Other Issues

1) Some of my hard drives show up during post and some don’t

Check on the following:

∙Are you using third party SCSI adapters? System memory limitations limit the number & size of option ROMs in the system. If you place too many adapters or adapters that take up too much space in memory, they may not install and show the hard drives connected to them.

∙If you disconnect your hard drives from the third party adapter and connect them to the on-board adapter, do they show up?

∙Verify that pin 1 on the data cable connects to pin 1 on the device. In most cases, if you orient the data cable so that the colored stripe on the cable is pointing towards the power connector on the device, you will have proper orientation.

∙Verify that the device power cable is firmly connected.

∙Have you properly terminated all your hard drives? If you are using Ultra 2 or Ultra 160 drives without a hot-swap backplane, place a terminator in the last connector on the SCSI cable. Ultra 2/Ultra 160 devices do not provide their own termination logic like Ultra Wide devic es did.

∙Check your SCSI ID numbers. SCSI devices must have their own unique ID on the SCSI bus. This number is set automatically when using an Intel SCSI hot-swap backplane, but must be set with jumpers on the device when using a SCSI cable. ID number should be set starting at 0 and must be set lower than 8 if booting from the drive.

If your hard drives still do not show, please fill out the included customer support form and call your customer support representative. Please pay special attention to the following information:

∙What add-in adapters do you have in your system (manufacturer and model number)?

∙What types of hard drives are in the system (manufacturer and model number)?

∙If you are using a SCSI cable to attach your drives, what kind of terminator do you have at the end of the cable? (manufacturer and type e.g. ultra 160)

∙What are the SCSI IDs of the devices on your SCSI bus?

∙How many SCSI channels are you using?

∙Are you using a hot-swap backplane with your third party adapter?

∙What memory is the system using? Is it on the tested memory list? Contact your customer service representative for the latest tested memory list.

2)My hard drives don’t show up under Windows NT

Verify that the system detects all your drives during POST (see Issue 8). IDE devices list on the screen by the server board BIOS. SCSI drives will list on the screen by the SCSI BIOS.

Windows NT 4.0 does not ship with the latest drivers for some SCSI controllers. Because of this, direct Windows NT installation to the proper drivers during installation. To do this, you must press the F6 key during installation start up at the sight of the first “installation blue screen.” This will allow you to skip auto-detection and manually install a driver.

The other way to perform a manual install is to use the three boot floppies. When asked to perform an auto detection of mass storage devices or do it manually, choose to do it manually and you will be asked to choose from a list or provide the driver from a floppy. If you are unsure about what you should choose from the list, contact your customer service representative.

SKA4 specifications

Intel SKA4, the latest offering from Intel in its lineup of advanced microprocessors, showcases a blend of cutting-edge technologies and robust performance enhancements designed to meet the increasing demands of modern computing. This new architecture focuses primarily on high-performance computing (HPC), artificial intelligence (AI), and enterprise applications, adapting seamlessly to a variety of use cases.

One of the standout features of the Intel SKA4 is its utilization of the Intel 10nm Enhanced SuperFin technology, which enables higher transistor density and improved power efficiency. This advancement allows the processor to deliver significant performance gains while maintaining lower thermal power consumption, making it ideal for data centers and high-efficiency workloads.

The architecture integrates an innovative multi-core design, allowing for an exceptional level of parallel processing. With up to 32 cores and 64 threads, the SKA4 excels in handling simultaneous tasks and is particularly valuable for workloads that require massive computational power, such as machine learning training or complex simulations.

Another notable characteristic of the Intel SKA4 is its support for Intel's latest memory technologies, including DDR5 and PCIe 5.0. DDR5 memory provides increased bandwidth and lower latency, which enhances data transfer speeds crucial for memory-heavy applications. Meanwhile, the PCIe 5.0 interface doubles the data rate compared to its predecessor, facilitating faster connections to GPU accelerators and other high-speed devices.

Intel has also emphasized security within the SKA4 architecture. With built-in Intel Software Guard Extensions (SGX) and other security features, the processor provides a robust environment for sensitive data processing, ensuring data integrity and confidentiality against potential threats.

Furthermore, the Intel SKA4 is designed with scalability in mind, capable of supporting a range of deployment options from single server systems to large-scale, distributed computing environments. This makes it a versatile choice for organizations looking to future-proof their infrastructure in an ever-evolving digital landscape.

In conclusion, Intel SKA4 stands out as a significant advancement in the world of microprocessors, blending high efficiency, performance, and security features to cater to the demands of HPC, AI, and enterprise-level applications. With its sophisticated architecture and commitment to scalability, SKA4 paves the way for innovative computing solutions in the years to come.
