SSDs deployed in CEPH OSD servers, whether for caching / journaling or primary storage, are not very effective from a performance point of view. The problem lies not in the SSDs, but because they are deployed at a point in the IO path that is downstream (in relation to VMs…
VirtuCache
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…
VirtuCache is software that improves the performance of Dell Compellent appliances without requiring you to upgrade the appliance or the SAN network. The performance improvement you will get from your Compellent appliance will rival an upgrade to an all-flash array. Compellent appliances were the workhorses of the enterprise storage market…
CEPH is a popular open source storage software. However its write latencies are high. VirtuCache caches CEPH volumes to in-host SSDs and by doing so reduces VM level latencies considerably.
VirtuCache is software that improves the performance of Equallogic appliances without requiring you to upgrade the appliance or the SAN network. The performance improvement you will get from your Equallogic appliance will rival an upgrade to an all-flash array. Equallogic appliances were the workhorses of the enterprise storage market a…
