Emre Kurnaz's IT Diary

I have been using Isilon simulator for a long time to test some features and prepare myself to some projects. Knowing that this is a home environment, I am also performing patch installations when I have time. Lets first power on the Powerscale nodes on my Vmware Workstation. We will need to wait some time for all nodes to totally up and running. Lets check if we are able to login from the cli and run "isi status" to check the cluster status. Next, we will need to download the Rollup Patch from the Dell Technologies Support page. After downloading we will need to extract the file. You will see that the contents of the file similar to below; here we will need to upload the file with the pkg extension to the /ifs/data/Isilon_Support/ .  I am using FileZilla to perform the upload I can verify that the file is there. Here we are ready to Perform  the code upgrade. This part really important since we are here only performing the code upgrade, in a real work scenario, you will nee...

One of the most struggling parts of administrating a huge NAS system like Isilon/Powerscale is Antivirus management. ICAP is the most used protocol for Antivirus scanning, which is basically, NAS is sending the file to the Antivirus server and wait for the file analysis and quarantine/truncate etc if needed. Most of the NAS admins can complain how this approach is not that much effective with the aspect of resource utilization and performance of antivirus scanning. CAVA is currently available on Powerscale OneFS versions 9.1 and later, and supports SMB protocol only. What it does is sharing the IFS filesystem only to CAVA servers over a restricted zone and IP Pool and relies on the filesystem auditing.  Whenever a file access is requested, the audit is sent to the CAVA/CEE Agent on the Antivirus server for him to identify what filepath needs to be scanned, and access the file path over CHECK$ share and performs the scan. To have a successful implementation of CAVA, please make sure...
