<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi all
<div><br>
</div>
<div>I'm currently about to deploy some flash systems (FS-900) to take our metadata for one of our Spectrum Scale file-systems. We use 4k inodes for this file-system.</div>
<div><br>
</div>
<div>On the FS-900, when creating a volume, we get a choice of 512b or 4k sectors. Does anyone have a suggestion on this? On a spinning disk RAID array, I get what a strip size is and we'd use multiples of the stripe where possible for the block size.</div>
<div><br>
</div>
<div>Is the sector size on the FS-900 the smallest chunk that can be written out? And so would it make sense to use 4k sectors for 4k GPFS inodes right?</div>
<div><br>
</div>
<div>Related. In the deployment guide for the FS-900 arrays, if one is using a file-system (e.g. XFS) on the array the guide talks about aligning the partitions with with array, when GPFS is used on a storage array, does it automatically work out the sector
alignment?</div>
