Newbie (1/7)



  1. just FYI - this guide - the Chinese portion (mostly the .vmdk file ) allowed a perfect migration from 6.1 (1.02b2) to a 6.2 with a LSI passthrough created the vmdk for the new synoboot.img (renamed synoboot62.img, and synoboot62.vmdk respectivly) uploaded to datastore removed old synoboot file HDD from config switched to bios booting added new Synboot making sure to use SATA/SATA Used remote console to boot (VMRC) so I can force into VMWARE/ESXi mode wizard migrated perfectly
  2. this sounds like a great product - much more useful than JUST DSM.
  3. my experience is this : I was not able to deploy using the HTML5 "web UI" - i had to dig out my old 6.0 vsphere client to deploy.

    DSM 6.1.x Loader

    I was wrong - after using the OVF download in another thread - everything is perfect. this was an user error (mine).

    DSM 6.1.x Loader

    Quck update... 1.02Alpha doesn't support LSI 2xxx cards - it never boots after initial installation; remove the card and you get the "please install harddrives" message.
  6. I can provide a working 6.0.x OVA that I have remotely deployed to 6/6.5 ESXi, PM me for info.
  7. I apology again if I went too far - i looked back and a few things can be better said; I have not, but I can; look at what iscsi is doing on my ESXi DSM(5.2), and see what is required for good block access. my setup will NOT be a good test case, I am using SHR - which in all aspects, is file level (or more correctly - quite a few layers to get to block level) - so iscsi will be hampered by that. if DSM is using decent raid (raid-5 with write hole, ) then you should be able to get pretty decent speed. looking at DSM's site : https://www.synology.com/en-us/knowledgebase/DSM/help/DSM/StorageManager/iscsilun looks like it explains it better than I did; but then as you said "devices specifically created for iSCSI, can take advantage of iSCSI and provide the actual performance that it was supposed to offer, everything else feels like a poor-man's version of iSCSI" we can do some tweaking, and some MPIO work - LUN packet sizes, proper raid; LUN allocation unit size (should match your type) but if you really want/need iscsi - DSM may not be for you. for 99.999% of home labs, early mount NFS via fstabs (or other node supported ways) is going to get you what you need. I do not mean to Lecture; there are things I learn every day myself.
  8. you are not quite 100% in your terms sir. the iSCSI presented by WD/Qnap/Synology/Linux - is 100% TRUE iSCSI. you are getting iscsi (a transportation layer (read: networking protocol)- allows the SCSI command to be sent end-to-end over local-area networks (LANs), wide-area networks (WANs) or the Internet) with SAN (Storage Area Network) the Virtual drive you are refering to is a LUN - which is how iscsi and FibreChannel work. LUN : A logical unit number (LUN) is a unique identifier to designate an individual or collection of physical or virtual storage devices that execute input/output (I/O) commands with a host computer, as defined by the Small System Computer Interface (SCSI) standard in more simpler terms - Iscsi is used for LUN access, and in this case we can say a LUN device is a block accessible device. (you are serving a full virtual drive for example) NFS and SAMBA (CIFS) serve FILES. (the ride on the operating systems and Layer 7 networking, not layer 2 as isci) Iscsi is inherently faster for systems designed to use it. because you are working DIRECTLY with block levels. no abstraction layers. where these lower end devices "FAIL" at is speed. if you want faster Iscsi - you need faster drives with faster IO (raid10/SSDs/ETC) and you need to use it for the right reason; it's slow in file because it's not "really" designed for that. - you can 100% saturate a gigabit network with a "whitebox" SAN/NAS - remember - gigabit is slower than most sata3 Spinners. there is more complete information i can provide; if this is questioned. TL:DR - it's real iscsi - iscsi is for full drive sharing (block accessing, say VM images) - cifs/nfs is for files - iscsi (done for the right reason) will always be faster. (yes, I am aware of file-based iscsi - I am not sure I know anyone who actually uses it. it's inherently slow (due to required overhead)) Sources : I am a network/storage engineer EDIT - I have edited this a few times to clarify my hasty writing; forgive me for that.
  9. make sure you are running ESXi 6U2 - then use the web UI : https://ESXI_HOST/ui/ for anyone else using ESXi and want the easy way to update : http://www.v-front.de/2016/01/how-to-use-esxi-patch-tracker-to-update.html
  10. how would I move my current xpenology NAS to this?
  11. just a peice of info - this is with ESXi passthrough : fuuny thing - works find in OSX and WIndows - will try some other methods.
  12. I have tried this with Xpenboot 5.2-5644.4 - and 5644.2 DSM DSM is installed as a ESXi Guest with a RocketRaid 622 in passthrough - lspci showed the device properly; when I insmod rr62x.ko - it always returns with no device present (I can supply acual commands - am on laptop now) any suggestions?
