Microsoft Hyper-V Is Alive Enhanced With Windows Server 2025

Yes, you read that correctly, Microsoft Hyper-V is alive and enhanced with Windows Server 2025, formerly Windows Server v.Next server. Note that  Windows Server 2025 preview build is just a preview available for download testing as of this time.

What about Myth Hyper-V is discontinued?

Despite recent FUD (fear, uncertainty, doubt), misinformation, and fake news, Microsoft Hyper-V is not dead. Nor has Hyper-V been discontinued, as some claim. Some Hyper-V FUD is tied to customers and partners of VMware following Broadcom’s acquisition of VMware looking for alternatives. More on Broadcom and VMware here, here, here, here, and here.

As a result of Broadcom’s VMware acquisition and challenges for partners and customers (see links above), organizations are doing due diligence, looking for replacement or alternatives. In addition, some vendors are leveraging the current VMware challenges to try and position themselves as the best hypervisor virtualization safe harbor for customers. Thus some vendors, their partners, influencers and amplifiers are using FUD to keep prospects from looking at or considering Hyper-V.

Virtual FUD (vFUD)

First, let’s shut down some Virtual FUD (vFUD). As mentioned above, some are claiming that Microsoft has discontinued Hyper-V. Specifically, the vFUD centers on Microsoft terminating a specific license SKU (e.g., the free Hyper-V Server 2019 SKU). For those unfamiliar with the discontinued SKU (Hyper-V Server 2019), it’s a headless (no desktop GUI) version of Windows Server  running Hyper-V VMs, nothing more, nothing less.

Does that mean the Hyper-V technology is discontinued? No.

Does that mean Windows Server and Hyper-V are discontinued? No.

Microsoft is terminating a particular stripped-down Windows Server version SKU (e.g. Hyper-V Server 2019) and not the underlying technology, including Windows Server and Hyper-V.

To repeat, a specific SKU or distribution (Hyper-V Server 2019) has been discontinued not Hyper-V. Meanwhile, other distributions of Windows Server with Hyper-V continue to be supported and enhanced, including the upcoming Windows Server 2025 and Server 2022, among others.

On the other hand, there is also some old vFUD going back many years, or a decade, when some last experienced using, trying, or looking at Hyper-V. For example, the last look at Hyper-V might been in the Server 2016 or before era.

If you are a vendor or influencer throwing vFUD around, at least get some new vFUD and use it in new ways. Better yet, up your game and marketing so you don’t rely on old vFUD. Likewise, if you are a vendor partner and have not extended your software or service support for Hyper-V, now is a good time to do so.

Watch out for falling into the vFUD trap thinking Hyper-V is dead and thus miss out on new revenue streams. At a minimum, take a look at current and upcoming enhancements for Hyper-V doing your due diligence instead of working off of old vFUD.

Where is Hyper-V being used?

From on-site (aka on-premises, on-premises, on-prem) and edge on Windows Servers standalone and clustered, to Azure Stack HCI. From Azure, and other Microsoft platforms or services to Windows Desktops, as well as home labs, among many other scenarios.

Do I use Hyper-V? Yes, when I  retired from the vExpert program after ten years. I moved all of my workloads from VMware environment to Hyper-V including *nix, containers and Windows VMs, on-site and on Azure Cloud.

How Hyper-V Is Alive Enhanced With Windows Server 2025

Is Hyper-V Alive Enhanced With Windows Server 2025?  Yup.

Formerly known as Windows Server v.Next, Microsoft announced the Windows Server 2025 preview build on January 26, 2024 (you can get the bits here). Note that Microsoft uses Windows Server v.Next as a generic placeholder for next-generation Windows Server technology.

A reminder that the cadence of Windows Server Long Term Serving Channels (LTSC) versions has been about three years (2012R2, 2016, 2019, 2022, now 2025), along with interim updates.

What’s enhanced with Hyper-V and Windows Server 2025

    • Hot patching of running server (requires Azure Arc management) with almost instant implementations and no reboot for physical, virtual, and cloud-based Windows Servers.
    • Scaling of even more compute processors and RAM for VMs.
    • Server Storage I/O performance updates, including NVMe optimizations.
    • Active Directory (AD) improvements for scaling, security, and performance.
    • There are enhancements to storage replica and clustering capabilities.
    • Hyper-V GPU partition and pools, including migration of VMs using GPUs.

More Enhancements for Hyper-V and Windows Server 2025

Active Directory (AD)

Enhanced performance using all CPUs in a process group up to 64 cores to support scaling and faster processing. LDAP for TLS 1.3, Kerberos support for AES SHA 256 / 384, new AD functional levels, local KDC, improved replication priority, NTLM retirement, local Kerberos, and other security hardening. In addition, 64-bit Long value IDs (LIDs) are supported along with a new database schema using 32K pages vs the previous 8K pages. You will need to upgrade forest-wide across domain controllers to leverage the new larger page sizes (at least Server 2016 or later). Note that there is also backward compatibility using 8K pages until all ADs are upgraded.

Storage, HA, and Clustering

Windows Server continues to offer flexible options for storage how you want or need to use it, from traditional direct attached storage (DAS) to Storage Area Networks (SAN), to Storage Spaces Direct (S2D) software-defined, including NVMe, NVMe over Fabrics (NVMeoF), SAS, Fibre Channel, iSCSI along with file attached storage. Some other storage and HA enhancements include Storage Replica performance for logging and compression and stretch S2D multi-site optimization.

