ZFS should have been great, but I kind of hate it: ZFS seems to be trapped in the past, before it was sidelined it as the cool storage project of choice; it’s inflexible; it lacks modern flash integration; and it’s not directly supported by most operating systems. But I put all my valuable data on ZFS because it simply offers the best level of data protection in a small office/home office (SOHO) environment. Here’s why.
With the advent of AMD Threadripper and Epyc, we are about to see an explosion of PCIe lanes in the pro-sumer and datacenter market. Although many of those lanes will be taken up by conventional PCIe cards, some will be used for SSD’s (M.2 and U.2) or for external connectivity. This is where OCuLink might finally take off: As an AMD alternative to Thunderbolt for external PCIe peripheral connectivity.
From iCloud Photos to Google Drive to NetApp and Primary Data, we’re putting storage wherever it needs to be. And this is a major shift for computing, from the iPhone to the datacenter. Watch this space!
Hard disk drives encounter errors from time to time, so it’s a good thing that most have the ability to recover data anyway. But RAID systems usually have their own error recovery capabilities and can be thrown off when a hard disk pauses I/O. So it’s a good idea to use hard disk drives that allow you to disable or limit error recovery in RAID systems.
I’ve got a lot to say about storage, as you might have noticed from reading my blog. So I finally sat down and wrote a book on enterprise storage. Now you can download the e-book for free, thanks to support from my friends at SolarWinds!
