#NEXENTASTOR INSTALL TO USB DRIVE UPGRADE#
I’m Pleased to report that the 8Gb RAM upgrade has resolved all the problems with navigating the UI, and should also yield further I/O performance as the Nexentastor software uses the extra RAM as extra cache (ARC) as well as the SSD (L2ARC) – there is a good explanation of that on this blog post. Users can directly install the distribution from the GRUB-powered boot prompt. Citrix XenServer and VMware images of NexentaStor are available for download from the project's home page. I am also booting the OS from a USB flash-drive – I had several 2Gb units but it wouldn’t install to them as they didn’t have quite enough space, so I’m using an 8Gb flash drive to hold the OS – this isn’t the most performant drive either so any swapping will be further impacted by the USB speed. I used the 250G drive that came with the N40L to install the NAS software. The project is distributed as a single CD-size ISO image that lets users to boot the operating system directly from a USB flash drive or CD disc. Due to a bug in the Ubuntu server installer, don’t add the pci passthrough card yet. Create new 64bit Ubuntu VM, 2 cpus, 8 gb ram, 1-20GB disk, at least 1 network adapter, and set to start automatically. I am using a 4GB USB drive attached to an internal USB port.

#NEXENTASTOR INSTALL TO USB DRIVE UPDATE#
I went for 8Gb as at some point I will probably re-run my experiments under ESXi and deploy this host as a part of my management cluster for the vTARDIS.cloud. All components 2 TB SAS III HGST Ultrastar 3.5' 7.2k (512e) 27 TFT monitor ASUS MG279Q (WQHD) (height adjustable) 2U Supermicro Chassis SC826BE1C-R920LPB 1 TB SAS III Seagate 3.5' 7.2k (512n) Broadcom. Install vsphere 5.1 update 1 on the new server. So, I bit the bullet and ordered 8Gb of RAM for the server, which is the maximum you can install – ironically this cost the same amount as I paid for the whole Microserver in the 1st place (after the cash-back deal) but that’s reflective of the fact it only has 2 memory slots so I had to opt for the more expensive 4Gb chips. The HP Micro server I am using shipped with 1Gb of RAM, and normally that would be fine for a file-server/NAS but I’m thinking that Nexentastor does a fair bit more and is based on OpenSolaris rather than a stripped down Linux or BSD the eval guide says 768Mb is enough for testing, 2Gb better 4Gb ideal so I was already pushing my luck with 1Gb for any real use. I have been trying to get my Nexentastor SSD/SATA hybrid NAS working this last week and I’ve found that the web UI grinds to a halt sometimes for me, I couldn’t find a UNIX ‘top’ equivalent quickly but the diagnostic reports that you can generate from the setup menu command line did indicate that it was short of RAM.
