<div dir="ltr">hi, all,<div> We are using gluster 3.5.2 on standard 3TB*12 machines, some hosts also got SSD on the machines as well; <br clear="all"><div>two questions:</div><div>1. Is there mature solution, I can use the SSD as the write cache for sata disks? So I can combine the power of SSD as write cache(and even read cache), and the capacity provided by SATA disks?</div><div> I heard on Ceph there is tied storage solution already, on glusterfs i did't see that on documentation; <br> Anyone used solution like facebook flashcache solution?</div><div><br></div><div>2. As sata disks fails often(relatively, when you got lots of disks...), each time a disk fails, i will have to manually replace the disks, and replace the bricks;</div><div> Can we setup spare bricks?</div><div> Say, I have 12*3TB sata disks, I only use 10 disks as 10 Bricks with data on it, and have 2 disks configured with filesystem, as part of volume, without putting data on the brick/filesystem? So in case on brick fails, this brick automatically replace that failed disks? Just like hotspare in raid?</div><div><br></div><div><br></div><div>Thanks;</div><div><br></div><div><br></div><div><br></div>-- <br><div class="gmail_signature">Regards<br>Zhu Chao<br><br></div>
