I have a question and maybe one of u can help.
The situation is as follows:
We have a MFSYS25 with two Storage Controllers and two switch modules.
Storage Pool 1: 5 * 110GB SSD
Storage Pool 2: 6 * 600GB SAS (1 for Hot spare)
Storage Pool 2 is configured with two Virtual Drives, each 1115GB and used for VMWare ESX environment as two Datastores
We want to add 3 * 600GB SAS to Storage Pool 2 to get more performance and storage.
Does anyone have experience whit this process and do you have advice in this process? What should we take into consideration when expand our storagepool? I have some questions that need be answered before I can choose a strategy.
Q1: How long can take the Expand operations with this configuration. Would it be Hours, Days or a weeks?
Q2: Does this process affect the performance for my current running VMware Virtual Machines?
Q3: How reliable is this process. Does anyone have experience in failing situation?
Q4: Is there difference in adding all three HDD’s in one process(I suspect this is best?) or do I need to add one HDD at a time?
Q5: Does the cache write back settings affect on this process? Is there a best option?
Thanks in advance for any reactions
My situation is not exactly the same as yours, but I have successfully expanded a storage pool by replacing smaller drives with larger drives. I documented the process here How to upgrade all drives in a storage pool to expand size on MFSYS25?
