- HighPoint Rocket 7638D combines extreme GPU stream with massive SSD storage on only one PCIe slot
- Double MCIO ports and a CDFP interface Unlock Real Calculation Arrangement Fixing for HPC Works
- May host RTX 5090 and 16 Enterprise SSDs using a single compact expansion card
HighPoint Technologies is preparing to reveal Rocket 7638D on FMS2025, a single-castle PCIE GEN5 X16 addition card aimed at combining external GPU support and SSD storage with high capacity within a compact form factor.
This map is intended for use in environments where space restrictions are critical and both calculate and storage benefit are required.
HighPoint says Rocket 7638D supports the simultaneous use of a high-performance external GPU and up to 16 corporate class NVME SSDs, enabling consolidation of components that are typically spread over several slots.
Fusion of GPU -SUPPORT AND SSD CAPACITY IN A PCIE -SLOT
The design seems to be targeted at AI inference, high performance computing (HPC) and media production workload, where system density and thermal considerations could limit expansion options.
Rocket 7638D uses an external CDFP interface to accommodate a full-height, double or triple-castle Gen5 GPU supporting lengths up to 370 mm, including options such as NVIDIA GeForce RTX 5090 launched earlier this year.
Internally, the card is equipped with two MCIO ports that allow users to connect up to 16 NVME SSDs using either standard cabling or a back plan.
When paired with Kioxia LC9 SSDs, currently among the largest SSDs on the market of 245.66TB each, this setup can theoretically give up to 4PB for total storage.
While this configuration is likely to be limited by thermal problems, power and system compatibility constraints in some implementations, architecture enables high-density integration where such challenges can be addressed.
This is how you do
- Install Rocket 7638D in a PCIe Gen5 X16 Slot on a supported motherboard
- Connect a compatible Gen5 x16 GPU (eg RTX 5090) via the CDFP port
- Attach up to 16 NVME SSDs using double MCIO cables or through a Gen5-capable rear plan
- Ensure power supply and cooling are appropriate for both GPU and SSD load
- Use Firmwar Tools to control track distribution, power cycling and device surveillance
- Monitor System Status using LED indicators or Command Line Tools
In addition to 7638D, HighPoint shows its wider Rocket Series portfolio on FMS2025.
This includes Gen5 and Gen4 NVME -SWITCHES and RAID adapters capable of hosting up to 32 SSDs or 8 accelerators per day. Castle.
The RocketStor 6500 series, another part of this lineup, supports almost 1PB external storage from a single PCIe slot.
HighPoint’s infrastructure supports a number of NVME form factors including M.2, U.2/U.3, E1.S, E3.S and ESDFF.
It also includes features for real-time diagnostics, tuning at firmware level and integration with OEM platforms.