Failover Cluster enhancements include AD-less clusters, cert-based VM live migration for the edge, cluster-aware updating reliability, and performance improvements. ReFS enhancements include dedupe and compression optimizations.

Other NVMe enhancements include optimization to boost performance while reducing CPU overhead, for example, going from 1.1M IOPS to 1.86M IOPS, and then with a new native NVMe driver (to be added), from 1.1M IOPs to 2.1M IOPs. These performance optimizations will be interesting to look at closer, including baseline configuration, number and type of devices used, and other considerations.

Compute, Hyper-V, and Containers

Microsoft has added and enhanced various Compute, Hyper-V, and Container functionality with Server 2025, including supporting larger configurations and more flexibility with GPUs. There are app compatibility improvements for containers that will be interesting to see and hear more details about besides just Nano (the ultra slimmed-down Windows container).

Hyper-V

Microsoft extensively uses Hyper-V technology across different platforms, including Azure, Windows Servers, and Desktops. In addition, Hyper-V is commonly found across various customer and partner deployments on Windows Servers, Desktops, Azure Stack HCI, running on other clouds, and virtualization (nested). While Microsoft effectively leverages Hyper-V and continues to enhance it, its marketing has not effectively told and amplified the business benefit and value, including where and how Hyper-V is deployed.

Hyper-V with Server 2025 includes discrete device assignment to VM (e.g., resources dedicated to VMs). However, dedicating a device like a GPU to a VM prevents resource sharing, failover cluster, or live migration. On the other hand, Server 2025 Hyper-V supports GPU-P (GPU Partitioning), enabling GPU(s) to be shared across multiple VMs. GPUs can be partitioned and assigned to VMs, with GPUs and GPU partitioning enabled across various hosts.

In addition to partitioning, GPUs can be placed into GPU pools for HA. Live migration and cluster failover (requires PCIe SR-IOV), AMD Lilan or later, Intel Sapphire Rapids, among other requirements, can be done. Another enhancement is Dynamic Processor Compatibility, which allows mixed processor generations to be used across VMs and then masks out functionalities that are not common across processors. Other enhancements include optimized UEFI, secure boot, TPM , and hot add and removal of NICs.

Networking

Network ATC provides intent-based deployments where you specify desired outcomes or states, and the configuration is optimized for what you want to do. Network HUD enables always-on monitoring and network remediation. Software Defined Network (SDN) optimization for transparent multi-site L2 and L3 connectivity and improved SDN gateway performance enhancements.

SMB over QUIC leverages TLS 1.3 security to streamline local, mobile, and remote networking while enhancing security with configuration from the server or client. In addition, there is an option to turn off SMB NTLM at the SMB level, along with controls on which versions of SMB to allow or refuse. Also being added is a brute force attack limiter that slows down SMB authentication attacks.

Management, Upgrades, General user Experience

The upgrade process moving forward with Windows Server 2025 is intended to be seamless and less disruptive. These enhancements include hot patching and flighting (e.g., LTSC Windows server upgrades similar to how you get regular updates). For hybrid management, an easier-to-use wizard to enable Azure Arc is planned. For flexibility, if present, WiFi networking and Bluetooth devices are automatically enabled with Windows Server 2025 focused on edge and remote deployment scenarios.

Also new is an optional subscription-based licensing model for Windows Server 2025 while retaining the existing perpetual use. Let me repeat that so as not to create new vFUD, you can still license Windows Server (and thus Hyper-V) using traditional perpetual models and SKUs.

What this all means

Hyper-V is very much alive, and being enhanced. Hyper-V is being used from Microsoft Azure to Windows Server and other platforms at scale, and in smaller environments.

If you are looking for alternatives to VMware or simply exploring virtualization options, do your due diligence and check out Hyper-V. Hyper-V may or may not be what you want; however, is it what you need? Looking at Hyper-V now and upcoming enhancements also positions you when asked by management if you have done your due  diligence vs relying on vFUD.

Do a quick Proof of Concept, spin up a lab, and check out currently available Hyper-V. For example, on Server 2022 or 2025 preview, to get a feel for what is there to meet your needs and wants. Download the bits and get some hands on time with Hyper-V and Windows Server 2025.

Wrap up

Hyper-V is alive and enhanced with Windows Server 2025 and other releases.

Ok, nuff said, for now.

VMware vSAN 6.6 hyper-converged (HCI) software defined data infrastructure

server storage I/O trends

VMware vSAN 6.6 hyper-converged (HCI) software defined data infrastructure

In case you missed it, VMware announced vSAN v6.6 hyper-converged infrastructure (HCI) software defined data infrastructure solution. This is the first of a five-part series about VMware vSAN V6.6. Part II (just the speeds feeds please) is located here, part III (reducing cost and complexity) located here, part IV (scaling ROBO and data centers today) found here, as well as part V here (VMware vSAN evolution, where to learn more and summary).

VMware vSAN 6.6
Image via VMware

For those who are not aware, vSAN is a VMware virtual Storage Area Network (e.g. vSAN) that is software-defined, part of being a software-defined data infrastructure (SDDI) and software-defined data center (SDDC). Besides being software-defined vSAN is HCI combining compute (server), I/O networking, storage (space and I/O) along with hypervisors, management, and other tools.

