The main advantage that hyper-converged infrastructure(HCI) has over traditional SAN based infrastructure is that HCI has put high speed storage back in the compute nodes. This is also true for Host Side Caching software, with the added benefit that host side caching maintains the flexibility that SAN based infrastructure always had…
Competitive Differentiators
Storage IO path in VSAN and VirtuCache is similar to a large extent since both service storage IO from in-VMware host media. Though with VirtuCache, storage latency is lower than with VSAN for four reasons: Reads are almost always serviced from local cache media in VirtuCache. In VSAN there is…
VMware has discontinued VFRC in ESXi 7.x 0 Despite the end-of-life for VFRC, if you still want to review the differences between VFRC and VirtuCache, below are the four most important ones. We cache reads (‘Write-Through’ Caching) and writes (‘Write-Back’ Caching), VMware’s VFRC caches only reads. We improve the performance…
The big difference between the two is that VSA can cache a maximum of only 2GB of reads from the Master VM on a per host basis.1,2 VirtuCache caches reads and writes from all server & desktop VMs, and it can cache to TBs of in-host SSD/RAM, with the goal of…
The biggest differences are: Virtunet’s VirtuCache accelerates reads and writes. Infinio Accelerator accelerates only reads. Infinio doesn’t support Linked Clones or Instant Clones, hence VDI is not supported. We support all VDI features in VMware Horizon and Citrix. With us, you can apply caching policy at the datastore and/or VM level versus…
Both cache ‘hot’ data to in-host RAM, but the differences between Citrix MCS Storage Optimization and VirtuCache are many. The top three are: – MCSIO works only for non-persistent Xenapp / Xendesktop VMs.1 VirtuCache works for all VMs on the ESXi host; – Citrix MCSIO can cache only VM writes…
PernixData FVP was end-of-lifed in 2019. For the most part, both our GUI and workflows are similar. This article compares, with screenshots, steps to install and configure VirtuCache and PernixData FVP. The only differences between us and Pernix stem from the fact that we leverage VMware’s own capability in the…
Update as of August 2020 – Datrium has recently been acquired by VMware and as a result, has announced the end-of-life for their DVX product line. Original post follows. In our first article, we explained the differences between our host side caching software (VirtuCache) and Datrium’s (DVX DiESL). To summarize…
PernixData FVP was end-of-lifed in 2019. More similar than different Both us and PernixData differentiate from rest of the host side caching vendors in similar ways – that we are kernel-mode software; both of us cache reads and writes; have data protection strategies to prevent data loss in case of…
Update as of August 2020 – Datrium has recently been acquired by VMware and as a result, has announced the end-of-life for their DVX product line. Original post follows. Both Datrium and us differentiate from the rest of the storage appliance vendors in that both of us cache data to…
