ARM Processors may bring stacking servers with thousands of nodes, Red Hat's ARM chief architect predicts

From IDG News Service: Red Hat, an open-source software vendor, is paying close attention to the development of 64-bit ARM processors on servers to build professional capabilities on the emerging platform of data centers.

"You can't see us in today's commercial product market, but we have built capabilities beyond some of today's 64-bit technologies. So next, if we have a market that needs to be addressed, we will be able to respond, "said Jon Masters, Chief ARM designer at Red Hat. This was proposed by Masters at the usenix lisa (large-scale installation system management) meeting in Washington, DC on Friday.

The ARM processor represents "dramatic changes in computing," says Masters. Although it is already dominant in smartphones and embedded computing devices, the ARM processor architecture can also play a role in the data center. In the past year, ARM processor-based servers have begun to appear in the server market. HP has begun selling ARM-based Moonshot Series servers.

For data centers, ARM may bring about the ultra-large scale computing era due to its low power design, so that thousands of micro-computing nodes can be packaged into a stacked server. "In the near future, we will be able to establish a scale completely different from today's ." Said Masters.

ARM Processors may not run at the speed of x86 processors, but they can provide most of the performance and consume only a small amount of energy, this means that more processors can be packed in a small space. "You can use the same technology on your phone as part of the high-density server design," Masters said.

He said that many jobs do not require the fastest processor. Conversely, the workload can be distributed across more processors. "This has something to do with how much data I can move, not necessarily with how much computing I can do," he said. For example, the performance of cloud computing and Web applications running on multiple servers is the same as that of servers running on a small but faster number of servers.

ARM design also simplifies data center operations. The Design of ARM's chip system can solve the need to manage external components of many servers. For example, the ARM processor can provide cross-interconnection to reduce the need for external cables and top-level rack switches.

"Every blade has discrete cabling just around the corner," he said.

Masters said that ultra-large-scale computing still needs to do a lot of work.

ARM authorizes its architecture not to sell processors like intel. As a result, different ARM processors provided by different vendors have changed significantly. "There are a lot of unnecessary and unnecessary changes," says Masters. This may be a problem where a unified system is required to manage a collective data center.

Linaro is an industrial group dedicated to developing core open-source software for ARM platforms and some standardized ARM tasks. Red Hat engineers have played an important role. Linaro enterprise group, or LEG, has been striving to standardize software, this allows you to obtain a Linux version that can run ARM processors provided by different vendors." These are basic expectations in the enterprise field, "says Masters.

"We need to focus on how to make them fundamentally compatible so that you can further increase the stack," he said.

Another problem is the lack of standard 32-bit ARM processors for peripheral devices. Masters said LEG is considering using the 64-bit ARM processor's ACPI (Advanced Configuration and Power Interface) standard or UEFI (Unified extensible firmware interface ). Over time, ARM will provide capabilities similar to Automated Bus, such as a PCI bus that supports x86 machines.

Masters said Red Hat hasn't announced any notifications about when a Red Hat Enterprise Linux version of the ARM architecture will be released, but he makes it clear that, the ora community Linux release project for many RHEL applications has been tested, and a release version has been provided for ARM.
