  • Your Usable Capacity May Vary – Chuck conducts a thought deployment comparing EMC, HP and NetApp usable space for a 120 disk Exchange deployment. And while he glosses over a couple perhaps non-minor issues (RAID-5 vs RAID-DP and whether EMC’s snapshots are adequately performant), he does hit one of NetApp’s weak spots dead on: Usable capacity, particularly on LUNs if you follow the 100% space reservation recommendation. (Being a NetApp admin these days, I can’t really comment on what he writes about HP – it’s been a long time since I’ve touched that StorageWorks stuff – and I can only repeat what I’ve heard others say about EMC.) More Chuck on this here.

  • Welcome – My friend, NetApp’s Vaughan Stewart: Chad Sakac highlights some flaws in NetApp’s TR-3697 (“Performance Report: Multiprotocol Performance Test of VMware® ESX 3.5 on NetApp Storage Systems”):

    What’s the scoop with:

    * 4K/8K IO size only
    * 2Gbps FC
    * You guys have “throughput/IOPs” shown only in relative, not in absolute.
    * 84 144GB drives with 16 VMs driving the IOMeter workloads with * 10GB of data each on them = 1.3% utilization (rounding up!).
