As an IT admin, one of the responsibilities you have is to ensure systems continue to run smoothly. That is true for a number of activities and components, such as monitoring if a disk is going to run out of space, determining how much memory and processing a Hyper-V host is consuming so you can plan for new VMs, and many other examples.
Dynamic Software Updating (DSU) Dynamic Software Updating (DSU) is a field of research pertaining to upgrading programs while they are running. DSU is not currently widely used in industry. However, researchers have developed a wide variety of systems and techniques for implementing DSU. These systems are commonly tested on real-world programs. Current operating systems and programming languages are typically not designed with DSU in mind. As such, DSU implementations commonly either utilize existing tools, or implement specialty compilers. These compilers preserve the semantics of the original program, but instrument either the source code or object code to produce a dynamically update-able program. Researchers compare DSU-capable variants of programs to the original program to assess safety and performance overhead. Software Hot-Swapping Hot swapping can also refer to the ability to alter the running code of a program without needing to interrupt its execution. Interactive programming is a programming paradigm that makes extensive use of hot swapping, so the programming activity becomes part of the program flow itself. Only a few programming languages support hot swapping natively, including Pike, Lisp, Erlang, Smalltalk, Visual Basic 6 (Not VB.net), Java and most recently Elm and Elixir. Microsoft Visual Studio supports a kind of hot swapping called Edit and Continue, which is supported by C#, VB.NET and C/C++ when running under a debugger. Hot swapping is the central method in live coding,...
Remote Direct Memory Access (RDMA) provides direct memory access from the memory of one host (storage or compute) to the memory of another host without involving the remote Operating System and CPU, boosting network and host performance with lower latency, lower CPU load and higher bandwidth. In contrast, TCP/IP communications typically require copy operations, which add latency and consume significant CPU and memory resources.

RecoverPoint for VMs is a virtualized solution that provides data replication, protection, and recovery within the VMware vSphere environment.
Enable quick recovery of VMware virtual machines to any point in time. Dell EMC RecoverPoint for Virtual Machines provides continuous data protection (CDP) for operational recovery and disaster recovery. You’ll manage your VM protection simply and efficiently.
This is not a new features on last vSphere version but I went to write a post about that. We had to deploy different replication scenarios for our customers and some customers needs Point-In-Time Recovery (PiT) and The PiT solutions using VAIO actually so learning about the API is necessary for administrators.
The vSphere APIs for I/O Filtering (VAIO) were introduced in vSphere 6.0 Update 1. The VAIO framework and program were developed to provide VMware and partners the ability to insert filters for I/O into the data path of virtual machines. These “I/O Filters” enable VMware, and partners, to intercept and manipulate the I/O. This manipulation can provide open-ended data services, but thus far is limited to four use cases, two of which are currently exclusive to VMware and two which are open for partners. These use cases are: Replication, Caching, Quality of service (VMware only), Encryption (VMware only).
If you have any version of Veeam Backup & Replication for protecting virtual machines in your virtual environment and using vSphere 4 and later, the below problem might happen to you.
vSAN ReadyNode are x86 servers, available from all the leading server vendors, that have been pre-configured, tested and certified for VMware Hyper-Converged Infrastructure Software.

VMware vSAN Hybrid TCO and Sizing Calculator Virtual SAN or vSAN is a software-defined storage (Hyper Converged) for VMware vSphere environments. Main goal of sing vSAN in VMware vSphere environments, is reducing implementing cost. So calculating TCO and device sizing will help to achieve better results. As vSAN technology owner, VMware has provided an online tool for calculating TCO and sizing for vSAN. The online tool is very useful for IT administrator to find cost of vSAN implementation with different scenarios. The online tool has four different sections: Sizing Inputs: You should fill the sizing inputs form with some information about your environment. Sizing Results: The online tool will calculate results according to the sizing inputs and show the result on this section. TCO Input: You should enter required information for Total Cost of Ownership. TCO Results: According to the information, the tool will calculate and shows the result for TCO calculation. Sizing Inputs This section is using for enter virtualization environment specifications. You must specify the some important information for the online tool to calculating vSAN TCO and sizing. The online tool can calculate requirements according to virtualization platform, there is two platforms for calculations: Server Virtualization Desktop Virtualization The online...
EMC Unity Drive and OE Compatibility Matrix EMC Unity storage systems supporting the below disk drives: Unity SAS Flash 2 Drives – For use in FAST Cache, FAST VP or all-Flash-pools Unity SAS Flash 3 Drives – For use in all-Flash-pools only Unity SAS Flash 4 Drives – For use in all-Flash-pools only Unity Spinning Drives To function properly drives installed in an EMC Unity storage system require that the array be running the minimum required revision of the Operating Environment (OE). EMC provides a document which lists the drive part numbers supported for Unity storage systems and the minimum software revisions required for each drive model. Notes: The drive part number (PN) appears on a label on the front of the drive carrier. Note that although the OE GUI may display an alpha suffix at the end of the PN (like EFD) these characters are not part of the actual orderable PN. All drives listed in this document are RoHS compliant. Unity drive models use the following prefixes: D3 = AC storage D3FC = AC FAST cache D3AF = AC storage when used in All-Flash-Array (AFA) D3N = DC NEBS storage D3NFC = DC NEBS FAST Cache The following...
