Define the drive and the workload
Enterprise NVMe sourcing should keep form factor, interface, capacity, endurance or workload need, firmware, carrier, platform, and condition together.
Information needed for quotation
| Area | Buyer input |
|---|---|
| Platform | Server or storage system, bay, carrier, and firmware context |
| Drive | Form factor, interface, capacity, and exact manufacturer or OEM reference |
| Use | Workload or endurance requirement and replacement constraints |
| Supply | Condition, quantity, health or traceability evidence, and target delivery |
Condition and firmware are explicit
Do not infer condition, remaining life, firmware compatibility, or carrier inclusion from a family description. State which evidence and included parts must appear in the quotation.
Technical parameters and selection boundaries
Published configurations differ by manufacturer and exact part number. These are selection dimensions, not one combined specification.
| Parameter | Documented example or choice | Verify for this request |
|---|---|---|
| Interface and management | The inspected D7-P5520 / D7-P5620 brief specifies PCIe 4.0 x4, NVMe 1.4 and NVMe-MI 1.1. | Confirm the server backplane, lane wiring and firmware support. A matching drive outline is not an interface qualification. |
| Form factor and thickness | D7-P5520 examples include U.2 15 mm, E1.S 9.5 mm / 15 mm and E1.L 9.5 mm. | These are distinct mechanical choices. Match the bay, connector, carrier, airflow and drive thickness to the platform. |
| Capacity by construction | In the inspected brief: P5520 U.2 lists 1.92 / 3.84 / 7.68 / 15.36 TB; E1.S lists 1.92 / 3.84 / 7.68 TB; E1.L lists 15.36 TB. | Historical brief coverage, not a complete current ordering matrix. Obtain the current exact SKU for the requested form factor and capacity. |
| Published performance ceilings | P5520 series brief: up to 1.1 million / 220,000 4 KB random read/write IOPS and up to 7,100 / 4,200 MB/s 128 KB sequential read/write. | Series maxima, not a guarantee for every capacity or one simultaneous workload. Require capacity-specific figures, queue depth, workload mix and steady-state test conditions. |
| Write endurance | The brief separates P5520 at up to 1 DWPD over five years from P5620 at up to 3 DWPD over five years. | Specify expected daily writes and workload before selecting a drive. A higher number belongs to the named series and cannot be assigned to P5520. |
| Device management | The brief lists NVMe-MI 1.1, PCIe VDM / MCTP and OCP cloud C0 log-page support. | Management features require compatible platform and software support; verify what the deployed firmware exposes. |
| Security scope | The current P5520 page lists AES-256 and TCG Opal 2.0; its FIPS 140-3 L2 statement is limited to U.2 15 mm capacities 1.92–15.36 TB. | Do not generalize certification to E1.S, E1.L or an unverified lot. If required, confirm the exact certificate, firmware and security-enabled SKU. |
Standard configurations and project options
| Configuration area | Documented option | Project decision |
|---|---|---|
| Capacity and physical build | Choose the documented capacity and form-factor combination before requesting a complete ordering code. | These are manufacturer product variants, not physical customization of a finished SSD. |
| Endurance class | Compare the standard-endurance P5520 and medium-endurance P5620 using the actual write workload. | Do not mix the endurance or random-write figures of the two series in a single specification. |
| Firmware and lifecycle documents | Request current firmware compatibility, PCN history and product-specific warranty terms. | Manufacturer support information does not establish this sourcing service as an authorized warranty channel. |
Representative models and configurations
Examples illustrate real product variation. A listed manufacturer or model is not a statement of our stock, authorization, or confirmed availability.
| Manufacturer / series | Published configuration | Important scope |
|---|---|---|
| Solidigm D7-P5520 — U.2 configuration | 3.84 TB; U.2; 15 mm; PCIe 4.0 x4 / NVMe 1.4. | Documented configuration example, not a complete order code. Current firmware, part number and server qualification must be confirmed. |
| Solidigm D7-P5520 — E1.S configuration | 7.68 TB; E1.S; 9.5 mm or 15 mm constructions listed separately. | Select the exact thickness; do not assume one carrier or thermal solution fits both. |
| Solidigm D7-P5620 — U.2 configuration | 3.2 TB; U.2; 15 mm; medium-endurance series. | Different series and capacity from P5520. Confirm the exact SKU and capacity-specific endurance before approving an alternative. |
Applications and procurement context
- For database, cloud and AI data-pipeline storage, start with I/O mix, expected daily writes, required capacity and the server bay. Compare candidate drives under the intended workload rather than headline throughput alone.
Compatibility, current supply, lead time, origin, and acceptance documents must be confirmed for the actual order.
