Guest asrequested Posted February 20, 2017 Share Posted February 20, 2017 Oh, that is true. I would still benefit from it tho. I got the 10Gb connection up, all servers have RAID 0 SSD's so transfers should get a nice boost from 2 SSDs working cache (I hope, tests will be next week only...) RAID 0? That's a bit risky!

PenkethBoy 2066 Posted February 20, 2017 Share Posted February 20, 2017 (edited) It's not about realtime duplication. It's if you have and kind of duplication. I have enabled backup, so this would apply to me. If you have duplication enabled but only one SSD, an archive drive will be used for the other copy during balancing, until balanced. Having two SSDs, both of those will be used while balancing instead of an archive drive. Close If you have duplication enabled but only one SSD, an archive drive will be used for the other copy during COPYING (too the pool) and both of those will be used while COPYING instead of an archive drive. Balancing is more redistribution of data across archive disks which includes emptying ssd cache disks - depending on the rules you set The Cache is Basically a similar idea to Raid 1 (although its not riad) Edited February 20, 2017 by PenkethBoy Link to comment Share on other sites More sharing options...

Balancing is more redistribution of data across archive disks which includes emptying ssd cache disks - depending on the rules you set The Cache is Basically a similar idea to Raid 1 (although its not riad) any better That's wrong. This is a balancing plugin. Not a speed up copying to pool plugin. Reading the notes, it says nothing about copying to the pool, only about balancing. The SSDs are used to hold the new files, until space is made for them. And I would assume they are also used in the process of moving the other files on the archive drives, to allocate space. StableBit DrivePool Balancing Plugin - SSD Optimizer ==================================================== Author: Covecube Inc. With this plug-in you designate one or more disks as special SSD disks. SSD disks will receive all new files created on the pool. It will be the balancer's job to move all the files from the SSD disks to the Archive disks in the background. You can use this plug-in to create a kind of write cache in order to improve write performance on the pool. Optionally, you can also set up a file placement order for your archive disks, so that they will be filled up one at a time. * This plug-in replaces the "Archive Optimizer" and should not be used together with it or the "Ordered File Placement" plug-in. * Any time the SSD designated disks will have data on them your pool condition will be below 100% because those files have been scheduled to be moved off of those disks on the next balancing run. This is normal. * If you are using duplicated files, then you should specify multiple SDD disks or else the system will fall back to an Archive disk for one or more of the file parts. * If you've selected the option to "Move the existing files into the predefined order on the archive disks" and you have duplicated files, it may take more than one balancing pass to get everything organized. * Because this plug-in is very specialized, it should generally be used by itself. * If you've created file placement rules that are attempting to keep files on drives that are designated as SSDs, then you should disable the "Unless a drive is being emptied" option, under the "File placement settings" category, on the "General" tab. Otherwise, your File Placement rules will not be respected by this plugin (because it is emptying the SSD drives). Link to comment Share on other sites More sharing options...

What the guide is saying is that it's recommended to use more than one, but not essential. As you have duplicate files, they recommend using two SSDs so that your archive drives aren't needed to fulfill the rest of the load. Link to comment Share on other sites More sharing options...
PenkethBoy 2066 Posted February 20, 2017 Share Posted February 20, 2017 Nope sorry its the way you are reading it "With this plug-in you designate one or more disks as special SSD disks. SSD disks will receive all new files created on the pool. - the SSD cacheIt will be the balancer's job to move all the files from the SSD disks to the Archive disks in the background. - balancing your pool You can use this plugin to create a kind of write cache in order to improve write performance on the pool." - this is where you can use the extra speed of your new network The ssd Optimizer actually does not balance anything - yes it has rules for the balancer rules engine to use - disk order, whats a ssd drive etc - if you remove it balancing still occurs but you lose the ssd cache etc The balancer is the main engine that takes info from the various plugins and any options you specify on its page. There is a lack of punctuation in the wording you have copied and it could be worded better "StableBit DrivePool Balancing, Plugin - SSD Optimizer" The confusion may come from the fact the SSd optimizer does two things 1) the ssd cache technology and 2) provides extra rules to the balancer - it is a specialised plugin and does a lot more than the rest but is very useful The copying i am referring to is copying from a data source to the pool - ssd optimiser sits in front of you pool and accepts the data - this gives you the speed increase in copying across your new 10g network Later when the balancer does its work it copies the duplicated files sitting on your ssd's to the pool - making sure it maintains the duplication by putting the copies on different drives. Duplication is something separate - it can be real time as you copy data to your pool, off line at night if you have real time duplication turned off or if you manually change some duplication parameter through the interface. Hopefully that makes it clearer - when you see it work it will be a bit clearer also Link to comment Share on other sites More sharing options...

Yes not essential but... so if you have one ssd and x2 duplication set (assuming real time duplication is on - it is by default) when copying to the pool One copy will be saved on the ssd and one copy on an archive drive - speed of copy limited by speed of HDD if you have two ssd's and x2 duplication set when copying to the pool one copy goes to ssd one and another copy goes to ssd two - speed of copy limited by pool ssd or network speed or source disk speed (if this is an ssd also - bingo 400MB/s + across your 10g network) Link to comment Share on other sites More sharing options...
Guest asrequested Posted February 20, 2017 Share Posted February 20, 2017 (edited) No, I disagree with you. It clearly states it's a balancer, and is in the balancer section of the software. It just allows you to designate SSDs in the pool to better the process. That it allows us to copy to the pool, faster, is a fringe benefit. What if you were to rip a disc directly to pool? Copying is irrelevant. It's primarily designed to make balancing quicker and more efficient. Even the developer says it's a balancing plugin. http://community.covecube.com/index.php?/topic/629-ssd-optimizer-balancing-plugin/ Edited February 20, 2017 by Doofus Link to comment Share on other sites More sharing options...
PenkethBoy 2066 Posted February 20, 2017 Share Posted February 20, 2017 Nope sorry you are miss reading it I'm not trying to be obtuse but help you understand what you will see happen when you use the ssd's you have on order and from experience using this software. ...its the balancer's job etc - that's not the plugin (although i agree you could read it that way) - which adds extra rules to the balancers engine along with any other plugins which add more rules. The rules get processed together not one after the other - they are weighted based on some algorithm that i have not seen the rules for - as they are not published if you copy any files to the pool it goes to the ssd's - then at some other time the balancer engine kicks in and moves them to the archive disks - depending what options you have set Yes they use the term balancing plugin which is confusing as they are not consistent overall their documentation. Yes that tab should read plugins rather than balancers - the settings tab is the interface for the balancer engine It has two purposes as a write cache (when you copy/move data to the pool) and to provide balancing rules for shifting the data to the archive disks in the way you want. If it makes it clearer - consider the ssd's as say a small pool of their own which gets flushed to the hdd pool periodically. Without the cache the max speed you will get copying to the pool will be limited to the HDD that the data is being used at that time - add in the ssd's cache and you will get 400 mb/s + rather than say 150MB/s+ for a HHD.

Guest asrequested Posted February 20, 2017 Share Posted February 20, 2017 Do you have more Info on that, I really want to understand it more. Right now it's set up to use the SSD as caching and duplicates to the drive. I understand your theory tho, but I think it can work as solo SSD too, with some performance impact (as it duplicates to multiple drives, impacting your read times depending on how many copies you make.) Having a PCI SSD tho would fix that as you can hit 1k read most probably haha Take a look at this post Link to comment Share on other sites More sharing options...
