System admin and engineer number will approach zero because once more stuff move to the cloud, the amount of work will also be reduced. The cloud vendors' favorite propaganda is the cloud will give sysadmins and engineers more time to focus on things more relevant to the business. I say BS...

I concur with 4saken here. The hypervisor is a commodity now and things are moving toward Automation, Cloud (private, public, hybrid), and Containerization technologies. VMware is scrambling to get their own Cloud service going, so as to be on the same sentence as Azure and AWS. 4saken is...

Check out the new article on GEA's new AIO - Napp-IT, OmniOS, ESXi virtual appliance. http://www.servethehome.com/omnios-napp-it-zfs-applianc-vmware-esxi-minutes/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+ServeTheHome+%28ServeTheHome.com%29

Thanks GEA! Really interesting how you use AIO, ZFS, and ESXi to handle high availability.

Awesome feedback, especially from the production point of view! Thanks! Thank you also for the hard drive feed back. I was going to get 3.5" 7200rpm SAS enterprise drives but they are way too expensive. From this and other feedbacks, I think SATA drive will do and will try the entry-level...

From some guy on the FreeNAS forum, FreeBSD 10 is re-doing their iSCSI implementation.

GEA, can you elaborate on the Napp-IT feature of "Monitoring"? What exactly does it do? That's the only add-on that I might need with Napp-IT. I now that it allows me to see those LED light for "pool, cap, disk, net, cpu, and job" What else does it do?

Solaris IS faster than BSD, period! :) From my real world application test and these benchmarks, OmniOS was ALWAYS faster in every way. I went with FreeNAS because I was having NFS disconnect issue with OmniOS using HP SmartArray p400 but now I finally got the M1015 in IT-Mode, so we'll see if...

Test re-done with OmniOS and Napp-IT Intel DC S3700 100GB as ZIL device partitioned to 3GB iSCSI, 50GB LU (volume based) Sync=Disabled http://imageshack.us/photo/my-images/855/p6sz.jpg/ Sync=Always http://imageshack.us/photo/my-images/850/wjox.jpg/ Sync=Standard...

Result of Intel DC S3700 100GB used as ZIL device under-provisioned to 8GB partition. Environment: ESXi 5.1, FreeNAS 9.1, 1Gbps Network, 50GB iSCSI target from FreeNAS mounted on Windows 2008 R2 VM. 4 x Raidz vdevs - each vdev has 3 10K rpm SAS disks Sync=Disabled...

Just got the Intel DC S3700 100GB for ZIL device! preliminary testing is really awesome. With NFS sync=standard, I get almost same performance (close to 97%) of sync=disabled! Do you under-provision the S3700 to 3GB for ZIL for endurance? ZIL only needs about 3GB on 1Gbps network...

My storage for the VMs is a ZFS box with M1015 so there is no write back cache. So, it looks like using iSCSI with ZFS (with sync=standard) is not safe then?

Thanks GEA, I know what NFS does. I am only interested in iSCSI on ZFS. What I want to know is, if I use iSCSI with ZFS (with sync=standard) and ESXi, am I safe? My client is a Windows 2008 R2 VM using Veeam backup/replication.

I read your reply several time and am still not clear. So, if I use iSCSI with default ZFS configuration of sync=standard, am I safe if I lose power? From the sound of it, it is NOT safe?

I have question about data security and safety with regards to NFS and iSCSI in default config of OmniOS (or any Solaris based OS) with regards to sync writes. Environment: ESXi and ZFS NFS vs iSCSI (COMSTAR) Sync = Standard No ZIL device With NFS: 1) sync=standard > data is safe if lose...