Software-defined data infrastructure

Excuse Me, What is vSAN and who is if for

Some might find it odd having to explain what vSAN is, on the other hand, not everybody is dialed into the VMware world ecosystem, so let’s give them some help, for everybody else, and feel free to jump ahead.

For those not familiar, VMware vSAN is an HCI software-defined storage solution that converges compute (hypervisors and server) with storage space capacity and I/O performance along with networking. Being HCI means that with vSAN as you scale compute, storage space capacity and I/O performance also increases in an aggregated fashion. Likewise, increase storage space capacity and server I/O performance you also get more compute capabilities (along with memory).

For VMware-centric environments looking to go CI or HCI, vSAN offers compelling value proposition leveraging known VMware tools and staff skills (knowledge, experience, tradecraft). Another benefit of vSAN is the ability to select your hardware platform from different vendors, a trend that other CI/HCI vendors have started to offer as well.

CI and HCI data infrastructure

Keep in mind that fast applications need a fast server, I/O and storage, as well as server storage I/O needs CPU along with memory to generate I/O operations (IOPs) or move data. What this all means is that HCI solutions such as VMware vSAN combine or converge the server compute, hypervisors, storage file system, storage devices, I/O and networking along with other functionality into an easy to deploy (and management) turnkey solution.

Learn more about CI and HCI along with who some other vendors are as well as considerations at www.storageio.com/converge. Also, visit VMware sites to find out more about vSphere ESXi hypervisors, vSAN, NSX (Software Defined Networking), vCenter, vRealize along with other tools for enabling SDDC and SDDI.

Give Me the Quick Elevator Pitch Summary

VMware has enhanced vSAN with version 6.6 (V6.6) enabling new functionality, supporting new hardware platforms along with partners, while reducing costs, improving scalability and resiliency for SDDC and SDDI environments. This includes from small medium business (SMB) to mid-market to small medium enterprise (SME) as well as workgroup, departmental along with Remote Office Branch Office (ROBO).

Being a HCI solution, management functions of the server, storage, I/O, networking, hypervisor, hardware, and software are converged to improve management productivity. Also, vSAN integrated with VMware vSphere among other tools enable modern, robust data infrastructure that serves, protect, preserve, secure and stores data along with their associated applications.

Where to Learn More

The following are additional resources to learn more about vSAN and related technologies.

What this all means

Overall a good set of enhancements as vSAN continues its evolution looking back just a few years ago, to where it is today and will be in the future. If you have not looked at vSAN recently, take some time beyond reading this piece to learn some more.

VMware vSAN V6.6 Part III (reducing costs complexity)

server storage I/O trends

VMware vSAN V6.6 Part III (Reducing costs complexity)

In case you missed it, VMware announced vSAN v6.6 hyper-converged infrastructure (HCI) software defined data infrastructure solution. This is the third of a five-part series about VMware vSAN V6.6. View Part I here, Part II (just the speeds feeds please) is located here, part IV (scaling ROBO and data centers today) found here, as well as part V here (VMware vSAN evolution, where to learn more and summary).

For those who are not aware, vSAN is a VMware virtual Storage Area Network (e.g. vSAN) that is software-defined, part of being a software-defined data infrastructure (SDDI) and software-defined data center (SDDC). Besides being software-defined vSAN is HCI combining compute (server), I/O networking, storage (space and I/O) along with hypervisors, management, and other tools.

Reducing cost and complexity

Reducing your total cost of ownership (TCO) including lower capital expenditures (CapEx) and operating (OPEX). VMware is claiming CapEx and OpEx reduced TCO of 50%. Keep in mind that solutions such as vSAN also can help drive return on investment (ROI) as well as return on innovation (the other ROI) via improved productivity, effectiveness, as well as efficiencies (savings). Another aspect of addressing TCO and ROI includes flexibility leveraging stretched clusters to address HA, BR, BC and DR Availability needs cost effectively. These enhancements include efficiency (and effectiveness e.g. productivity) at scale, proactive cloud analytics, and intelligent operations.

VMware vSAN stretch cluster
Image via VMware

Low cost (or cost-effective) Local, Remote Resiliency and Data Protection with Stretched Clusters across sites. Upon a site failure, vSAN maintains availability is leveraging surviving site redundancy. For performance and productivity effectiveness, I/O traffic is kept local where possible and practical, reducing cross-site network workload. Bear in mind that the best I/O is the one you do not have to do, the second is the one with the least impact.

This means if you can address I/Os as close to the application as possible (e.g. locality of reference), that is a better I/O. On the other hand, when data is not local, then the best I/O is the one involving a local or remote site with least overhead impact to applications, as well as server storage I/O (including networks) resources. Also keep in mind that with vSAN you can fine tune availability, resiliency and data protection to meet various needs by adjusting fault tolerant mode (FTM) to address a different number of failures to tolerate.

server storage I/O locality of reference

Network and cloud friendly Unicast Communication enhancements. To improve performance, availability, and capacity (CPU demand reduction) multicast communications are no longer used making for easier, simplified single site and stretched cluster configurations. When vSAN clusters upgrade to V6.6 unicast is enabled.

