4XB7B03838 is a Lenovo ThinkSystem DE Series 24TB 7.2K 3.5-inch HDD 2U12 option, feature code C7XS, for qualified DE array and shelf configurations.
This is a storage-array procurement page. Do not treat 4XB7B03838 as a ThinkSystem server HDD just because the capacity and connector class look familiar.
Buy 4XB7B03838 only for DE Series 2U12 LFF array paths that list the option. A DE Series qualified drive should not be assumed interchangeable with a ThinkSystem server HDD.
Verify the part number, carrier, firmware, sector format and server or storage-array qualification before ordering. A bare mechanism or third-party compatible listing can be useful, but it is an alternative unless it is sold as the qualified OEM kit or spare you need.
These are the verified procurement identifiers and configuration constraints that should survive from quote to purchase order.

No exact in-stock live row is currently matched for 4XB7B03838. If no alternatives render, the model should be treated as unavailable in the tracked live catalogue.

Nothing in this tier is in stock right now. That is a stock statement, not a catalogue gap — see every channel we track.
This table is computed from live DatacenterDisk rows when an exact in-stock match exists. It is intentionally blank for unavailable models rather than filled with stale prices.
| Live model | Drive price | $/TB | 1 drive | 4 drives | 8 drives | 12 drives |

| No exact in-stock row is available right now. Use the availability table for nearby live alternatives, then re-check the exact model before ordering. | ||||||
These are procurement paths to evaluate when exact stock is absent. Alternatives still require the exact platform, controller, sector format, carrier and support policy to approve them.
| Alternative | When it can work | Procurement warning |
|---|---|---|
| 4XB7B03838 | Best replacement path for the DE Series non-SED 24TB 2U12 drive option. | Do not substitute a ThinkSystem server drive. |
| 4XB7B13111 | Alternative only when the DE array is configured for the SED option and key-management requirements are satisfied. | Do not mix SED and non-SED behavior casually inside array drive groups. |
| Another DE-listed NL-SAS HDD option | Possible when Lenovo's DE option matrix lists it for the exact array, shelf and firmware. | Capacity-only matches are not enough. |
| Generic 24TB NL-SAS HDD | Only if Lenovo support explicitly accepts the non-OEM drive for the array. | No DE Series carrier, firmware or array qualification by default. |
Use this table before accepting a quote, especially when new, open-box, refurbished and bare-drive listings appear side by side.
| Check | Why it matters |
|---|---|
| Exact option | 4XB7B03838 must appear on the quote or listing when you need the exact OEM option. |
| Carrier | DE Series 2U12 array carrier |
| Firmware path | OEM-qualified firmware can decide update eligibility, health reporting and support handling. |
| Sector format | Array-qualified sector format; verify against the exact DE firmware and shelf option matrix must match the controller, array and existing drive group. |
| Condition | New, open-box, refurbished and used units should be compared as different offers, not as the same price point. |
| Support | Handled through Lenovo DE array or option support terms |
Raw decimal capacity is shown before filesystem formatting, RAID, hot spares, snapshots or vendor overhead.

DE Series arrays are systems made of controllers, shelves, drives, firmware and management software. A drive that is fine in a server can be the wrong purchase for an array if it is not on the DE option matrix.
For expansion, match the exact shelf type and supported drive count. Lenovo Press lists the 2U12 option with a maximum quantity of 12 in the relevant enclosure. For replacement, match the existing drive group and array firmware requirements.
4XB7B03838 is the non-SED 24TB 2U12 option in the cited Lenovo DE table. If the array is using encrypted drives or an encryption policy, evaluate 4XB7B13111 instead and check key-management requirements.
No. It is a ThinkSystem DE Series storage-array HDD option for qualified DE paths.
No. The cited Lenovo table lists it as the non-SED 24TB DE Series HDD; 4XB7B13111 is the SED option.
The current DE2000H Lenovo Press table groups these 24TB options under 3.5-inch 12Gb NL-SAS hot-swap HDDs.
