Organizations seek to affordably boost memory and lower TCO. Low-latency, high-performance Intel® Optane™ DC persistent memory meets these goals while still maintaining nearly the same performance levels found in DRAM-only configurations.
As data grows, the number of virtual machines (VMs) running databases and the number of VMs per server also likely increases. Enterprises need to increase the VMs and databases per node to meet demand, and build VMs to handle larger datasets. Without sufficient memory resources, VM and application performance can suﬀer. It’s no surprise that application owners request high levels of memory allocation to protect their apps against possible workload surges and bottlenecks. While this is a conservative approach, it does not yield right-sized VM memory allocations, leaving organizations still searching for ways to boost memory capacity while lowering TCO.
Ideally, DRAM would be cheap and abundant, allowing database workloads to run in memory. But DRAM can be expensive, and the capacity of DRAM modules is not keeping up with application demand.
2nd Generation Intel® Xeon® Scalable processors with Intel® Optane™ DC persistent memory modules (DCPMMs) oﬀer an aﬀordable, higher-capacity alternative to conventional DRAM. Intel® Optane™ DCPMMs place low-latency, high-performance Intel® Optane™ media on a DDR4-format memory module, enabling higher total server memory capacities than DRAM alone. Greater memory capacities facilitate higher VM counts per server and server consolidation. Moreover, smart resource monitoring can lead to more right-sized allocation from these larger memory pools. These optimizations can lead to lower costs for hardware and licensing along with lower TCO, particularly for virtualized database solutions such as Microsoft SQL Server running under VMware vSphere. The low-latency, high-performance nature of Intel® Optane™ DC persistent memory allows for these benefits while still maintaining nearly the same service and performance levels found in DRAM-only configurations.
VMware-based or similar environments, especially those hosting database applications such as Microsoft SQL Server, can experience a wide array of benefits from expanding memory capacities beyond DRAM limitations with Intel® Optane™ DC persistent memory. At a time when technology trends demand VMs to support ever-larger sizes with no sacrifice in performance, Intel’s memory breakthrough provides a once-in-a-generation opportunity to surpass traditional architecture limitations, consolidate server resources (if desired), and significantly reduce TCO liabilities.
Intel® Optane™ DC persistent memory is an aﬀordable solution that drops right into existing DDR4 memory slots. IT can right-size DRAM allocations for the great majority of active datasets while using persistent memory module to allow for workload surges, maintain application resource allocations to application owners, and accommodate much larger workloads. IT can service an application owner’s memory requests, expand total memory per server, increase VM density, and dramatically improve resource utilization. These benefits ft perfectly with enterprises in the midst of their digital transformation. Companies working to modernize their infrastructure and increase their efficiency to meet the mounting wave of data demands and analyze it all need the new capabilities and benefits that Intel® Optane™ DC persistent memory can bring.