VMware vSAN unicast

Gaining insight, awareness, adding intelligence to avoid flying blind, introducing vSAN Cloud Analytics and Proactive Guidance. Part of a VMware customer, experience improvement program, leverages cloud-based health checks for easy online known issue detection along with relevant knowledge bases pieces as well as other support notices. Whether you choose to refer to this feature as advanced analytics, artificial intelligence (AI), proactive rules enabled management problem isolation, solving resolution I will leave that up to you.

VMware vSAN cloud analytics
Image via VMware

Part of the new tools analytics capabilities and prescriptive problem resolution (hmm, some might call that AI or advanced analytics, just saying), health check issues are identified, notifications along with suggested remediation. Another feature is the ability to leverage continuous proactive updates for advance remediation vs. waiting for subsequent vSAN releases. Net result and benefit are reducing time, the complexity of troubleshooting converged data infrastructure issues spanning servers, storage, I/O networking, hardware, software, cloud, and configuration. In other words, enable you more time to be productive vs. finding and fixing problems leveraging informed awareness for smart decision-making.

VMware vSAN V6.6 Part IV (HCI scaling ROBO and data centers today)

server storage I/O trends

VMware vSAN V6.6 Part IV (HCI scaling ROBO and data centers today)

In case you missed it, VMware announced vSAN v6.6 hyper-converged infrastructure (HCI) software defined data infrastructure solution. This is the fourth of a five-part series about VMware vSAN V6.6. View Part I here, Part II (just the speeds feeds please) is located here, part III (reducing cost and complexity) located here, as well as part V here (VMware vSAN evolution, where to learn more and summary).

For those who are not aware, vSAN is a VMware virtual Storage Area Network (e.g. vSAN) that is software-defined, part of being a software-defined data infrastructure (SDDI) and software-defined data center (SDDC). Besides being software-defined vSAN is HCI combining compute (server), I/O networking, storage (space and I/O) along with hypervisors, management, and other tools.

Scaling HCI for ROBO and data centers today and for tomorrow

Scaling with stability for today and tomorrow. This includes addressing your applications Performance, Availability, Capacity and Economics (PACE) workload requirements today and for the future. By scaling with stability means boosting performance, availability (data protection, security, resiliency, durable, FTT), effective capacity without one of those attributes compromising another.

VMware vSAN data center scaling

Scaling today for tomorrow also means adapting to today’s needs while also flexible to evolve with new application workloads, hardware as well as a cloud (public, private, hybrid, inter and intra-cloud). As part of continued performance improvements, enhancements to optimize for higher performance flash SSD including NVMe based devices.

VMware vSAN cloud analytics
Image via VMware

Part of scaling with stability means enhancing performance (as well as productivity) or the effectiveness of a solution. Keep in mind that efficiency is often associated with storage (or server or network) space capacity savings or reductions. In that context then effectiveness means performance and productivity or how much work can be done with least overhead impact. With vSAN, V6.6 performance enhancements include reduced checksum overhead, enhanced compression, and deduplication, along with destaging optimizations.

Other enhancements that help collectively contribute to vSAN performance improvements include VMware object handling (not to be confused with cloud or object storage S3 or Swift objects) as well as faster iSCSI for vSAN. Also improved are more accurate refined cache sizing guidelines. Keep in mind that a little bit of NAND flash SSD or SCM in the right place can have a significant benefit, while a lot of flash cache costs much cash.

Part of enabling and leveraging new technology today includes support for larger capacity 1.6TB flash SSD drives for cache, as well as lower read latency with 3D XPoint and NVMe drives such as those from Intel among others. Refer to the VMware vSAN HCL for current supported devices which continue evolve along with the partner ecosystem. Future proofing is also enabled where you can grow from today to tomorrow as new storage class memories (SCM) among other flash SSD as well as NVMe enhanced storage among other technologies are introduced into the market as well as VMware vSAN HCL.

VMware vSAN and data center class applications
Image via VMware

Traditional CI and in particular many HCI solutions have been optimized or focused on smaller application workloads including VDI resulting in the perception that HCI, in general, is only for smaller environments, or larger environment non-mission critical workloads. With vSAN V6.6 VMware is addressing and enabling larger environment mission critical applications including Intersystem Cache medical health management software among others. Other application workload extensions including support for higher performance demanding Hadoop big data analytics, a well as extending virtual desktop infrastructure (VDI) workspace with XenDesktop/XenApp, along with Photon 1.1 container support.

What about VMware vSAN 6.6. Packaging and License Options

As part of vSAN 6.6 VMware several solution bundle packaged options for the data center as well as smaller ROBO environment. Contact your VMware representative or partner to learn more about specific details.

VMware vSAN V6.6 Part V (vSAN evolution and summary)

In case you missed it, VMware announced vSAN v6.6 hyper-converged infrastructure (HCI) software defined data infrastructure solution. This is the fifth of a five-part series about VMware vSAN V6.6. View Part I here, Part II (just the speeds feeds please) is located here, part III (reducing cost and complexity) found here, part IV (scaling ROBO and data centers today) located here.

For those who are not aware, vSAN is a VMware virtual Storage Area Network (e.g. vSAN) that is software-defined, part of being a software-defined data infrastructure (SDDI) and software-defined data center (SDDC). Besides being software-defined vSAN is HCI combining compute (server), I/O networking, storage (space and I/O) along with hypervisors, management, and other tools.

