Recently we had to troubleshoot rather high storage latency at a customer site. The environment consists of Hyper-V hosts connecting to 3PAR arrays via iSCSI. 3PAR arrays are all-flash arrays (AFA). I know such problems in vSphere environments too. There higher storage latency can be caused by delayed acknowledgement (DelAck). Read more about this issue and how to configure DelAck on vSphere ESXi hosts here. […]

This is a rather short post for a checklist respectively a step-list of things you should know/do to create certificates for VMware products like VMware View. The steps in this post should work for Windows 2008 and later. Furthermore you can use Step 1 and 2 for other products next to VMware View like vSphere. If you don’t have a Windows CA but want to […]
The list does not claim to be comprehensive. Use this information at own risk! User or device CALs Take user CALs when user uses more than one device to access the desktop. Take device CALs when there are more or equal devices than users. Microsoft licenses the physical person (named user) NOT an Active Directory-User! RDS CALs and VDA licenses VDA license includes the license for […]
Installation and how to use: Install the client by adding the feature “nfs client for windows” – straight forward … no reboot required use nftadmin to configure the client, if necessary use mount to map shares use umount to remote mount points Example mount \\nas-device\nas\share u: could be interesting: -o mtype=soft|hard hard: in case the nfs-server goes offline, the nfs client for windows will try to reconnect until the server […]
