The PERC H750 RAID Controller Card from Dell offers reliability and performance in addition to providing management with the tolerant disk subsystem failures. This RAID controller Card offers expandable 8 GB storage capacity to improve the performance of your server systems.
The double module channel provides high-speed connectivity. This product has been tested and validated on Dell systems to ensure compatibility with your computer. It is supported by Dell Technical Support when used with a Dell system.
These cards are high-performance, 11th-generation controller typically found in Dell’s 14th and 15th-generation PowerEdge servers (like the R640, R740, R650, and R750).
Special features of these RAID cards:-
- ::The 8GB Cache: This is the standout feature. Most standard RAID cards have 1GB or 2GB of cache. With 8GB, this card can "buffer" massive amounts of incoming data, making your server feel much faster during heavy write operations.
- ::RAID 6 Support: Unlike entry-level cards (like the H330/H350), this supports RAID 6, which allows two hard drives to fail simultaneously without losing any data.
- ::PCIe 4.0: It is designed for newer servers that support faster bus speeds, ensuring the controller itself doesn't become a bottleneck for fast SSDs.
-
You should use the HYM6Y/H750 if you are running:
- ::Heavy Virtualization (VMware ESXi, Proxmox, Hyper-V).
- ::High-Traffic Databases (SQL, Oracle).
- ::Enterprise Storage where data safety (RAID 6) is a priority.
-
Here is what makes the HYM6Y/H750 unique compared to standard RAID cards:
1. Massive 8GB NV Cache
The most "special" feature of this card is its 8GB non-volatile (NV) cache.
- ::The Benefit: Most RAID controllers have 1GB or 2GB. 8GB allows the server to handle massive "bursts" of data without slowing down.
- ::Flash-Backed: It uses a flash-backed cache (Zero-Maintenance Cache Protection), meaning if the server loses power, the data in the cache is written to flash memory. You don't have to replace a CMOS battery every two years.
2. PCIe Gen 4.0 Support
The HYM6Y is one of the first generations to utilize PCIe 4.0.
- ::This doubles the bandwidth between the controller and the motherboard compared to older PCIe 3.0 cards (like the H730P).
- ::It is essential if you are using high-speed 12Gb/s SAS SSDs, as it prevents the bus interface from becoming a bottleneck.
3. "Hardware Root of Trust" Security
Unlike older cards, the H750 series includes advanced security features:
- ::Secure Boot: The card only runs Dell-signed firmware, preventing "rootkit" attacks at the storage controller level.
- ::Self-Encrypting Drive (SED) Management: It has dedicated hardware to manage encrypted drives without a performance penalty.
4. Broadcom SAS3916 Chipset
Under the hood, this card uses the Broadcom SAS3916 RAID-on-Chip (ROC). This processor is significantly more powerful than the ones found in the H330 or H350, allowing it to handle complex RAID calculations (like RAID 6 or 60) with virtually zero impact on the server’s main CPU.