How has vSAN (formerly referred to as VSAN) Evolved

A quick recap of the VMware vSAN progression which first appeared as part of vSphere 5.5. (e.g. vSAN 5.5 can be thought of 1.0 in some ways) consists of several releases. Since vSAN is tightly integrated with VMware vSphere along with associated management tools, there is a correlation between enhancements to the underlying hypervisor, and added vSAN functionality. Keep in mind sometimes by seeing where something has been, helps to view where going.

Previous vSAN enhancements include:

  • 5.5 Hybrid (mixed HDD and flash)
  • 6.2 (2016) All flash (e.g. AFA) versions included data footprint reduction (DFR) technologies such as compression and dedupe along with performance Quality of Service (QoS) enhancements.
  • 6.5 Cross Cloud functionality including the announcement of container support, cloud-native apps, as well as upcoming vSphere, vSAN, NSX and other VMware software-defined data center (SDDC) and software-defined data infrastructure (SDDI) technology running natively on AWS (not on EC2) cloud infrastructure.
  • 6.6 Modern data infrastructure flexibility, scalability, resiliency, extensibility including performance, availability, capacity and economics (PACE).

V5.5

  • Distributed RAID
  • Per-VM SPBM
  • Set and change FTT via policy
  • In-kernel hyper-convergence engine
  • RVC and Observer

V6.0

  • All-flash architecture
  • Perf improvements (4xIOPS)
  • 64-node support
  • High-density storage blades
  • Fault domain awareness
  • Scalable snapshots and clones
  • Disk enclosure management

V6.1

  • Windows Failover Clustering
  • Oracle RAC support
  • HW checksum and encryption
  • 2-node ROBO mode
  • UltraDIMM and NVMe support
  • Stretch clusters
  • 5 min RPO (vSphere Rep)
  • SMP-FT support
  • Health Check, vROps, Log Insight

V6.2

  • IPv6 support
  • Software checksum
  • Nearline dedupe and compression on all-flash
  • Erasure coding on all-flash
  • QoS IOPS limits
  • Performance monitoring service

V6.5

  • iSCSI
  • 2-Node direct connect
  • PowerCLI
  • Public APIs and SDK
  • 512e support
  • All-Flash to all editions

Where to Learn More

The following are additional resources to find out more about vSAN and related technologies.

What this all means, wrap up and summary

VMware continues to extend the software-defined data center (SDDC) and Software-Defined Data Infrastructure (SDDI) ecosystem with vSAN to address the needs from smaller SMB and ROBO environments to larger SME and enterprise workloads. To me a theme with V6.6 is expanding resiliency, scalability with stability to expand vSAN upmarket as well as into new workloads similar to how vSphere has evolved.

With each new release, vSAN is increasing its feature, functionality, resiliency and extensiveness associated with traditional storage and non-CI or HCI solutions. Overall a good set of enhancements as vSAN continues its evolution looking back just a few years ago, to where it is today and will be in the future. If you have not looked at vSAN recently, take some time beyond reading this piece to learn some more.

Ok, nuff said (for now…).

VMware announces vSphere V6 and associated virtualization technologies

VMware announces vSphere V6 and associated virtualization technologies

server storage I/O trends

VMware has announced version 6 (V6) of its software defined data center (SDDC) server virtualization hypervisor called vSphere aka ESXi. In addition to a new version of its software defined server hypervisor along with companion software defined management and convergence tools.

VMware

VMware vSphere Refresh

As a refresh for those whose world does not revolve around VMware, vSphere and software defined data centers (believe it or not there are some who exist ;), ESXi is the hypervisor that virtualizes underlying physical machines (PM’s) known as hosts.

software defined data center convergence
The path to software defined data center convergence

Guest operating systems (or other hypervisors using nesting) run as virtual machines (VM’s) on top of the vSphere hypervisor host (e.g. ESXi software). Various VMware management tools (or third-party) are used for managing the virtualized data center from initial configuration, configuration, conversion from physical to virtual (P2V) or virtual to virtual (V2V) along with data protection, performance, capacity planning across servers, storage and networks.

virtual machines

VMware vSphere is flexible and can adapt to different sized environments from small office home office (SOHO) or small SMB, to large SMB, SME, enterprise or cloud service provider. There are a free version of ESXi along with paid versions that include support and added management tool features. Besides the ESXi vSphere hypervisor, other commonly deployed modules include the vCenter administration along with Infrastructure Controller services platform among others. In addition, there are optional solution bundles to add support for virtual networking, cloud (public and private), data protection (backup/restore, replication, HA, BC, DR), big data among other capabilities.

