements inevitably multiply.

To ensure maximum uptime and data availability, this array features Dual 12G SAS Expansion Modules (Controllers). This active-active multipath architecture guarantees that data flows continuously to your connected enterprise servers, eliminating single points of failure. The redundant controller design is complemented by Dual Hot-Plug Power Supplies, ensuring that your storage remains online even during power circuit failures or routine maintenance operations.

When IT departments look to buy server hardware, maximizing ROI is always the top priority. The ME484 serves as a highly economical path to hyper-scale. Instead of replacing aging infrastructure, adding this expansion transforms your existing setup into a massive cloud storage server. It operates effectively as a cheap server expansion alternative compared to buying premium primary arrays, delivering the tier-3 or backup storage capacity necessary to keep your business fully compliant and your data secure.

Key Features

  • Immense Raw Capacity: Pre-installed with 30x 24TB SAS HDDs, offering 720TB of immediate storage.
  • Extreme Scalability: 5U chassis supports up to 84 drives, leaving 54 bays open for future upgrades.
  • High-Availability Architecture: Dual 12G SAS expansion controllers provide active-active multipathing.
  • Enterprise Drive Endurance: 12Gbps 7.2K RPM SAS drives ensure reliable 24/7 continuous operation.
  • Fault-Tolerant Power: Dual redundant hot-plug power supplies protect against unexpected downtime.
  • Seamless Integration: Designed to daisy-chain with Dell PowerVault ME4 and ME5 series arrays.
  • Mounting Hardware: Includes a heavy-duty rack kit for standard 19-inch data center racks.

Compatibility

The Dell PowerVault ME484 Expansion Enclosure is highly versatile. It is primarily designed to daisy-chain directly into Dell PowerVault ME4 series (ME4012, ME4024, ME4084) and ME5 series (ME5012, ME5024, ME5084) base arrays to instantly add capacity to your existing SAN. Furthermore, it is fully supported as a Direct Attach Storage (DAS) JBOD. Using external Mini-SAS HD cables (SFF-8644), you can connect the ME484 directly to a compatible 12Gb SAS Host Bus Adapter (HBA), such as the Dell HBA355e, installed in the PCIe slots of standard dell servers like the PowerEdge R750 or R760.

Usage Scenarios

This 720TB configuration is the perfect hardware backend for a Centralized Backup and Disaster Recovery Repository. By attaching this massive enclosure to your backup dell server running Veeam, Commvault, or Dell NetWorker, you create an ultra-deep repository for synthetic full backups, immutable storage retention, and long-term archiving, ensuring compliance with rigorous enterprise data policies.

It also excels in the Media and Entertainment (M&E) sector as a vast digital asset library. Video production studios dealing with uncompressed 4K and 8K footage require high density storage that can scale rapidly. The ME484 allows studios to keep entire seasons of raw footage online and accessible via their enterprise servers without having to rely on slow, offline tape storage.

For organizations deploying a Private Cloud or Software-Defined Storage (SDS), this enclosure acts as a perfect high-capacity block. By using an HBA to pass these drives directly to an OS like Windows Server (Storage Spaces) or a Linux-based ZFS array, you can build a massive, customized cloud storage server tailored to your specific file-sharing or data-lake needs.

Frequently Asked Questions

Q: Is the Dell ME484 a standalone SAN array that connects directly to my network switch?
A: No, the ME484 is a JBOD (Just a Bunch Of Disks) expansion enclosure. It does not have internal RAID controllers with iSCSI or Fibre Channel ports. It must be connected via SAS cables to a primary Dell PowerVault head unit (like the ME5084) or directly to a Host Bus Adapter (HBA) installed inside a host server.

Q: Since this holds 30 drives, can I add more drives later?
A: Absolutely. The ME484 chassis is built to hold up to 84 drives in its dense 5U drawers. With 30 drives installed, you have 54 empty drive slots available. You can purchase additional Dell 3.5" SAS HDDs and add them to the enclosure as your capacity needs grow.

Q: What type of cables do I need to connect this expansion to my existing server or SAN?
A: You will need external 12Gb SAS cables, specifically those with Mini-SAS HD (SFF-8644) connectors. You will connect these from the "OUT" ports on your primary SAN controller (or server HBA) to the "IN" ports on the ME484's dual controllers.
