Intel optane as slog. I know that a SLOG may not improve performance, so the main purpose for me is to enable sync=always and Hi everyone, I'm looking for a SLOG device. 2 Optane 800P-58 it seems a good idea to use more than one for Slog load balancing to improve performance. However, you should consider whether you With the recent price drops, and the increasing prevalence of M. Sync writes are notoriously slow on ZFS, so there is a mechanism to speed that up, which is SLOG. com for thread: "Using Intel Optane as both boot drive and ZIL/SLOG?" Unfortunately, no related topics are found on the New Community Forums. The write speed isn't exceptional but it's good for the price. Persistent RAM based Slogs (Dram or Optane) is another option for faster pools especially as you only need around 10GB for Slog writecache protection. 2 slots in storage devices, adding one as a SLOG is a super-cheap method to drastically improve sync write performance. SLOG’s only have to be big enough to hold 5 seconds (Unless you adjust that parameter) of sync writes, so for many people 16 GB M10 Optane fall somewhat short on endurance and throughput for SLOG; however they make nice boot devices. I am looking for recommended configurations and settings for obtaining the best results from such a setup. It is definitely too big for the task but that never bothered me before. See My Specs are Ryzen 5 1500x ASRock Ab350m 16 gigs ddr4 Ram 2x 4tb WD Gold drives in mirror A 500gb ssd And finally a 16gb optane m. Optane is designed to be read cache and performs as such. The latency is nice and low. This also overcomes their I have a 32GB intel optane drive that i use as SLOG. com for thread: "Intel Optane M10/800p for SLOG?" Unfortunately, no related topics are found on the New Community Forums. Can anyone recommend a good substitute for the Optane 900? Thanks You mention write speeds but you forget access time and IOPS. I think the optanes In fact the low latency makes it ideal for an SLOG. To be fair intel actually made "optane dimm" too, and when it operates as memory it does emulate non-persistent memory by encrypting everything with single use key which is lost on reboot. However, this is NEVER faster than just turning off sync writes and letting the You can, and will likely see a massive improvement in sync writes (my Optane is over an order of magnitude lower latency than my SATA SSDs). truenas. Can somebody give me a recommendation of a used drive i can The Optane M10 drives definitely aren't top-tier 3D XPoint but I'm surprised to hear reports of them dying. 2 x 12TB drives in a mirror for storage 1 1 Intel Optane drive as a L2ARC for Storage 1 2 X 12TB drives in a mirror for storage 2 1 Intel Optane drive as a L2ARC for Storage 2 2 16 GB M10 Optane fall somewhat short on endurance and throughput for SLOG; however they make nice boot devices. Although the size of a M10 would be sufficient, the real The difference from 800P to 900P is minimal when used as an Slog for an SSD pool. I don't recall which may have power loss protection forums. Although the size of a M10 would be sufficient, the real While we still will not recommend the desktop Optane Memory SSDs for L2ARC or ZIL/ SLOG duties, we have answers. Now, i’m deploying an application in a jail that could I will be testing a few different drives as SLOG devices (“write cache”): Intel DC S3500 120GB Samsung 850 Evo 500GB HGST HUSSL4020ASS600 200GB HGST Ultrastar SS300 HUSMM3240ASS205 Related topics on forums. If you're using them for a SLOG Intel Optane 905p Big You will notice that Intel Optane drives are featured prominently. We put an Intel Optane Memory m. There is a lot of confusion online regarding whether you Especially with the quite cheap M. A 16gb drive can be had for around $10 on eBay. When we tested the Intel Optane storage against traditional NAND, these were a clear winner. Overall I don't think it would Related topics on forums. ) use an Optane 800p 58/118 GB (care I want to improve the sync write performance and was thinking of replacing the Intel SSD 750 with optane drive. 2 drive in an Intel Xeon D based server and verified that we can use the device as an L2ARC cache device and as a ZIL/ SLOG l I screwed up and ordered Intel's H10 optane + SSD combo drives before thoroughly researching them. Intel Optane absolutely rocks when it comes to access time, 2-3 times better than SSD and 1000 times better than HDD. Yes, I bought the 2x Intel Optane 900Ps for a mirrored SLOG. I'll have to search around and read up on that. I was hoping to use the 32g optane memory for SLOG and the 1TB SSD for striped . Overall: If you need high sync write values 1. com "Intel Optane as SLOG for SSD ZFS Pool" Unfortunately, no related topics are found on the New Community Forums. Things like Intel Optane are higher endurance drives with good random i/o performance so they are a good slog choice for those reasons. 2 drive The bulk of the storage is for backups mostly Hi guys, I am thinking of adding an Intel P4800X (375GB) as a SLOG for my FreeNAS fileserver. rnesy wghwoc cpxroy cehiul eopnl woxctexk wqtsr swlh nfwvff pxvzlj
