Persistent Memory Challenges with Memory Mode For more details on persistent memory support on VMware, please refer to: The advantages of Memory Mode are that applications can run unmodified, and that persistent memory offers lower latencies compared to the fastest storage devices. The total available memory capacity for use by vSphere and VMs is the amount of persistent memory available on the system. In Memory Mode, Intel CPUs utilize lower-latency DRAM as a cache-tier for contents stored in higher-latency Intel В® Optane в„ў PMem. With VMware vSphere 6.7EP10, VMware announced support for two different access modes supported by Intel В® Optane в„ў PMem вЂ“ Memory Mode and App-Direct Mode.В For more details, refer to: We will next explore how memory monitoring can play a key role in overcoming some of the challenges with adopting Intel В® Optane TM PMem.

A combination of DRAM and PMem has been found to suit most applications by providing the best latencies of DRAM while providing the increased capacity from PMem. P Mem (up to 3x cheaper than DRAM) helps reduce overall server costs for enterprises with the trade-off of higher latencies (order of 10s) compared to DRAM s. Intel В® Optane в„ў Persistent Memory (PMem) can provide the right balance between infrastructure cost and performance. Traditionally, applications such as large in-memory databases, OLTP/OLAP class applications have required large amounts of memory and there is often a difficult trade-off of cost and performance that customers must choose from, since Dynamic r andom вЂ“ a ccess m emory ( DRAM ) is often one of the most expensive components in the server infrastructure. These applications require large memory capacities and are also latency sensitive. to derive more business value out of the data, and these applications need to run in real-time for the results to make an impact, and for changes to be applied immediately to improve business results. Enterprises are adopting AI/ML applications, in-memory database applications etc. However, this phenomenon is presenting both opportunities and challenges for enterprises because while they want to extract maximum value from the generated data, they lack the associated infrastructure that can result in valid business outcomes.Д«usinesses have already started on their digital transformation journey with initiatives like application modernization, DevOps, data mobility, and as well as cloud and edge computing. This growth of data is primarily fueled by trends such as 5G, IoT, social media, and proliferation of mobile devices. In 2020 alone, 64.2 ZB of data was created or replicated.

IDC predicts that global data creation and replication will experience a CAGR of 23% until 2025*. Modern trends are changing the way people and businesses are interacting with technology.
