CacheCade Technology

The Dell WXXHY PERC H965i supports CacheCade technology, which allows SSDs to be used as an extended cache for even faster performance. This feature significantly boosts read-intensive workloads and improves overall system responsiveness.

RAID Levels Supported

One of the standout features of the Dell WXXHY PERC H965i is its support for multiple RAID levels, offering flexibility and reliability for various storage configurations. These include:

RAID 0 – Striping

RAID 0 offers improved performance by splitting data across multiple drives. It is ideal for applications that require high-speed access, but it does not provide redundancy.

RAID 1 – Mirroring

RAID 1 ensures data redundancy by duplicating data across two drives. This setup is perfect for critical systems that prioritize data integrity over performance.

RAID 5 – Striping with Parity

RAID 5 balances performance and data protection by distributing parity information across all drives in the array. It is a popular choice for general-purpose storage.

RAID 6 – Dual Parity

RAID 6 provides extra redundancy by storing parity information on two drives. This configuration offers enhanced protection against data loss, even in the event of multiple drive failures.

RAID 10 – Striping and Mirroring

RAID 10 combines the benefits of RAID 0 and RAID 1, offering both high performance and redundancy. It is ideal for mission-critical applications.

Data Protection and Reliability
