  5. Hi David,
    I am wondering if you could answer my question regarding XtremIO. XtremIO exposes total and used capacity at volume level (I am using rest to query that and filed name in rets output is logical-space-in-use) and I see that logical used capacity (if I sum up used capacity of all volume) , it comes out to be larger that logical allocated. I see that out of 83 TB allocated logical capacity used is 103. I am not sure if it has anything to do with compression. I appreciate your response on this.

  6. David,

    Your Cisco MDS information is great. I always refer back to your blog when I need a refresher.
