synology iscsi target masking

As for block vs. file, it really depends on the capabilities of your shared storage. DS412+ LUN Masking. Normally, I don’t like to double-up Management and VMotion on one port, but with only 4 ethernet ports on the hosts, we’re a bit limited in our options. it looks like your average transfer speed is 30mb/s per nic. In this example, I chose not to enable CHAP. Join the Community and share your feedback!

I’ve also heard that Thin Provisioning must be enabled as well, but I was not able to replicate it. The specific network design will be dictated by your environment and requirements.” I was wondering why that was needed when you had 1 of the 4 Synology nics already on the administrative subnet. Sorry, your blog cannot share posts by email. Very informative post.

Management Network 192.168.0.7 Now we’re going to create our LUNs.

The process is completely wizard driven and requires only a few inputs. I honestly thought this had to be 10.10.10.28 to be reachable from the Public network. Update:  Looking for NFS instead of iSCSI? Now, let’s jump over to one of our hosts and set up the networking and iSCSI software adapter. For this exercise, we’re using the VMware Infrastructure Client because I haven’t completed the build yet, so I don’t have a vCenter Server to connect a web browser to. That address is not related to the configuration, but was only being used as a convenience. Choosing a RAID 10 gives me 6TB (stripe + mirror) and higher performances with WRITEs.

The iSCSI initiator could not establish a . If you have 4 iSCSI connections, all on separate switches, all on different subnets, all on different vlans (which is the ideal scenario) and you allow multiple connections on your LUNS, and you configure round robin correctly on the host.

Thanks! At least I hope that’s it. I also have setup Round-Robin for 2 NICs. If you use CHAP, you’ll also want to configure it here (globally) or on the individual targets. From the main Synology NAS Desktop the Start > iSCSI Manager is the utility to manage the Synology DS620slim iSCSI targets. Your adapters should have opposite configurations. Ask a question or start a discussion now.

I was running at 1515+ with four nics active, and four nics for iscsi on ESXi Host. I did briefly come across a VAAI enabling driver for vmware for NFS, although I’ve not explored that yet. The very last thing we need to do is to enable Round Robin on our LUN. Do IP addresses of each iSCSI NICs should be in a different subnets? we are experiencing the same issue. Do I need to configure SYNOLOGY to run “Round-Robin” ? 3 ports for iSCSI storage. Performance is pretty bad as expected. I’ll read up more on VAAI. Please type your message and try again. I think I figured it out. My other NIC (vmnic1) is showing the discoverable network to be 10.10.30.10 – 10.10.30.11. these are the two IPs I am using on the synology on two diferent interfaces. Come and join us at Synology Community. Always open to constructive feedback and new challenges. Which of the following retains the information it's storing when the system power is turned off? You’ll see that the Hardware Acceleration state of your LUNs is “Supported”. Both the hosts and the synology are on the same subnet/LAN.

For MS ISCSI initiator its in the general tab where it says Initiator Node Name or easier - first logon to the target - then you can see it in Celerra Manager as connected hosts and cut&paste.

#1 You mentioned joining the storage network with the normal network, so you could access it administratively. This will prevent stray connections from unwanted hosts (or attackers). You’ll notice that only the top option is available. I’m trying out using the Synology as a datastore to run a couple of the VM’s. Then I kept digging and noticed that there was an error message when scanning: Login to iSCSI target iqn.2000-01.com.synology:dcpcsbhqx-n0001.target-1.asigradata on vmhba35 @ vmk1 failed. – No, the two switches in this exercise are linked to permit management of the storage network. This would lead me to believe that I could team both NICs on the same card. I am using a X520-DA2 SFP+ 10Gbe card in server and I am direct attaching to my synology using SFP+ twinax cables. It should be based on IP address and iSCSI initiator node names. After coming back on, the ESXi hosts had some trouble figuring out who had what VM, but for the most part, alot of VMs never even shut down. ; Select a LUN type: File-Level iSCSI allows the creation of Targets on existing storage volumes, so that storage may be shared between the two storage systems. While not exactly a powerhouse in terms of speed and reliability, this entry-level virtualization platform should serve to introduce them into the world of virtual servers, drastically reduce rackspace and power consumption, provide the flexibility they need to recover quickly from server hardware outages, and allow them to more easily migrate off of their aging server hardware and operating systems all without breaking the bank.
