DELL PERC RAID & TRI-MODE HBA
Dell PowerEdge PERC RAID Controllers & HBA Adapters
Genuine Dell PowerEdge RAID Controller (PERC) hardware RAID cards and Host Bus Adapters for PowerEdge servers — PERC H965/H975 with flash-backed cache and HBA465 tri-mode SAS/SATA/NVMe, internal and external form factors.
Choosing the right storage controller determines whether your drives run in protected hardware RAID or are passed straight to the operating system. We supply the exact Dell PERC or HBA for your chassis slot — front/DC-MHS or full-height adapter — verified against your service tag so it seats correctly and supports the drives you plan to run.
Controllers we supply
PERC H965i (internal)
Flagship internal RAID card, PCIe Gen4, 16 lanes 2×8, 8GB flash-backed DDR4 cache, RAID 0/1/5/6/10/50/60; up to 16 SAS/SATA and 8 NVMe directly.
PERC H965e (external)
External 4×4 RAID adapter for connecting PowerVault JBODs, supporting up to 240 SAS drives across enclosures with the same 8GB cache.
PERC H975 series
Newer PERC generation for current platforms; ask for the H975 revision qualified by your specific server.
PERC H365 (entry)
Entry hardware RAID without the large cache, suited to basic RAID 0/1/5/10 protection on value configurations.
HBA465i (internal)
Tri-mode 16-port 2×8 HBA with no cache, passes SAS/SATA/NVMe drives directly to the OS for software-defined storage.
HBA465e (external)
External tri-mode HBA for attaching enclosures in IT/non-RAID mode, popular with ZFS, Ceph and software RAID stacks.
Typical applications
- Hardware RAID protection for virtualization hosts
- Connecting external PowerVault JBOD shelves
- JBOD/passthrough for ZFS, Ceph and software RAID
- Replacing a failed or under-featured PERC card

Frequently asked questions
What is the difference between a PERC and an HBA?
A PERC is a hardware RAID controller with on-card cache that manages redundant arrays, while an HBA passes drives straight through to the OS with no RAID logic, used for software-defined storage.
Which PERC controller fits my PowerEdge?
Current platforms use PERC H965/H975 in internal front/DC-MHS or adapter form, and H965e externally. Send your service tag and we confirm the exact supported card and slot.
What does the PERC 8GB flash-backed cache do?
The cache accelerates writes while a flash-backed module protects data in cache during a power loss, reducing corruption risk and improving performance over cacheless entry cards.
Can a PERC manage NVMe drives?
Yes. The H965 supports Gen3/Gen4 NVMe alongside SAS/SATA (up to 8 NVMe directly, more via a PCIe switch), so SAS/SATA and NVMe can be managed from the one controller where the platform allows.
When should I choose an HBA465 instead of a PERC?
Choose the HBA465 when your OS or hypervisor handles RAID and data services itself, such as ZFS, Ceph, Storage Spaces Direct or vSAN, which prefer direct, unfiltered disk access.
What RAID levels does the PERC H965 support?
The H965 supports RAID 0, 1, 5, 6, 10, 50 and 60. We can configure the level and virtual-disk layout you need and verify it before a server ships.
What is the external PERC H965e used for?
The H965e connects external PowerVault JBODs and supports up to 240 SAS drives across enclosures, giving a single server a large hardware-RAID storage footprint.
Do PERC cards support self-encrypting drives?
Yes. PERC controllers support local and iDRAC key management and host-managed SED/ISE drives, so encryption can be coordinated through iDRAC on supported configurations.
Is the entry PERC H365 sufficient?
H365 provides basic hardware RAID without the 8GB cache, suited to light or non-performance arrays. For production databases or heavy writes we recommend H965.
Can you install and configure the controller with a server order?
Yes. We fit the PERC or HBA, create the RAID or pass-through layout you request, update firmware and verify the subsystem before shipping the complete build.
Are front/DC-MHS and full-height adapter cards interchangeable?
Often no. The form factor depends on the chassis slot and backplane. We select front/DC-MHS versus adapter based on your exact model to avoid seating or cable conflicts.
What happens if I fit an unsupported controller?
The system may not POST the card, fail to recognize drives or block certain features. Genuine Dell-qualified controllers matched to your platform avoid these failures.
How do I identify my current PERC model?
Read the card label in iDRAC/System Setup (e.g. PERC H755/H965) or send us your service tag; we identify the installed controller and a compatible replacement or upgrade.
What warranty covers a Dell PERC or HBA?
New genuine controllers carry the manufacturer warranty. We confirm the term and coordinate replacement handling if a defect occurs.