What is new with vSphere V6

VMware has streamlined the installation, configuration and deployment of vSphere along with associated tools which for smaller environments makes things simply easier. For the larger environments, having to do less means being able to do more in the same amount of time which results in cost savings. In addition to easier to use, deploy and configure, VMware has extended the scaling capabilities of vSphere in terms of scaling-out (larger clusters), scaling-up (more and larger servers), as well as scaling-down (smaller environments and ease of use).

cloud virtual software defined servers

  • Compute: Expanded support for new hardware, guest operating systems and general scalability in terms of physical, and virtual resources. For example increasing the number of virtual CPU (vCPUs), number of cluster nodes among other speeds and feeds enhancements.

server storage I/O vsan

  • Storage: This is an area where several enhancements were made including updates for Storage I/O controls (Storage QoS and performance optimizations) with per VM reservations, NFS v4.1 with Kerberos client, Virtual SAN (VSAN) improvements (new back-end underlying file system) as well as new Virtual Volumes (vVOLs) for Storage Policy Based Management.
  • Availability: Improvements for vMotion (ability to live move virtual machines between physical servers (vmware hosts) including long distance fault-tolerance. Other improvements include faster replication, vMotion across vCenter servers, and long distance vMotion (up to 100ms round trip time latency).
  • Network: Network I/O Control (NIOC) provides per VM and dat (VM and data repository) bandwidth reservations for quality of service (QoS) performance optimization.
  • Management: Improvements for multi-site, virtual data centers, content-library (storage and versioning of files and objects including ISOs and OVFs (Open Virtualization Format files) that can be on a VMFS (VMware File System) dat or NFS volume, policy-based management and web-client performance enhancements.

What is vVOL?

The quick synopsis of VMware vVOL’s overview:

  • Higher level of abstraction of storage vs. traditional SCSI LUN’s or NAS NFS mount points
  • Tighter level of integration and awareness between VMware hypervisors and storage systems
  • Simplified management for storage and virtualization administrators
  • Removing complexity to support increased scaling
  • Enable automation and service managed storage aka software defined storage management

server storage I/O volumes
How data storage access and managed via VMware today (read more here)

vVOL’s are not LUN’s like regular block (e.g. DAS or SAN) storage that use SAS, iSCSI, FC, FCoE, IBA/SRP, nor are they NAS volumes like NFS mount points. Likewise vVOL’s are not accessed using any of the various object storage access methods mentioned above (e.g. AWS S3, Rest, CDMI, etc) instead they are an application specific implementation. For some of you this approach of an applications specific or unique storage access method may be new, perhaps revolutionary, otoh, some of you might be having a DejaVu moment right about now.

vVOL is not a LUN in the context of what you may know and like (or hate, even if you have never worked with them), likewise it is not a NAS volume like you know (or have heard of), neither are they objects in the context of what you might have seen or heard such as S3 among others.

Keep in mind that what makes up a VMware virtual machine are the VMK, VMDK and some other files (shown in the figure below), and if enough information is known about where those blocks of data are or can be found, they can be worked upon. Also keep in mind that at least near-term, block is the lowest common denominator that all file systems and object repositories get built-up.

server storage I/O vVOL basics
How VMware data storage accessed and managed with vVOLs (read more here)

Here is the thing, while vVOL’s will be accessible via a block interface such as iSCSI, FC or FCoE or for that matter, over Ethernet based IP using NFS. Think of these storage interfaces and access mechanisms as the general transport for how vSphere ESXi will communicate with the storage system (e.g. their data path) under vCenter management.

What is happening inside the storage system that will be presented back to ESXi will be different than a normal SCSI LUN contents and only understood by VMware hypervisor. ESXi will still tell the storage system what it wants to do including moving blocks of data. The storage system however will have more insight and awareness into the context of what those blocks of data mean. This is how the storage systems will be able to more closely integrate snapshots, replication, cloning and other functions by having awareness into which data to move, as opposed to moving or working with an entire LUN where a VMDK may live.

Keep in mind that the storage system will still function as it normally would, just think of vVOL as another or new personality and access mechanism used for VMware to communicate and manage storage. Watch for vVOL storage provider support from the who’s who of existing and startup storage system providers including Cisco, Dell, EMC, Fujitsu, HDS, HP, IBM, NetApp, Nimble and many others. Read more about Storage I/O fundamentals here and vVOLs here and here.

What this announcement means

Depending on your experiences, you might use revolutionary to describe some of the VMware vSphere V6 features and functionalities. Otoh, if you have some Dejavu moments looking pragmatically at what VMware is delivering with V6 of vSphere executing on their vision, evolutionary might be more applicable. I will leave it up to you do decide if you are having a Dejavu moment and what that might pertain to, or if this is all new and revolutionary, or something more along the lines of technolutionary.

VMware continues to execute delivering on the Virtual Data Center aka Software Defined Data Center paradigm by increasing functionality, as well as enhancing existing capabilities with performance along with resiliency improvements. These abilities enable the aggregation of compute, storage, networking, management and policies for enabling a global virtual data center while supporting existing along with new emerging applications.

Server and Storage I/O Benchmarking 101 for Smarties

Server Storage I/O Benchmarking 101 for Smarties or dummies ;)

server storage I/O trends

This is the first of a series of posts and links to resources on server storage I/O performance and benchmarking (view more and follow-up posts here).

The best I/O is the I/O that you do not have to do, the second best is the one with the least impact as well as low overhead.

server storage I/O performance

Drew Robb (@robbdrew) has a Data Storage Benchmarking Guide article over at Enterprise Storage Forum that provides a good framework and summary quick guide to server storage I/O benchmarking.

Via Drew:

Data storage benchmarking can be quite esoteric in that vast complexity awaits anyone attempting to get to the heart of a particular benchmark.

Case in point: The Storage Networking Industry Association (SNIA) has developed the Emerald benchmark to measure power consumption. This invaluable benchmark has a vast amount of supporting literature. That so much could be written about one benchmark test tells you just how technical a subject this is. And in SNIA’s defense, it is creating a Quick Reference Guide for Emerald (coming soon).

