HPE 835565-B21 340GB SATA 6G Read Intensive-2 Dual M.2 Kit

HPE 835565-B21 340GB SATA 6G Read Intensive-2 Dual M.2 Kit

Brand:

HPE

The HPE 835565-B21 is a dual 340GB SATA 6G Read Intensive-2 M.2 kit for supported HPE ProLiant ML/DL server configurations. It combines two M.2 SSDs with a read-focused workload profile, providing compact server-local storage for operating systems, boot environments and read-intensive applications. With SATA 6Gbps connectivity and a 3-year warranty, it is positioned as the dual-drive option alongside HPE's single-drive 835563-B21.

OVERVIEW

The HPE 835565-B21 is a dual 340GB SATA 6G Read Intensive-2 M.2 kit for supported ProLiant ML/DL servers. Compatibility: HPE documents M.2 support through the B140i SATA controller in applicable configurations. Compared with single-drive 835563-B21, this SKU provides two 340GB M.2 SSDs and supports software RAID configurations where the server permits them. It is a compact choice for read-focused server storage.

USE CASES

Server operating-system storage
The dual M.2 configuration provides compact local storage for supported server boot and operating-system deployments.
Read-intensive application workloads
The Read Intensive-2 classification makes the kit appropriate for workloads where data reads are more prominent than sustained heavy writes.
Software RAID deployments
In supported configurations, the dual-drive design can be used for software RAID, providing infrastructure teams with additional storage-layout flexibility.
HPE ProLiant boot infrastructure
M.2 storage helps reserve conventional drive bays for other storage requirements while providing dedicated local server storage.
Compact server storage upgrades
The M.2 form factor provides a space-efficient way to add SSD capacity to compatible ProLiant configurations.
Virtualization host storage
Can be considered for supported virtualization deployments where local, read-focused SSD storage is required for boot or selected workloads.
Server refresh projects
Provides a defined HPE option part number for organizations standardizing supported ProLiant storage configurations.
Dual-drive storage configurations
Two M.2 SSDs give administrators more configuration flexibility than HPE's corresponding single-drive 340GB kit.
