HPE NonStop NS8 X4 Overview
The HPE NonStop NS8 X4 is the high-end system of the NonStop X4 generation. It was introduced together with the entry-class NS4 X4. Both moved away from the blade design of earlier NonStop X systems: each NonStop CPU is now a rack-mounted HPE server.
This matters for parts. An NS8 X4 does not use the same CPU hardware as an NS7 X3, even though both run the NonStop OS L-series and many customers still call both systems "Tandem".
Component | NS8 X4 detail | Why it matters for parts |
System class | High-end x86 HPE NonStop, X4 generation | Parts must match the X4 generation, not older blade-based NonStop X systems |
NonStop CPUs | 2 to 16 per node, each a rack-mounted HPE server | Every CPU is a separate server with its own memory |
Processors | Intel Xeon Gold 6200 series (Cascade Lake) | Defines the memory generation (DDR4) |
Memory | Up to 256 GB per NonStop CPU, up to 4 TB per node | Memory is planned and upgraded per CPU |
System interconnect | InfiniBand HDR, 100 Gb/s, redundant X and Y fabrics | Adapters, cables and fabric switches are critical spares |
I/O controllers | Up to 56 V4 CLIMs (IP, Telco and Storage) | Networking and storage run through the CLIMs |
Storage CLIM | Based on HPE ProLiant DL380 Gen10, with 12G SAS and 16G Fibre Channel | SSDs and HDDs connect through the Storage CLIMs |
Operating system | HPE NonStop OS L-series, L20.10 or later | The RVU level can affect which hardware is supported |
Licensing | 2, 4 or 6 cores per CPU, optional NonStop Dynamic Capacity | Core licensing is separate from the hardware parts |
The NS8 X4 is a rack-server-based NonStop system, so the correct upgrade or replacement part always depends on the X4 generation, the component location and the HPE part number.

Storage expansion | Disk enclosures, SAS cables, Fibre Channel HBAs | Current enclosure count and storage layout |
Expansion and I/O | CLIM components, network adapters, InfiniBand adapters and cables | CLIM type and adapter part numbers |

Availability, condition and pricing are confirmed in every quote, so you know exactly what you are ordering before it ships.
SSDs and Storage Drives
In an NS8 X4, application data does not sit on drives inside the NonStop CPUs. Storage is handled by Storage CLIMs connected to SAS disk enclosures. Each enclosure holds up to 25 small form factor drives, and SSDs and HDDs can be combined in the same enclosure.
We supply SAS SSDs and HDDs for failed-drive replacement and for extra capacity. For the details on compatibility, firmware and carriers, see our guide to HPE NonStop NS8 X4 SSD upgrade options and compatibility.
Memory (RAM) for NonStop CPUs
The NS8 X4 uses Intel Xeon Gold 6200 series processors, which work with DDR4 memory. Each NonStop CPU supports up to 256 GB of RAM. Typical requests are replacement DIMMs after a memory error and upgrades to increase memory per CPU.
Memory must follow HPE's NonStop configuration rules, not only generic server rules. Our HPE NonStop NS8 X4 memory upgrade guide explains what to check.
Storage Expansion
When the existing enclosures are full, storage grows by adding drives, disk enclosures or Storage CLIMs. The NS8 X4 Storage CLIM offers 12G SAS for disk enclosures and 16G Fibre Channel, for example for SAN-attached HPE XP storage and tape. We can help with the matching enclosures, cables and HBAs.
Expansion: CLIMs, Networking and Interconnect
An NS8 X4 node supports up to 56 V4 CLIMs. IP and Telco CLIMs handle network traffic, while Storage CLIMs handle disks and tape. The system interconnect uses InfiniBand HDR at 100 Gb/s with two independent fabrics (X and Y), plus optional I/O expansion switches.
Typical expansion and spare parts in this area include network adapters, InfiniBand adapters and cables, and CLIM server components. Adding a new CLIM is a configuration change, so plan it together with your NonStop support team.
Replacement Hardware: Power, Cooling and Server Components
Many NS8 X4 components are based on HPE ProLiant Gen10 hardware, for example the DL380 Gen10 platform used for the Storage CLIM. This includes power supplies, fans, drive carriers, rails, PCIe adapters and cables. Some of these are shared with standard ProLiant servers, but always compare the exact HPE spare part number before ordering.
Replacement vs Upgrade on a Running NS8 X4
HPE NonStop systems are built so that a single component failure does not stop the business workload. That is why many NonStop parts orders are planned replacements, not emergencies. It still helps to separate two cases:
Like-for-like replacement: same HPE part number as the failed component. This is the lowest-risk option and the most common request.
Upgrade: more memory per CPU, larger or additional SSDs, more enclosures or more CLIMs. An upgrade changes the system configuration, so check the RVU level, HPE configuration rules and your service procedures first.
If you are not sure whether your request is a replacement or an upgrade, send us the details below and we will check it with you.
How to Identify the Correct HPE NonStop Part

FAQ: HPE NonStop NS8 X4 Parts
Where can I buy HPE NonStop NS8 X4 spare parts?
You can request a quote from server-parts.eu for NS8 X4 SSDs, memory, storage, expansion and replacement hardware. Send the HPE part number or a photo of the label for the fastest answer.
Are refurbished HPE NonStop parts available?
Yes. server-parts.eu supplies refurbished and used HPE NonStop / Tandem parts. Condition, testing and warranty terms are confirmed in the quote for each part.
Which NS8 X4 parts can be upgraded?
The most common upgrades are memory per NonStop CPU (up to 256 GB per CPU), SSDs and storage capacity, and I/O expansion through additional CLIMs. Each upgrade must follow HPE's NonStop configuration rules for your RVU.
Can I use NS7 X3 parts in an NS8 X4?
Not without checking. The NS7 X3 uses server blades, while the NS8 X4 uses rack-mounted servers as NonStop CPUs. Always compare HPE part numbers before reusing parts across generations.
Can I use any enterprise SSD in an HPE NonStop NS8 X4?
No. The NS8 X4 stores data on SAS drives behind the Storage CLIMs, and a replacement must match the HPE part number, carrier, firmware and supported capacity. A generic enterprise SSD is not a safe substitute. Our NS8 X4 SSD compatibility guide explains what to check.
Can older Tandem systems still be maintained?
Many HPE NonStop (Tandem) systems stay in production for years, supported by HPE or third-party maintenance providers. Refurbished spare parts help keep these systems running when new parts are no longer easy to get.
How do I identify the correct HPE part number?
Check the label on the component. Most HPE parts show a spare part number and often an option number. If you are not sure which number to use, send us a photo of the label.
Can server-parts.eu ship internationally?
Yes. server-parts.eu ships HPE NonStop parts worldwide. Delivery options and times are confirmed in the quote.
