https://community.hpe.com/t5/disk-enclosures/storageworks-3000-array/m-p/2990748#M8653 Hi,<BR /><BR />I have a StorageWorks 3000 Array attached to a Sun E450 Server, the array currently has 6 x 18GB disks in it configured at RAID5.<BR /><BR />I need to add some additional capacity by adding drives. <BR /><BR />The 18GB drives are end of life but i can get hold of 36GB drives instead - Can anyone qualify that there will be no technical issues running this 36GB disk along<BR />side the original 18GB disks in a single RAID5 set? Will I get the capacity of only 18GB out of it or the full 36GB?<BR /><BR />Points waiting!<BR /><BR />Thanks in advance.<BR /><BR /><BR />James Fri, 06 Jun 2003 07:15:36 GMT James Anker 2003-06-06T07:15:36Z https://community.hpe.com/t5/disk-enclosures/storageworks-3000-array/m-p/2990748#M8653 Hi,<BR /><BR />I have a StorageWorks 3000 Array attached to a Sun E450 Server, the array currently has 6 x 18GB disks in it configured at RAID5.<BR /><BR />I need to add some additional capacity by adding drives. <BR /><BR />The 18GB drives are end of life but i can get hold of 36GB drives instead - Can anyone qualify that there will be no technical issues running this 36GB disk along<BR />side the original 18GB disks in a single RAID5 set?

It's not a technical problem, though - it's related to how the array allocates data blocks from the disk pool and load-levels the drives.<BR /><BR />Mixing drive sizes in a disk pool may make your performance uneven.<BR /><BR />...and yes, you will get the full capacity of the drive added to the disk pool - it'll use the whole drive.<BR /><BR />You might want to try partsurfer to find 18GB "replacement" drives. <A href="http://partsurfer.hp.com/cgi-bin/spi/main" target="_blank">http://partsurfer.hp.com/cgi-bin/spi/main</A><BR /><BR />Good luck,<BR /><BR />Vince Fri, 13 Jun 2003 17:00:46 GMT https://community.hpe.com/t5/disk-enclosures/storageworks-3000-array/m-p/2990749#M8654 Vincent Fleming 2003-06-13T17:00:46Z
