Hey Checkyourlogs Fans, I just wanted to make you aware of a critical Firmware Update that is require for your Intel DC S4510 and S4610 Drives. In the fine print of the release notes you will see a critical note: Resolved 1.92TB and 3.84TB SKUs may become unresponsive at 1700 hrs of cumulative Idle Power On Hours.

Hey Checkyourlogs Fans, Tonight @SifuSun (Cary Sun) and I were doing some routine maintenance of a 2-node Storage Spaces Direct Cluster that was having issues with checkpoints locking up during Veeam Backups. We went through the normal process putting the nodes into maintenance mode, patching, and waiting for storage jobs to complete before moving on to the next node. We found an interesting scenario where after the first node was complete and we patched our second node look at what happened to our cluster. The above screenshot was what we first noticed with the Cluster IP going offline. Even...

Performance Tuning Deduplication on Windows Server 2019 ReFS and #StorageSpacesDirect

Hey Checkyourlogs Fans, In the previous post, we talked about the essential operator’s report for Storage Spaces Direct in Windows Server 2019. Today, I want to talk to you about the performance penalty that is required to run Deduplication on Windows Server 2019. Nothing in life is free, and this is certainly the case for Deduplication.
