Synology released DSM 5.1-5021 update as well as Cloud Station 3.1-3320 today. This update includes all the updates since 5.1-5004 as well as fixes for a number of vulnerabilities in PHP, OpenVPN, and other security improvements. DSM 5.1-5004 also improves Amazon S3 backup stability along with a number of other fixes and improvements.
If you use the VMware ESXi 5 ISO image and try to install it on an Intel NUC you’ll receive the following error during the install.
No Network Adapters
No network adapters were detected. Either no network adapters are physically connected to the system, or a suitable driver could not be located. A third party driver my be required.
Ensure that there is at least one network adapter physically connected to the system before attempting installation. If the problem persists, consult the VMware Knowledge Base.
The “No Network Adapters” on the Intel NUC error message during the ESXi install is because VMware removed a number of drivers (non-enterprise drivers) from their ESXi 5.x image and in order to use the Intel NUC as an ESXi host you need to create a customized ESXi image with the NIC drivers added to the image.
In the recent DSM update (5.1), Synology added VMware VAAI support for NFS volumes using two primitives which are Full File Clone and Reserve Space. What do these VAAI primitives offer?
- Full File Clone enables virtual disks to be cloned by the NAS albeit while the machine is powered off.
- Reserve Space allows you can create a thick VMDK file. However Reserve Space does not off-load the work to the array. The benefit of thick VMDKs is that many use eager-zero for high I/O performance needs.
On the Synology side of things you just need to update to DSM 5.1, but in order to take advantage of VAAI you still need to install the VIB plugin on your ESXi 5.5 hosts.
I typically use G.Skill memory in my NUC’s as I’ve had great luck with the brand in my desktop and laptop for years. However G.Skill has been increasing in price which made me look around for alternatives and came across Crucial DDR3 204-pin memory for less money, but days after I purchased it they too went up in price. However they are now back on sale and cost about $50 less then the G.Skill memory I have been using in my first two NUC’s.
I’ve been using the Crucial memory now for the last several months without any problems and even though they are rated at a lower voltage I can’t say I really see any difference in power savings or consumption compared to the G.Skill 1.5V. If you’re looking to upgrade now might be a good time to take advantage of the sale price.
A little while ago I posted several ways to improve the security on your Synology NAS and was recently asked about how to install CrashPlan on a Synology NAS. Synology doesn’t have it’s own pre-built package available, but luckily PC Load Letter from the Synology community has stepped up and made a Synology package that works beautifully – the only downside is his instructions are a bit dated and I found harder than they needed to be.
If you don’t already have a CrashPlan account, go ahead and sign up now.
Over the past weekend I was working on a whitebox ESXi host and wanted to upgrade it to ESXi 5.5 Update 2 from an older version of ESXi 5.1 using a realtek R8168 network card. While I could have performed an in place upgrade, such as via command line, a clean install was preferred. However, VMware has removed a number of NIC drivers from ESXi 5.x and trying to install with the base ESXi image would result in a “No Network Adapters” error during install.
In order to do a clean install you have to re-add the Realtek R8168 NIC drivers back into the ESXi 5.5 image, otherwise a NIC will not be found and thus ESXi will not install. These are the steps to easily re-add the Realtek R8168 drivers into ESXi 5.5 ISO by making a custom ESXi 5.5 image.
