Unity D4-D2SFXL2-7680 7.68TB 2.5″ SAS 12Gbps SSD for Dell Unity XT Premium Storage

Keywords

Unity D4-D2SFXL2-7680, 7.68TB SAS SSD, 12Gbps interface, Dell Unity XT drive, SFF 2.5-inch drive, high capacity enterprise SSD, SAS 12G / SAS-520, refurbished Unity SSD

Description

The Unity D4-D2SFXL2-7680 is a Dell EMC Unity XT 2.5-inch SFF SSD with **7.68 TB** capacity, using SAS 12 Gbps interface. It is designed as a high-capacity enterprise drive suitable for Unity XT storage systems, offering strong performance for demanding storage workloads. Sources note the capacity, form factor and interface specifically for Unity XT or Unity storage environments.

This drive is often sold refurbished or remanufactured (RI or “Remanufactured / Refurbished Internal” condition), which makes it a cost-efficient way to expand capacity in your Unity XT array without paying new-drive prices. Warranty & testing vary by vendor.

Its SFF 2.5-inch size allows it to fit into Unity XT enclosures and drive trays (Gen-14 or equivalent trays) with front hot-plug capability. Unity XT and compatible DAEs support this drive with 12 Gbps SAS back-end.

Performance is optimized for read-intensive or mixed workloads; SS-SAS SSDs like this one (if labelled “RI”) generally prioritize endurance and read performance over write throughput, making them excellent for workload caching, metadata, or “hot” tier storage.

Capacity-wise, upgrading with these 7.68TB SSDs enables significant scale-up in Unity XT pools, especially when replacing older smaller SSDs or spinning disks. Since they match form factor and interface, integration is relatively simple, lowering complexity in upgrades.

Compatibility

The D4-D2SFXL2-7680 is compatible with a range of Dell EMC Unity XT storage arrays and associated expansion enclosures that support 2.5-inch SAS 12 Gbps SSDs and Unity’s drive firmware/hardware requirement. Vendors listing compatibility include Unity XT 380/F, 480/F, 680/F, 880/F, etc.

Trays / sleds must support 2.5-inch SSDs (Gen-14 or equivalent) and the drive back-end must provide 12 Gbps SAS connectivity. The drive firmware version must be Unity compatible to ensure monitoring, health reporting, SMART attributes, and array operations function correctly. Refurbished drives should be verified for this.

Since it's an SSD, latency and throughput will be much better than spinning disks. However, for write-heavy workloads, endurance ratings matter—vendors should supply specs (DWPD, write endurance) if write intensity is high. Using these drives in pools with mixed drive types can impact performance predictability.

Usage Scenarios

1) Capacity Expansion in Unity XT Arrays: Perfect for replacing older drives or adding new drives to increase usable capacity in Unity XT storage pools with high throughput demands.

2) Hot / Performance Tier SSD Pools: For workloads needing low latency and high IOPS (e.g. hyperconverged, virtualization, database metadata, caching), using this SSD will improve response times significantly.

3) Read-Intensive Workloads: Because many vendors list these as “RI” (read-intensive) units, they are well suited for workloads dominated by reads, like analytics, log servers, content delivery, etc.

4) Boot / OS / Metadata Drives: Can be used in Unity XT for system metadata, small LUNs, or boot partitions where speed matters.

5) Mixed SSD / HDD Hybrid Environments: Unity XT supports tiering; using these high-performance SSDs in “hot tier” alongside larger but slower SAS/SATA drives for capacity provides both performance and cost efficiency.

Frequently Asked Questions

Q: What does “RI” on some listings mean for this SSD, and will it limit usage?
A: “RI” stands for Read-Intensive. SSDs with this classification are optimized for workloads where reads dominate, not heavy sustained writes. For many metadata, read cache, or file system access workloads, this is fine; for write-heavy workloads (e.g. large transactional databases, logging) you may wish to consider SSDs with higher write endurance.
Q: Will this drive work in Unity XT without firmware or compatibility issues?
A: Yes—so long as the drive’s firmware matches or is supported by Unity XT, and the tray/backplane accepts the SAS 12 Gbps interface. Refurbished or third-party drives should be validated and tested, and often vendors supply drives with Unity certified firmware.
Q: How much performance improvement can be expected compared to spinning SAS HDDs?
A: Huge improvements: lower latency, higher IOPS, more consistent performance under load. Particularly for random I/O, small block access, and mixed workload environments. SSDs tend to reduce latency by order of magnitude and improve throughput several-fold compared to typical 10K/15K HDDs. Actual gain depends on configuration and RAID/tiering.
Q: Are there special power, cooling or drive bay requirements for this SSD?
A: Since it's a 2.5-inch SFF SSD, power and physical bay are standard in Unity XT and similar arrays. But ensure airflow is sufficient, temperature monitoring is working, and power supply capacity is enough, especially in highly dense SSD-loaded enclosures. Enterprise SSDs generate more heat under sustained workload than HDDs.