But rather than getting into the nitty-gritty nuances of the tests, the purpose of this article is to provide a high-level overview of a few basic storage benchmarks, what value they might have and where you can find out more. 

Read more here including some of my comments, tips and recommendations.

Drew’s provides a good summary and overview in his article which is a great opener for this first post in a series on server storage I/O benchmarking and related resources.

You can think of this series (along with Drew’s article) as server storage I/O benchmarking fundamentals (e.g. 101) for smarties (e.g. non-dummies ;) ).

Note that even if you are not a server, storage or I/O expert, you can still be considered a smarty vs. a dummy if you found the need or interest to read as well as learn more about benchmarking, metrics that matter, tools, technology and related topics.

Server and Storage I/O benchmarking 101

There are different reasons for benchmarking, such as, you might be asked or want to know how many IOPs per disk, Solid State Device (SSD), device or storage system such as for a 15K RPM (revolutions per minute) 146GB SAS Hard Disk Drive (HDD). Sure you can go to a manufactures website and look at the speeds and feeds (technical performance numbers) however are those metrics applicable to your environments applications or workload?

You might get higher IOPs with smaller IO size on sequential reads vs. random writes which will also depend on what the HDD is attached to. For example are you going to attach the HDD to a storage system or appliance with RAID and caching? Are you going to attach the HDD to a PCIe RAID card or will it be part of a server or storage system. Or are you simply going to put the HDD into a server or workstation and use as a drive without any RAID or performance acceleration.

What this all means is understanding what it is that you want to benchmark test to learn what the system, solution, service or specific device can do under different workload conditions.

Some benchmark and related topics include

  • What are you trying to benchmark
  • Why do you need to benchmark something
  • What are some server storage I/O benchmark tools
  • What is the best benchmark tool
  • What to benchmark, how to use tools
  • What are the metrics that matter
  • What is benchmark context why does it matter
  • What are marketing hero benchmark results
  • What to do with your benchmark results

    • server storage I/O benchmark step test
    Example of a step test results with various workers and workload

  • What do the various metrics mean (can we get a side of context with them metrics?)
  • Why look at server CPU if doing storage and I/O networking tests
  • Where and how to profile your application workloads
  • What about physical vs. virtual vs. cloud and software defined benchmarking
  • How to benchmark block DAS or SAN, file NAS, object, cloud, databases and other things
  • Avoiding common benchmark mistakes
  • Tips, recommendations, things to watch out for
  • What to do next

The following are related links to read more about server (cloud, virtual and physical) storage I/O benchmarking tools, technologies and techniques.

Wrap up and summary

We have just scratched the surface when it comes to benchmarking cloud, virtual and physical server storage I/O and networking hardware, software along with associated tools, techniques and technologies. However hopefully this and the links for more reading mentioned above give a basis for connecting the dots of what you already know or enable learning more about workloads, synthetic generation and real-world workloads, benchmarks and associated topics. Needless to say there are many more things that we will cover in future posts (e.g. keep an eye on and bookmark the server storage I/O benchmark tools and resources page here).

EMC VMAX 10K, looks like high-end storage systems are still alive

StorageIO industry trends cloud, virtualization and big data

This is the first in a multi-part series of posts looking at if large enterprise and legacy storage systems are dead, along with what todays EMC VMAX 10K updates means.

EMC has announced an upgrade, refresh or new version of their previously announced Virtual matrix (VMAX) 10,000 (10K), part of the VMAX family of enterprise class storage systems formerly known as DMX (Direct Matrix) and Symmetrix. I will get back to more coverage on the VMAX 10K and other EMC enhancements in a few moments in part two and three of this series.

Have you heard the industry myth about the demise or outright death of traditional storage systems? This has been particularly the case for high-end enterprise class systems, which by the way which were first, declared dead back in the mid-1990s then at the hands of emerging mid-range storage systems.

Enterprise class storage systems include EMC VMAX, Fujitsu Eternus DX8700, HDS, HP XP P9000 based on the HDS high-end product (OEM from HDS parent Hitachi Ltd.). Note that some HPers or their fans might argue that the P10000 (formerly known as 3PAR) declared as tier 1.5 should also be on the list; I will leave that up to you to decide.

Let us not forget the IBM DS8000 series (whose predecessors was known as the ESS and VSS before that); although some IBMers will tell you that XIV should also be in this list. High-end enterprise class storage systems such as those mentioned above are not alone in being declared dead at the hands of new all solid-state devices (SSD) and their startup vendors, or mixed and hybrid-based solutions.

Some are even declaring dead due to new SSD appliances or systems, and by storage hypervisor or virtual storage array (VSA) the traditional mid-range storage systems that were supposed to have killed off the enterprise systems a decade ago (hmm, DejaVu?).

The mid-range storage systems include among others block (SAN and DAS) and file (NAS) systems from Data Direct Networks (DDN), Dell Complement, EqualLogic and MD series (Netapp Engenio based), EMC VNX and Isilon, Fujitsu Eternus, and HDS HUS mid-range formerly known as AMS. Let us not forget about HP 3PAR or P2000 (DotHill based) or P6000 (EVA which is probably being put out to rest). Then there are the various IBM products (their own and what they OEM from others), NEC, NetApp (FAS and Engenio), Oracle and Starboard (formerly known as Reldata). Note that there are many startups that could be in the above list as well if they were not considering the above to be considered dead, thus causing themselves to also be extinct as well, how ironic ;).

