VMware vSAN at home and crossflashing Dell Perc H200

I will not conceal that this is my second attempt to vSAN at home Lab. The first ended in total failure which can be summarized by the word “too short queue depth.” The second approach is more solidly prepared and technology in the meantime changed. Instead the first version of vSAN now we have vSAN 6.2 that has been heavily redesigned in terms of performance and generated load on the device. In the meantime born faster SSDs based on 3D-NAND and a little easier on the controller with appropriately long queue commands (queue depth). In my Lab I have only one server (for now), I decided to build vSAN based on Dell PERC H200 controller, disk Samsung Evo 840 120GB and HGST 7K1000 disk. Controller H200 is the cheapest controller that can be bought on the open market (Ebay), even though it was out of the VMware vSAN HCL is still well suited to this task (queue depth a length of 600, current recommendation is not less than 256 and preferably 1000 or higher). Disk Samsung 840 Evo does not have to represent, class of its own, I bought a 120GB (recommendation is 10% SSD in the total pool, but it depends on how much we have hot data). HGST drives K71000 is a quick drives to laptops with 32MB cache (I have a two and perfectly suited as a local datastore in ESXi), are quiet and do not heat up too much. It remains to answer the question: why? Of course, in order to improve performance as shown below!

Nested KVM in VMware ESXi

Last check very intesively all type of Cloud solutions available on Open Source license (such as Proxmox, oVirt and CloudStack). All they mainly use a free hypervisor that is KVM. Of course, there is no question about that every now and then to put the physical machine with KVM since all have virtualized with VMware vSphere. In this article I will show how to prepare a nested KVM server (based on CentOS 7) and working under the control of VMware ESXi (similar configuration will work with VMware Workstation).

EMC Unity VSA – accessible for all for free with support for Veeam Backup.

The fussion of Dell and EMC became a reality. The consequence of this is the exchange of entire product lines, disappears VNX brand and debut Unity (here you can read more about this). Fortunately, the approach of the new company for Open Source solutions and distribute their software in the full version has not changed. I not so long ago described the installation of EMC vVNX (and tests VVOL) and already we have a vVNX successor, EMC Unity VSA. And this is the full version (not beta). This means that we can downloaded it from support.emc.com (ova) and that will be available upgrade files for this solution. Licensing not changed, free version for no production usage supports 4T RAW and all possible functions (including FastVP). Installation and configuration is very much like the installation of the previous version (vVNX) so I will not describe it exactly, I will focus more on the differences.

Installing a Ceph Jewel cluster on Ubuntu LTS 16 using ZFS

Software-defined storage (SDS) is developed at a dizzying pace. At the moment, we have to choose from a whole bunch of solutions, eg. VMware vSAN, EMC ScaleIO (which is based on Ceph), GlusterFS, XtreemFS and at the end, Ceph. Unfortunately, to date, none of these solutions natively supports features such as deduplication (only vSAN 6.2 supports deduplication and compression). In this article I will show you how to install, on three nodes, Ceph Jewel cluster (the latest stable) based on disks (OSD) formatted with ZFS. The ZFS source are Solaris OS (and Sun Microsystems, now Oracle), now it is fully ported to a Linux system. For the first time also received the full support on Ubuntu LTS 16. The purpose of this exercise is to test deduplication on SDS (which ZFS supports) and check whether it is possible. But remember, Ceph officially does not support OSD on ZFS.

Veeam Agent for Linux – backup goes back to the clouds!

The Veeam company has just started testing its new, completely free tool, which is Veeam Agent for Linux (currently in beta). Who previously registered to the testing program can today download the solution and check its functionality. The basic question is, who will benefit from this tool? All those who use public clouds and running there own servers, very quickly collide with the basic problem which is the lack of backup. Often, this option is available (additional fee), which, however, usually comes down to the snapshoting of the virtual machine. There is no possibility to regular backups and sending them to own DC, and if this possibility exists it is a very expensive option. Veeam comes up against this problem by providing an agent, which in the future will be fully integrated with Veeam Backup & Recovery. This agent will be installed locally on the machine and will perform a full file backup (this is not a traditional snapshot of the entire virtual machine) via the network (eg.VPN).

Configure Trend Micro Deep Security with VMware NSX for vShield Endpoint

VMware NSX achieved the status of GA and now each holder of a vCenter Standard license can download and install VMware NSX for vShield Endpoint. Generally, this is a very good move on that waiting a lot of people. At this point, it is now possible to migrate from VMware vShield Manager to VMware NSX in the vCenter 6 environment (particularly for holders of vCloud Suite 6 license). It also means the ability to migrate Trend Micro Deep Security from version 9.5 to version 9.6. But before you cast in to perform the upgrade as described here, think about it twice and thought to everything thoroughly. License NSX for vShield Endpoint is a very stripped down, basically has only two functions. Agentless antivirus (AV offloading) and Integrity Monitoring. This means that if you have a full license for all Deep Security modules you must use the agent in combination mode to use them all.
