New Hampshire Patent of the Month – July 2023
Cloud and edge data center traffic is growing at a high rate, requiring the innovations and technology surrounding it to grow just as rapidly. Drut Technologies Inc. is an early-stage company focused on matching this growth rate by developing a system to provide software defined resources on demand for the data center. They have recently been granted a patent for their novel solution for memory allocation and reallocation in server racks, offering increased flexibility and efficiency. Let’s delve into the details of their revolutionary disaggregated memory architecture.
Traditionally, server racks are built with fixed hardware boundaries, limiting their adaptability and leading to underutilization of resources over time. Drut Technologies has addressed this issue by introducing a memory disaggregation concept, allowing for the allocation and reallocation of memory resources based on the needs of each server.
The architecture consists of server sleds and memory sleds interconnected through a photonic cross-connect switch. Each server sled comprises a motherboard, memory modules, a cache, a CPU module, and an I/O hub. The memory sled, on the other hand, is separate from the server sleds and features its own motherboard, memory modules, memory controller, and fabric interface.
The key innovation lies in the memory sled’s ability to be disaggregated from the server sleds, providing additional memory resources that can be allocated based on demand. By utilizing the photonic cross-connect switch, memory blocks from the memory sled can be connected to any server sled, allowing for efficient utilization of memory resources.
This architecture offers several advantages. Firstly, it reduces the overbuilding of memory in servers, leading to cost savings in terms of capital and operating expenses. Instead of provisioning servers with excessive memory capacity, the disaggregated memory can be allocated dynamically, ensuring optimal resource utilization.
The disaggregated memory architecture enhances agility in resource allocation, making it ideal for cloud and edge data centers. With the ability to allocate memory resources based on workload requirements, this architecture maximizes performance and minimizes inefficiencies.
Drut Technologies has revolutionized the server rack landscape with their innovative disaggregated memory architecture. By enabling efficient memory allocation and reallocation, this solution empowers data center providers to deliver flexible and cost-effective services to end customers. With the potential to reduce energy consumption and carbon footprint, this architecture aligns with sustainability goals. It opens doors for collaborations among institutions and promotes widespread access to computing resources, driving digital transformation at various levels.
