    Those SuperMicro cards are HBA's, not hardware RAID cards.

    See thanks to this software system called ZFS there is basically no need for hardware raid, except in a very few specific circumstances. What ZFS does, is combine RAID, volume manager and file system in one piece of software that protects against a bunch of things that hardware raid does not.Bit rot for example is one of those problems that only gets worse as the size of disks gets bigger. Hardware RAID is unable to sufficiently protect your data from bit rot and other silent data corruption issues, while ZFS does because it has control of the entire storage stack.

    A couple of big advantages that hardware RAID used to have were speed and battery backed write cache (to deal with the write hole). On modern CPU's, RAID calculations for huge arrays only use a fraction of the total available processing power, while hardware RAID cards are still using 20 year old processors to do their parity calculations. ZFS also has no need for battery backed write cache to deal with the write hole since it uses a copy-on-write transactional model.

    And now for some big hardware RAID disadvantages.
    • If your hardware RAID controller dies, you're gonna have to find a compatible one to get your data back (or call it a day and restore from backups). If your specific controller is no longer available, you are shit out of luck.
    • Vendor Lockin.
    • Your RAID card is a single point of failure, something which is pretty unacceptable.
    • You'll spend a lot more money on good RAID cards than on good HBA's.
    Where software RAID systems (not just ZFS) have the indisputable advantage, is flexibility.
    • You can create a RAID array with disks spanning multiple completely different disk controllers. For example, you have 6 disks configured in RAID6/RAIDZ2 (double parity). If you spread these out of 3 HBA's, you can not only deal with two disks failing (double parity), but also with one of the disk controllers going kaputt.
    • Using multiple disk controllers also means you can create much larger arrays (RAID60).
    • You can easily transplant the disks to a completely different server, with completely different hardware and get your data back fine.
    ZFS itself has some more really cool features apart from its superior data integrity mechanisms.
    • My ZFS system for example could eventually be made up out of a single pool consisting of 3 striped vdevs that each consist of 6 disks in RAIDZ2. Currently it consists out of only one 6 disk vdev, but extending it with more vdevs and refactoring is trivial.
    • Built in support for both read and write cache disks for the entire array. I've got a couple of SSD's in the pool that speed up my reads and writes tremendously.
    • Built in snapshots, deduplication, encryption and compression
    In short, ZFS is pretty much the best file system you can use at the moment.

    Layer 3 switch 48 ports etc vlans eat up ports very quickly...

    Since the windows phone team FINALLY managed to pull their heads out of their asses and support VPN even if it is only IKEv2 which is a major PITA to setup :mad: Hopefully we will get SSTP in the future.

    Office should own on that 6" screen too

    What a gay switch.

    Did you find that in a dumpster?

    And fucking VLANs don't eat up ports, you fucking windows wanker.

    Stick to drinking the MSCoolaid you fuckstick.

    Dumbass. Also lets see your suggestion for a 48 Gigabit port layer 3 switch...
