HPE 838820-001 8GB Flash Media Kit

HPE 838820-001 8GB microSD Flash Media for ProLiant Servers

The HPE 838820-001 is an 8GB microSDHC flash card supplied as an HPE spare part. Rather than adding system memory, it gives a server a small, separate boot device that plugs into the internal microSD slot found on many ProLiant, Apollo and Synergy systems.

A card like this is most often used to boot an embedded hypervisor, so that every drive bay stays free for data. It is also handy as a quick replacement when an existing boot card fails or a host is being rebuilt.

You can order the 838820-001 from Euroland IT Store in New or Refurbished condition, depending on stock at the time.

Key Features At A Glance

• 8GB microSDHC card carrying an HPE spare number
• Fits the internal microSD slot on supported HPE servers
• Keeps hypervisor boot separate from your data drives
• No drive bay or controller port needed
• Also cross-referenced as 726118-002
• Offered New or Refurbished, subject to availability

What the 838820-001 Number Refers To

Unlike most items in our memory section, the 838820-001 is a storage card, not a DIMM. HPE labels it as an 8GB micro SDHC flash media card, and spares references list it alongside the number 726118-002 for the same 8GB card.

HPE also sells 8GB microSD media as a boxed retail option, the 726116-B21 Enterprise Mainstream Flash Media Kit. We have not been able to confirm from HPE records that 838820-001 is the official spare for that exact kit, so if your paperwork shows 726116-B21 please contact us and we will check the match for you.

The 838820-001 card also appears in listings for the HPE Dual 8GB microSD EM USB Kit (870891-001), which carries two cards so the boot device can be mirrored. If your server uses that dual kit, this card is a likely replacement for one of its two slots.

Using microSD as a Boot Device

A single microSD card is well suited to booting a lightweight operating system such as a hypervisor that loads into RAM and writes little back to the card. It is not intended for databases, heavy logging or general file storage. If a host writes logs or scratch data, point those to a disk or datastore instead, which also helps the card last longer.

Before swapping a card, copy any configuration you need. A new card is blank, so the operating system will have to be installed or restored onto it. Power the server down before opening the cover, as the internal slot is not designed for hot swap.

New HPE 838820-001 Card

The New option is an unused card, a sensible pick for a fresh hypervisor install. Its pricing and warranty appear as soon as you select it on this page.

Refurbished HPE 838820-001 Card

A Refurbished card has been used before and is offered at a lower price, which can suit test hosts or spares stock. Condition and warranty terms are shown when the option is selected, so please read them before ordering.

Is This the Right Card?

• Read the label on the existing card or its packaging for 838820-001 or 726118-002.
• Confirm your server has an internal microSD slot rather than a full size SD slot.
• Check whether the server uses a single card or a dual mirrored USB kit.
• Make sure 8GB is enough for the operating system you plan to boot.
