The Next Generation Clusterless Federation Design in the Cloudistics Cloud Platform
Is there another way to manage your VMs? Yes, the introduction of the Cloudistics Cloud Platform has an innovative approach – non-clustered (or clusterless) federated design.The clusterless federation of the Cloudistics Cloud platform uses categories and tags to characterize computer nodes, migration zones, and storage groups (or blocks). With these benefits: ⦁ Node Limits Are A Thing of the Past. ⦁ Locking limitations are removed. ⦁ Flexibility is Enhanced. ⦁ Ladders of Latency are Removed. ⦁

This paper is written in the context of modern virtualized infrastructures, such as VMware or Nutanix. In such systems, a hypervisor runs on each compute node creating multiple virtual machines (VMs) per compute node. A guest OS runs inside each VM.

Data associated with each VM is stored in one or more virtual disks (vDisks). A virtual disk appears like a local disk, but can be mapped to physical storage in many ways as we will discuss.

Virtualized infrastructures use clustering to provide for non-disruptive VM migration between compute nodes, for load balancing across the nodes, for sharing storage, and for high availability and failover. Clustering is well known and has been used to build
computer systems for a long time. However, in the context of virtualized infrastructures, clustering has a number of significant limitations. Specifically, as we explain below, clusters limit scalability, decrease resource efficiency, hurt performance, reduce flexibility and impair manageability.

In this paper, we will present an innovative alternative architecture that does not have these limitations of clustering. We call our new approach clusterless federation and it is the approach used in the Cloudistics platform.

The rest of this paper is organized as follows. In Section 2, we describe the limitations of clustering and in Section 3, we drive the point home by using the specific example of VMware; other virtualized systems are similar. In Section 4, we present the clusterless federated approach and show how it avoids the limitations of clustering. We summarize in Section 5.

Scale Computing’s award winning HC3 solution has long been a leader in the hyperconverged infrastructure space. Now targeting even higher performing workloads, Scale Computing is announcing HyperCore-Direct, the first hyperconverged solution to provide software defined block storage utilizing NVMe over fabrics at near bare-metal performance. In this whitepaper, we will showcase the performance of a Scale HyperCore-Direct cluster which has been equipped with Intel P3700 NVMe drives, as well as a single-node HyperCore-Direct system with Intel Optane P4800X NVMe drives. Various workloads have been tested using off-the-shelf Linux and Windows virtual machine instances. The results show that HyperCore-Direct’s new NVMe optimized version of SCRIBE, the same software-defined- storage powering every HC3 cluster in production today, is able to offer the lowest latency per IO delivered to virtual machines.

How to Build a SANless SQL Server Failover Cluster Instance in Google Cloud Platform
This white paper walks through the steps to build a two-node failover cluster between two instances in the same region, but in different Zones, within the Google Cloud Platform (GCP)
If you are going to host SQL Server on the Google Cloud Platform (GCP) you will want to make sure it is highly available with a SQL Failover Cluster. One of the best and most economical ways to do that is to build a SQL Server Failover Cluster Instance (FCI). In this guide, we will walk through the steps to build a two-node failover cluster between two instances in the same region, but in different Zones, within the GCP.

If you’re here to gather some of the best practices surrounding vSphere, you’ve come to the right place! Mastering vSphere: Best Practices, Optimizing Configurations & More, the free eBook authored by me, Ryan Birk, is the product of many years working with vSphere as well as teaching others in a professional capacity. In my extensive career as a VMware consultant and teacher (I’m a VMware Certified Instructor) I have worked with people of all competence levels and been asked hundreds - if not thousands - of questions on vSphere. I was approached to write this eBook to put that experience to use to help people currently working with vSphere step up their game and reach that next level. As such, this eBook assumes readers already have a basic understanding of vSphere and will cover the best practices for four key aspects of any vSphere environment.

The best practices covered here will focus largely on management and configuration solutions so should remain relevant for quite some time. However, with that said, things are constantly changing in IT, so I would always recommend obtaining the most up-to-date information from VMware KBs and official documentation especially regarding specific versions of tools and software updates. This eBook is divided into several sections, and although I would advise reading the whole eBook as most elements relate to others, you might want to just focus on a certain area you’re having trouble with. If so, jump to the section you want read about.

Before we begin, I want to note that in a VMware environment, it’s always best to try to keep things simple. Far too often I have seen environments be thrown off the tracks by trying to do too much at once. I try to live by the mentality of “keeping your environment boring” – in other words, keeping your host configurations the same, storage configurations the same and network configurations the same. I don’t mean duplicate IP addresses, but the hosts need identical port groups, access to the same storage networks, etc. Consistency is the name of the game and is key to solving unexpected problems down the line. Furthermore, it enables smooth scalability - when you move from a single host configuration to a cluster configuration, having the same configurations will make live migrations and high availability far easier to configure without having to significantly re-work the entire infrastructure. Now the scene has been set, let’s get started!