What are some industry trends that I am seeing?

  • Some vendors and products might be nearing the ends of their useful lives
  • Some vendors, their products and portfolios continue to evolve and expand
  • Some vendors and their products are moving into new or adjacent markets
  • Some vendors are refining where and what to sell when and to who
  • Some vendors are moving up market, some down market
  • Some vendors are moving into new markets, others are moving out of markets
  • Some vendors are declaring others dead to create a new market for their products
  • One size or approach or technology does not fit all needs, avoid treating all the same
  • Leverage multiple tools and technology in creative ways
  • Maximize return on innovation (the new ROI) by using various tools, technologies in ways to boost productivity, effectiveness while removing complexity and cost
  • Realization that cutting cost can result in reduced resiliency, thus look for and remove complexity with benefit of removing costs without compromise
  • Storage arrays are moving into new roles, including as back-end storage for cloud, object and other software stacks running on commodity servers to replace JBOD (DejaVu anyone?).

Keep in mind that there is a difference between industry adoption (what is talked about) and customer deployment (what are actually bought and used). Likewise there is technology based on GQ (looks and image) and G2 (functionality, experience).

There is also an industry myth that SSD cannot or has not been successful in traditional storage systems which in some cases has been true with some products or vendors. Otoh, some vendors such as EMC, NetApp and Oracle (among others) are having good success with SSD in their storage systems. Some SSD startup vendors have been more successful on both the G2 and GQ front, while some focus on the GQ or image may not be as successful (or at least yet) in the industry adoption vs. customer deployment game.

For the above mentioned storage systems vendors and products (among others), or at least for most of them there is still have plenty of life in them, granted their role and usage is changing including in some cases being found as back-end storage systems behind servers running virtualization, cloud, object storage and other storage software stacks. Likewise, some of the new and emerging storage systems (hardware, software, valueware, services) and vendors have bright futures while others may end up on the where are they now list.

Are high-end enterprise class or other storage arrays and systems dead at the hands of new startups, virtual storage appliances (VSA), storage hypervisors, storage virtualization, virtual storage and SSD?

Are large storage arrays dead at the hands of SSD?

Have SSDs been unsuccessful with storage arrays (with poll)?

 

Here are links to two polls where you can cast your vote.

Cast your vote and see results of if large storage arrays and systems are dead here.

Cast your vote and see results of if SSD has not been successful in storage systems.

So what about it, are enterprise or large storage arrays and systems dead?

Perhaps in some tabloids or industry myths (or that some wish for) or in some customer environments, as well as for some vendors or their products that can be the case.

However, IMHO for many other environments (and vendors) the answer is no, granted some will continue to evolve from legacy high-end enterprise class storage systems to mid-range or to appliance or VSA or something else.

There is still life many of the storage systems architectures, platforms and products that have been declared dead for over a decade.

Continue reading about the specifics of the EMC VMAX 10K announcement in the next post in this series here. Also check out Chucks EMC blog to see what he has to say.

Ok, nuff said (for now).

Whats your take on open virtualization alliance and VMware?

Have you heard about the open virtualization alliance (OVA), their kernel based virtual machine (KVM) and their diverse membership list?

If not, here is a link to the OVA FAQ, also take a moment and read this here that talks about OVA along with some perspectives commentary from others as well as myself.

Virtual Servers and Virtual Machines

Figure 1: Generic representation of virtual machines (VMs) and virtualized environment

In a nutshell, OVA can be seen by the faithful as a move or ploy to catch up and buck the success trend of VMware. To those who are not on the VMware bandwagon, this could be seen as a move to level the playing field for virtual machines, kernels and servers.

Yet to others, this can be seen as DejaVu to past attempts at operating systems or other technology alliances to bring parity to the ranks of those not at the top of the technology list of a particular topic, product or theme. For example, a decade or two ago, there were the various Unix groups (remember SCO etc?) that were attempted involving the late Ray Norda of Novell fame in a quest to battle Microsoft among others.

The industry road side is littered with alliances that either still exist yet collecting dust or that faltered. For storage people does anybody remember Aperi and how those in the IBM lead storage management alliance were all singing Kumbaya around a virtual campfire and later partnering with SNIA (Storage Networking Industry Association)? Speaking of SNIA, anybody remember the various supported solutions forums (SSFs) popular back in the early 2000s as a means to demonstrate and stimulate interoperability between different vendors technologies?

Alliances are not bad, however generally to be successful, they have to exist for the right reasons in addition to being well funded, have strong leadership that also means having clear objectives to minimize chances of compromise by committee. While we are talking about alliances, have you heard about the Open Data Center Alliance (ODCA)? The ODCA alliance of which StorageIO is a member is a bit different than many IT related groups in that it is customer or non vendor focused. ODCA has good potential for doing some interesting things as long as they do not get bogged down in bureaucracy as is to often the case with industry driven trade groups, associations or alliances.

Lets see how these and other alliances move forward or what becomes of them, not to mention the expanding awareness around virtualization, life beyond consolidation (and here).

Whats your take on OVA and other alliances?

Ok, nuff said for now.
