New build, synology migration and sanity check

Recommended Posts

Hi everyone,

 

I'm planning on moving away from my current synology unit to a new (first time) xpenology build.

 

Current setup:

RS2418RP+ DSM 7.1.1

12x 8TB HDD in SHR1

 

Planned setup:

Intel i3-12100T

Asus Prime Z690-A

32GB DDR4 3200Mhz

3x or 4x M.2 NVME drive (tbd)

12x 8TB HDD 

Inter-Tech IPC 2U-2412 (12x hotswap bays with sata/sas backplane)

LSI SAS9300-16i HBA in IT mode (non-raid)

Mellanox ConnectX-4 Dual Port 25Gbe (MCX4121A-ACAT)

 

So I've been doing some reading around the forums about which platform to use and it seems DS3622xs+ is most suitable, please correct me if I'm wrong though. I'm not looking to use the iGPU at all, so no support needed for that.

 

I have a couple of questions:

 

1. Is the LSI HBA supported?

2. Is the Mellanox NIC supported?

3. Can I migrate my existing SHR1 array without formatting? I'm reading that SHR isn't enabled/supported on newer models by default?

4. Can I use the M.2 NVME drives to create a new volume? Not looking to use these for caching but planning to create an all-flash volume as datastore for vmware. 

5. I'll soon be running into the 108TB volume limit with this array. Any way to convert to 200TB without formatting? Synology says that you have to recreate the volume, but maybe there's some magic that can be done with Xpenology?

 

Please let me know if I've missed anything obvious. Thanks in advance!

seeing this i'd say at least now

https://github.com/pocopico/redpill-lkm/commit/787faf5ece6afe851421dabb15c924757a3c60cc

// by jim3ma:
    // dsm 7.2 check syno_port_type in sd_probe, when syno_port_type == 1(SYNO_PORT_TYPE_SATA), the disk is sata
    // for disks from hba card like Microsemi Adaptec HBA 1000-8i with aacraid driver, syno_port_type is always 0, we need change it to 1(SYNO_PORT_TYPE_SATA), otherwise sd_probe will return error with -22
    // solution: update syno_port_type in hba driver

1st thing can be to check if its supported by dsm itself (on dsm types supported by synology for mellanox)

https://www.synology.com/en-global/compatibility?search_by=category&category=network_interface_cards&filter_brand=Mellanox&display_brand=other

your's is supported and when checking the compatibility row from the link above

and as long as the the loader make support wotth (no likely) the it should at least working in the official supported systems, often the driver in the loader are newer and stretch over more systems then synology supports (like having mlx support in units that in original dont have a pcie slot like dva1622 as a gemini lake system)

yes you can even check synology's faq and it should say this, shr is just a disabled option when creating a new array (and even that can manually changed)

existing arrays will work as its a general dsm feature and as all systems come (more or less) as the same dsm version the code is present (exceptions will be code that is part of the kernel, if that is left out when compiling the kernel its not persent, example can be raid f1, not pesent in consumer units and can't be added easily, when needing it you need to chooese a unit in the loader that comes from synology with support for raid f1 as we use syno's original kernel)

synology has enabled that for some units and it was "extended" from xpenology users to more (all?) units, if you want to be on the safe side look up on what unit synology supports it and choose one of there in the loader, prevents problems when updating and m.2 volume is gone/missing after update - when using a non official unit then thoroughly read about the things to keep in mind and the risks

thats all about dsm itself and you can just use the information synology has about it

https://kb.synology.com/en-in/DSM/tutorial/Why_does_my_Synology_NAS_have_a_single_volume_size_limitation

keep to that and you wont have problems, DS... units in general seem not to come with 1PB support now but that might change when bigger disks will be more common and synologys customers with DS units will stumble more often, its a software and marketing thing i guess

 i did not look up about that in the forum, it might be as simple as enabling shr after installing to get 1PB support, its still corner case but will get more important the next two years
