Fibre is, well, neat but DAC is simpler with no issues of dirty fibre connectors, etc. Probably a little cheaper as well. I have redundant connections between the ESXi server and the NAS.<\/p>\n\n\n\n<p>The start up of the VMs seems a little faster to start but is a little hard to judge. A Windows Server 2022 VM using CrystalDiskMark showed the following results:<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"663\" height=\"482\" src=\"https:\/\/blog.pelleys.com\/wp-content\/uploads\/2022\/02\/Windows_Server_2022_Benchmark.jpg\" alt=\"\" class=\"wp-image-911\"\/><\/figure>\n\n\n\n<p>On the Synology NAS, here&#8217;s the results:<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1027\" height=\"127\" src=\"https:\/\/blog.pelleys.com\/wp-content\/uploads\/2022\/02\/RS1221Speed.jpg\" alt=\"\" class=\"wp-image-912\"\/><\/figure>\n\n\n\n<p>Note that these scores are in mega<strong>bytes<\/strong> per second, so we need to multiply by 8:<br>* Windows Server: 5,678.64 megabits per second<br>* Synology NAS: 5,388.8 megabits per second<br>Not bad with the overhead of a VM.<\/p>\n\n\n\n<p>Note that there is no switch involved. I have a direct connection between ESXi and the NAS. Eventually I may add a 10 GbE switch (likely a UniFi USW-Aggregation) and a 10 GbE card to the old DL360 Gen8.  I can still connect the DL360 to the iSCSI targets using 1 GbE. The DL360 is only for testing anyway.<br><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I&#8217;ve been running iSCSI between my DL380 Gen9 VMware ESXi 7.0.3 server and Synology RS1221+ NAS at 1GbE.
