Guys, quick question.. I have a synology DS214 with 2x2TB regular HDD drives. I’m presenting iSCSI and NFS to my ESXi host. I was doing some testing and cloning a server over iSCSI took 15 minutes but over NFS only took 6 minutes. Is that normal? is NFS faster? lighter? I did notice that the iSCSI process took more resource on the synolgy than the nfs process. #notastorageexpert

The DS214+ does not support VAAI or other storage acceleration for virtualization. So I doubt the plain DS214 would. Synology VAAI support is limited to iSCSI. From experience it makes VM migration, snapshots, etc perform much better than NFS. I have never saw or did a comparison between VAAI vs iSCSI vs NFS. I know NFS iops is superior to plain iSCSI, but the gap has been significantly closed in the last few DSM 5.0 updates.

I have the VAAI vib installed on my ESX hosts and ISCSI works great (having in consideration the 1G link and the 4xWD30EFRX RAID5 array...

How would i come to know from Netscaler, when (time) my service went in down state

Thanks @User, since I don't have VAAI the I think that you are saying that NFS could perform better?

Yes @User

I would say that NFS IOPS are generally not superior to iSCSI, but because of thin provisioning and caching, it can equal or sometime outperform iSCSI because of the thin provisioning aspect. I've done extensive head-to-head comparisons of iSCSI vs. NFS. On modern servers, I will acknowledge that NFS can equal or sometimes exceed iSCSi performance, but so much depends on the whole setup.

@User has joined the channel

@User I also prefer iSCSI because it's faster, but in this case, iSCSI is slower because there is no hardware support for VAAI in that small NAS that @User has.

Makes total sense! 👍

It's great when two geeks agree on the same topic 😂

Well I have thin provisioning enable on my iSCSI LUNs, or at least it says it is enabled

What OS is it running internally?

@User: any update on SM & the case? Wondering about alignment. I've got 8x NUC, but 4 is already sold, so I could to SM with 128GB and run 4x Xen on Xen, cheaper & better

Cool

Only doubt is how to slice 1x 2TB SSD into 4x 500GB, one for each student @User on Xen on Xen that is

You can just create one 2 TB SR and create separate VDIs for each of the VMs.

Okay, maybe one XenServer on bare metal with 2TB, the create 4 new XenServer VMs with 509GB each

@User: the idea is using one powerful srv instead of 4 NUCs

What you're saying is that you'd need an external storage option, right? Could you designate one NUC just as a file server and load the storage onto it?

No too slow, need 2 be local. Thinking about running xen on xen

That may work, yes. That's how Citrix runs some of its classes.

@User Any plans to offer a "virtual online" master class?

that's a good idea @User I & students would save on travel, hotel, meeting room etc. Probably could do something like that at $997 for 3 days, what do you think?

@User You would teach the exact same content as the "in person" class?

@User You might even make it 3 non consecutive days, eg, Mon, Weds & Fri.

@User I would sign up!

@User awesome, but would your manager pay for it 😉

and what about hardware? bring you're own NUC or similar with 32GB
