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 […]
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.
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 […]
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 […]
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…
One of the most misunderstood and powerful features in Rubrik is the concept of the SLA Domain. It controls everything from the frequency to backup windows, retention, replication (to another Rubrik cluster), archiving (to S3/NFS/Object etc), and it also acts as the policy to determine compliance. In Rubrik you don’t have the complexity of creating…
