Reading Time: 4 minutes Data Domain (or Power Protect if you prefer the new term) needs some free available space to manage its filesystem and all the mtree(s). By default there is a critical alert if the used space exeed 90% of the total space. The name of the alert is “SpaceExceedsCriticalThreshold” and cannot be changed from the GUI.

Reading Time: 3 minutes The upgrade procedure for DellEMC PowerStore X from version 2.0 to version 2.1 is a little tricky. The Dell EMC PowerStore Software Upgrade Guide explains the steps, but still there are some issue that you should mange. Because you have also to upgrade the ESXi from 6.7 to 7.0, but before this, you need also to resize the VMFS datastore.

Reading Time: 2 minutes If you try to upgrade the PowerStore OS and you get this error message: Prestage failed on appliance XXXX with the following message: The system encountered unexpected backend errors. Please contact support. (0xE04030010001) Then you may don’t need to contact the support, because the solution could be easy.

Reading Time: 3 minutes DellEMC PowerStore is the new product line that will replace the old Equallogic/SC/VNX/Unity series. It’s a nice product with a mix of the features of all those prevuious products and a new modern design both in the hardware and the software parts. From VMware vSphere point of view it can be access as a block level storage with iSCSI and/or FC protocols, but it has also a native vVols implementation and, for example, in the PowerStoreX model it’s the default way to access at the storage resources.

Reading Time: 4 minutes Trusted platform module (TPM) is a hardware, designed to securely store information such as crendential or measurements. TPM 2.0 is supported on all 13 th generation and 14 th generation Dell EMC PowerEdge servers including the latest AMD servers. Note that is not enabled by default. TPM 2.0 is enabled and supported with VMware vSphere 6.7 releases. ESXi 6.7 introduced the “Host Attestation” feature using which the validation of boot process can be reported to vCenter dashboard.

Reading Time: 4 minutes If you have tried to apply the VMware vSphere 6.7 Update 3 patch on a DellEMC PowerEdge server, you may have some kind of performance issues. The vCenter become very slow and some basic operations, including vMotion are very very slow (also more than 100 times!).

Reading Time: 2 minutes The Dell Compellent storage is an interesting solution and, before the EMC acquisition, was the main storage product in Dell portfolio. Veeam Backup and Replication offers different type of primary storage integration to improve and offload the backup process using storage snapshots (and limiting VMware snapshots only for the time needed to take a storage snapshot).

Reading Time: 5 minutes The Dell Boot Optimized Storage Solution (BOSS) is a new option for the installation of the hypervisor part, in a virtualization enviroment, or more important in a hyper-converged infrastructure (HCI) host! The dual SD option was already present in all PowerEdge, also in previous generations, and was a good choice to separate the hypervisor from the disks or simple use diskless based solutions. And was a good option for vSphere ESXi when servers were only used as a compute nodes.

Reading Time: 5 minutes The Dell Technologies World 2019 event is finished and it’s time to make a recap of what’s happened. You can start watching the three general sessions, available online with also a full transcript. There are some really important informations not only about the products, but also about the vision. Also there are different interviews available to learn more.

Reading Time: 3 minutes The Dell(EMC) World event has been renamed last year in the Dell Technologies World Conference and has become a very very huge event and this year will be probably bigger than ever. Dell Technologies is the “umbrella” that includes all those companies: Dell, the new DellEMC, Pivotal, RSA, SecureWorks, VirtuStream, VMware.

Reading Time: 3 minutes VMware vSphere Update Manager (VUM) enables centralized, automated patch and version management for VMware vSphere and offers support for VMware ESXi hosts, virtual machines, and virtual appliances. For ESXi hosts it can manage both the update and the upgrade workflows, but can also be powerful for adding custom VIB package, like for example new drivers. Usually it takes the updated files from the VMware repository, but you can also add custom repositories (or depots).

Reading Time: 3 minutes Dell EMC has probably a storage portfolio too rich and with some overlaps, due to the EMC acquisition, and I was quite sure that the Dell PowerVault MD storage series was destined for early obsolescence to be replaced by the Compellent series. But obviously, I was wrong. Dell EMC announced a new PowerVault line: Dell EMC PowerVault ME4. As the previous PowerVault MD series, also the new PowerVault ME4 (very strange name) is targeted for the specific SMB market.
