If you are experiencing storage performance issues, and if you have greater than 30 Datastores in an ESXi cluster, then this most likely is the cause of your storage performance issues, even if you have a high performing all-flash array and a high speed storage network. First we start with…
VirtuCache
London, UK. January 20,2023. AXA is a large multinational insurance company. AXA’s IT department in London deployed VirtuCache to improve the performance of their newly deployed Instant Clone based Horizon VDI deployment. They use various Netapp All Flash Arrays as primary storage. They were specifically looking to eliminate VDI boot…
Columbia Memorial Hospital (CMH) is a hospital on the Columbia river in NW Oregon. This project was a combination of Virtunet’s professional services to virtualize CMH’s CPSI EMR system and deploying Virtunet’s VirtuCache software to improve the storage performance of CMH’s VMware infrastructure. Needing a Hardware Refresh CMH was running…
VM snapshot is a very commonly used feature in the VMware vSphere environment. A VM snapshot preserves the state and data of a VM at a particular point in time. This includes the VM powered state, along with all the data including disks, memory and virtual devices. This makes the…
SYNOLOGY: CHEAP AND VMWARE READY Synology storage arrays have a few things going for them, they are one of the most reasonably priced storage arrays on the market that are also certified as ‘VMware Ready’ by VMware. HIGH LATENCIES IN SYNOLOGY WHEN CONNECTED TO VMWARE One issue with these appliances…
Beefing up Buffer Cache size in Oracle Database alone may not solve all your slow database issues. If your Oracle Database runs in a VMware VM and it has performance issues due to heavy insert and/or update load, the root cause of which is slow storage, then our host side…
February 18, 2022: United Arab Emirates. Virtunet Systems develops VirtuCache software. VirtuCache improves the storage performance of VMware VMs by caching all VM data (read and write operations) to in-host SSD or RAM. We deployed VirtuCache software at the Al Futtaim Group to improve the storage performance of their Dell…
One advantage that Hyper-converged infrastructure(HCI) has over SAN infrastructure is that HCI has put high speed storage back in the hosts. This is also true for Host Side Caching software. However, unlike HCI, host side caching retains the flexibility that SAN infrastructure has over HCI, of being able to do…
Even if you have a fast array and storage network, and you are still experiencing high storage latencies for your high throughput VMs, it might be because of choked Queue Depths at the VM and virtual LUN device in the host. This problem will happen only if a few VMs…
If your SQL Server runs in a VMware VM and it has performance issues, the root cause of which is slow storage, then our host side caching software for VMware, called VirtuCache, will be able to fix this problem. This post explains how VirtuCache does this by explaining the read…
