What to Look for in Cloud Native Backup — StorageSwiss.com – The Home of Storage Switzerland

Users and software vendors realize the importance of protecting cloud-native applications. While cloud providers generally do an excellent job of protecting applications from a disaster they don’t provide easy access to tools to provide point-in-time backups which are necessary to protect against user error, cyber-attack and application bugs. It is important to acknowledge that protecting […]

How to monitor VM snapshot usage on Nutanix Acropolis — VMwaremine – Artur Krzywdzinski | Nutanix

Virtual Machine snapshot is an excellent feature which helps quickly rollback changes if something goes wrong. However, many users or Admins are using snapshots as “backups”. Basically, they create a snapshot and forget to… The post How to monitor VM snapshot usage on Nutanix Acropolis appeared first on VMwaremine – Artur Krzywdzinski | Nutanix.

Nutanix releases AOS 5.9 with another leap of new features

Nutanix releases its new AOS 5.9 software update with new features to help customers build more resilience, secure enterprise cloud.

Here is a list of some of the new feature;

1. Support for VMware vSphere 6.7 which was much anticipated is now supported with foundation 4.2
2. Support for NVIDIA Tesla V100 16GB GPU with AHV version 20170830.171 and later.
3. RDMA support for NX G6 models with two RDMA-supported NICs. RDMA allows low latency data transfer to improve network latency and lower CPU utilization.
4. Prism Central can be used to manage Nutanix Guest Tools allowing bulk operations.
5. RHEL in-guest clustering support using Nutanix Volumes (ABS).
6. Software encryption now becomes on-the-fly, enable on cluster or container with or without existing data.
7. Switch between native or external KMS for encryption is now supported.
8. Now you can build Metro Hyper-V 2016 clusters for active-active data center and site high-availibility.
9. Best of all now cluster can be configured as rack aware to provide resiliency for full rack or TOR switch failure.
10. Can have asynchronous and near-synchronous schedule in same protection domain.
11. Now near-synchronous is application-consistent and supports third-party backup solution which depends on protection domains.
12. One time snapshot support for near-sync, which will help you reduce re-sync times.
13. The setting view has been changed now, on clicking on settings wheel will have all the options available on left of console.

In this release Nutanix also release Karbon as tech preview to deploy and manage Kubernetes clusters using Linux containers using simple web console.

As Prism Central is now independent to AOS release Nutanix also release Prism Central 5.9 with new features.

1. Supporting bulk operations like install, manage and upgrade of NGT on multiple VMs.
2. The setting view has been changed now, on clicking on settings wheel will have all the options available on left of console.
3. What-if scenarios now can analyse removal of any part and impact on running workload.
4. Nutanix Calm now supports Microsoft Azure along with AWS, GCP and VMware.
5. Can use PowerShell for Windows VMs automation directly removing any need for separate VM as Powershell Gateway.
6. Calm users can now save tasks (custom scripts) in task library to be used in other blueprints.

More to be found on Nutanix Portal and Happy Prism 1-Click.

NOTE: AOS 5.9 is Short Term Support release and be aware of support terms of STS and LTS and always read release notes before upgrading any software releases.

 

 

HCI Performance testing made easy (Part 1) — n0derunner

In this short series I will describe how to perform performance an resiliency tests on a HCI cluster using X-ray. X-Ray can do the following for the performance tester. Model IO workloads using standard fio format Create VMs based on user-specified criteria (CPUs, Memory, Number & Size of disks) Provision the VMs to a HCI […]

Today we will use the simplest workload that X-Ray provides, the “Four Corners” Benchmark. This is the classic storage benchmark of Random Read/Write and Sequential Read/Write. Most people understand that this workload tells us very little about how the storage will behave under real workloads, but most people also want to know “How Fast” will […]

HCI Performance testing made easy (Part 3) — n0derunner

Creating a HCI benchmark to simulate multi-tennent workloads HCI deployments are typically multi-tennant and often different nodes will support different types of workloads. It is very common to have large resource-hungry databases separated across nodes using anti-affinity rules. As with traditional storage, applications are writing to a shared storage environment which is necessary to […]

HCI Performance testing made easy (Part 4) — n0derunner

What happens when power is lost to all nodes of a HCI Cluster? Ever wondered what happens when all power is simultaneously lost on a HCI cluster? One of the core principles of cloud design is that components are expected to fail, but the cluster as a whole should stay “up”. We wanted to…
