MemVerge MemoryViewer provides insight into memory and application usage

MemVerge has created a software program instrument that offers system directors a complete view of the bodily reminiscence topology and utility reminiscence utilization. MemVerge MemoryViewer, with its intuitive graphical interface, supplies a real-time view of reminiscence configuration and bandwidth for every sort of reminiscence gadget.

MemVerge MemoryViewer, with its intuitive graphical interface, supplies a real-time view of reminiscence configuration and bandwidth for every sort of reminiscence gadget.

Advanced reminiscence layouts

Server configurations, reminiscence mode, DIMM layouts, and BIOS configurations turn out to be complicated and complicated. Heterogeneous reminiscence gadgets, such because the Intel Optane PMem, solely add to the complexity. Up to now, reminiscence administration was restricted to monitoring capability and utilization and left efficiency points unresolved. Software program-defined capability, efficiency, and availability configuration created the necessity for larger visibility into reminiscence assets.

MemVerge MemoryViewer supplies a graphical or textual show of system reminiscence topology and efficiency to make sure that the configuration is optimized for the workload. Many fashionable functions require that methods be configured for big quantities of reminiscence. Nonetheless, in lots of circumstances, the processed knowledge makes use of solely a small portion of reminiscence at anybody time, leaving a lot of the reserved reminiscence unused or “chilly”.

Utilizing reminiscence layers, chilly knowledge might be saved in low-cost PMem, which reduces {hardware} prices by 30-40 p.c with none influence on utility efficiency. MemoryViewer comes with a graphical reminiscence map exhibiting reminiscence utilization patterns that may alert directors to misconfigurations and alternatives to enhance reminiscence configurations.

MemoryViewer for Linux is simple to put in, helps GUI and CLI, and is accessible in RPM or Debian (DEB) packages. With its intuitive graphical interface, the Linux-based MemVerge MemoryViewer detects reminiscence efficiency (DRAM and PMem) in actual time.

Monitor MemVerge MemoryViewer process

MemoryViewer shows scorching utility utilization versus chilly reminiscence utilization in order that system directors can decide the perfect reminiscence configurations. The workload proven within the MemoryViewer Reminiscence Heatmap generally solely makes use of the allotted reminiscence capability, making it a great candidate for tiered configuration of DRAM and PMem.

View MemVerge MemoryViewer Server

MemoryViewer reveals the bodily structure of the DIMM slots for every server socket, together with the place the DRAM and PMem DIMMs are put in. There are strict pointers about the place and what number of DRAM and PMem items might be configured. There are additionally directions for BIOS settings that should be met. MemoryViewer supplies system directors with a graphical show of whether or not the system is configured accurately.

MemVerge MemoryViewer handles the view

MemoryViewer could be a helpful troubleshooting instrument with the power to watch system reminiscence well being and use, and compile a historic document of how functions entry reminiscence, together with allocating, writing, studying, and releasing reminiscence pages. With MemoryViewer, system directors can correlate CPU utilization with learn or write reminiscence entry, examine every unit’s well being and read-write bandwidth, and present a timeline of PMem and total DRAM efficiency.

Prepared for what’s subsequent – CXL

Intel and AMD are getting ready to launch next-generation CPUs that function extra cores, help for DDR5 reminiscence, help for PCIe 5.0 that gives further CPU lanes, and Compute Categorical Hyperlink (CXL). CXL adjustments the dynamics round how DRAM is allotted inside the system.

CXL is an rising market with help from all main processor and reminiscence distributors. For the primary time, software program, aside from the working system, is required to handle reminiscence. With CXL, IT professionals want a planning instrument to evaluate their reminiscence utilization. With MemoryViewer, if it factors to a stranded reminiscence, pooling and sharing the reminiscence will improve utilization and scale back price.

The CXL 1.1 ships in subsequent technology servers from AMD and Intel and now there’s extra energy about CXL with the discharge of the most recent CXL 3.0 introduced at Flash Reminiscence Summit. MemVerge MemoryViewer was developed in anticipation of the influence of CXL.

The reminiscence viewer exhibits the bodily structure of the server. The screenshot above exhibits two DIMMs, 4 CXL reminiscence gadgets, and the bandwidth of each.

Compute Categorical Hyperlink (CXL) is an open customary inner connection that gives high-bandwidth, low-latency connectivity between host processors and gadgets equivalent to accelerators, reminiscence buffers, and sensible I/O gadgets. CXL is designed to deal with high-performance computational workloads by supporting heterogeneous processing and reminiscence methods that allow useful resource sharing to cut back total software program stack complexity, decrease system prices, and ship increased efficiency. When mixed with MemVerge software program, CXL supplies scalable, compositable, and accessible combination reminiscence.

The present CXL 2.0 specification supplies for reminiscence pooling by way of PCI-Categorical 5.0 peripheral interconnection, however there may be new hype across the just-released CXL 3.0 specification, which outperforms PCI-Categorical 6.0 connectivity and is anticipated in 2023 to supply 2X the bandwidth. In fact, techs are already wanting ahead to a different 2X of bandwidth that will include CXL 4.0 and PCI-Categorical 7.0 anticipated in 2025.

final ideas

Reminiscence is among the costliest parts in any server construct, however it’s also some of the obscure to know. Typically, it isn’t instantly clear to directors how a lot reminiscence functions are utilizing or whether or not there are functions or zombie processes that scale back system efficiency.

MemoryViewer from MemVerge helps sort out points like this, not simply with a considerable amount of info, however with a visually interesting GUI to associate with it. On high of that, they’re prepared for what’s to come back, with CXL help. CXL is altering the reminiscence recreation for the primary time in many years, so having a imaginative and prescient for this spending is vital.

MemVerge desires to create “essentially the most superior reminiscence visualization instrument on the planet”. Up to now they’ve achieved a fairly thorough job, with DRAM, PMem and CXL help. Though they need neighborhood suggestions. In case you are excited about checking MemoryViewer in your group, you possibly can get it free For CentOS 7 & 8, Ubuntu / Debian, or as a container. Be sure to ship your suggestions after you go to assist develop MemoryViewer.
