It doesn't matter how small or how big the amount is, all donations help! Two of our suggestions, and non-profits we personally support are, and of course helping them would be appreciated by us:. Introduction to the book. Introduction to the book When talking about virtualization and the underlying infrastructure that it runs on, one component that always comes up in conversation is storage.

Virtual SAN 6. Writing for vSphere administrators, architects, and consultants, Cormac Hogan and Duncan Epping explain what Virtual SAN is, how it has evolved, what it now offers, and how to gain maximum value from it. They offer expert insight into preparation, installation, configuration, policies, provisioning, clusters, and more. Search this site. PDF Online. A Memory A Keepsake PDF. All-flash Virtual SAN configuration brings improved, highly predictable and uniform performance regardless of workload as compared to hybrid configurations.

More information can be found regarding these features in the space efficiency guidance document. In hybrid clusters which uses magnetic disks for the capacity layer and flash for the cache layer , the caching algorithm attempts to maximize both read and write performance. Multiple writes are coalesced and written sequentially if possible, again maximizing magnetic disk performance.

All-flash clusters have two types of flash: very fast and durable write cache, and more capacious and cost-effective capacity flash. Many more writes are held by the cache and written to the capacity layer only when needed, extending the life of the capacity flash tier.

Best practice: Ensure there is enough cache to meet the design requirements. Minimum number of ESXi hosts required 6. More information can be found about this in the stretched cluster and two node guide. This is the same for all versions. While Virtual SAN fully supports 3-node configurations, they can behave differently than configurations with 4 or greater nodes.

In particular, in the event of a failure there is no way for Virtual SAN to rebuild components on another host in the cluster to tolerate another failure. Also with 3-node configurations, Virtual SAN does not have the ability to migrate all data from a node during maintenance.

Design decision: 4 node clusters allow for greater flexibility. Consider designing clusters with a minimum of 4 nodes where possible. For Virtual SAN 5. To run 64 nodes, certain advanced settings must be set. In version 5.

Of course, available compute resources also limit the number of virtual machines that can be deployed in practice. This consideration will be examined in detail later in this guide when some design and sizing examples are explored. Maximum number of virtual machines protected by vsphere HA In vsphere 5. Therefore, in a Virtual SAN cluster with vsphere HA enabled, if there were more than virtual machines, vsphere HA would not be able to protect them all.

This limit has been lifted in vsphere 6. Disks, disk group and flash device maximums Disk groups are management constructs created by combining locally attached storage devices. In hybrid configurations, a disk group will be a combination of a single flash-based device for caching and performance, and multiple magnetic disk devices for capacity.

The creation of a disk group on hybrid configurations requires the assignment of a single flash-based device and one or more magnetic disks. In all-flash configurations, a disk group will be a combination of flash devices that serve two purposes.

First, a single flash-based device for caching and performance, and second, there are multiple additional flash devices used for capacity. An additional step is required which specifically marks the flash devices destined for the capacity layer as capacity flash devices.

The creation of a disk group on all flash requires the assignment of a single flash-based device for caching tier-1 device and one or more additional flash devices for the capacity layer. Caution: Virtual SAN does not support the mixing of all-flash disk groups and hybrid disk groups in the same cluster. Mixing disk group types can lead to erratic performance. Capacity devices can be either magnetic disks for hybrid configurations or flash devices for all-flash configuration.

Flash cache devices are dedicated to an individual disk group: they cannot be shared with other disk groups, nor can they be shared for other uses. In hybrid configurations, there is a maximum of 7 magnetic disks per disk group for the capacity layer and there is a maximum of 1 flash device for cache per disk group. In all-flash configuration, there is a maximum of 7 flash devices per disk group for the flash capacity layer and there is a maximum of 1 flash device for cache per disk group.

Extrapolating these maximum values, there can be a total 35 devices for the capacity layer per ESXi host and a maximum of 5 devices either PCIe or SSD for the cache layer per host.

Each of these objects is comprised of a set of components, determined by capabilities placed in the VM Storage Policy. For example, if the virtual machine is deployed with a policy to tolerate one failure, then objects will be made up of two replica components. Storage Design and Implementation in vSphere 5. There has been many new features introduced in vSphere 5, I presented some of them, like the VMFS 5 which has been introduced in vSphere 5, in my blogpost here.

Learning all this with a book published by VMware press could be just easier…. And this shows the importance that VMware puts accent on good and quality published books. It's in available at Amazon. I also got a copy and I did a review of the book which you can read on this blog post here. And below a sample review from Amazon. Although this might be true in some cases the first thing the book tought me was that my perception was wrong. The book shows you how to optimize your day-to-day operations by taking advantage of what PowerCLI has to offer out of the box, but it also teaches you how to create your own functions.

Get more details here. Maximum vSphere — Eric Siebert, Rich Brambley and Simon Seagrave did a good job by writing this book which brings in some best how-to tips on managing, installing, administering or backing up of a VMware vSphere Infrastructure.

This is covering from all levels of skills Beginner,Intermediate and Experts. The day I received this book I couldn't find time to read it, but the day I started reading this book I couldn't find time for other activities. I am going to add more and more vsphere Under Development to my website […] based on the knowledge I am gaining from this book. I personally recommend to any folks trying to have a overall and performance insight of vsphere-4,4. Thanks to Eric Siebert and his team for getting this book out with most valuable information at the right time.

Skip to primary navigation Skip to main content Skip to primary sidebar Christmas is coming so Cormac and I figured we would do something special for everyone, after a long debate we decided to make the vSAN Essentials book available for free. There was a fundamental shift in how we collectively thought about how to operate and architect IT infrastructures when virtualization was introduced. As always, my brothers are being gracious in sharing their knowledge. Now another collective shift is happening all over again. View all posts by Cormac. Part of the VMware Press Technology series. Download them here. The reason is that most storage platform architectures were developed long before virtualization existed, and virtualization changed the way these shared storage platforms were used. The book however is still very relevant today, and of course we are considering doing an update of the content to either the latest release, or maybe even to an upcoming release. essential virtual san vsan 2nd edition pdf free download
