小桌子蠻有趣的,但是並不像David Roth使用的桌子會需要magxxt,這個小桌子可丟給外行人檢查。
沒有任何機關(應該說機關外行人看不懂)

各家儲存自動分層概述與比較
之前老聽partner或客戶說NETAPP號稱支援儲存自動分層(Virtual Storage Tier),後來研究了一下,實際上根本是是使用Cache技術達成。
NetApp把儲存自動分層分成兩個類型,一種是NA自己運作的方式,就是Cache,一種是其他廠商運作的方式,叫做資料遷移分層。

N2G-N3
在產品問世前有跟同好聊過,這個道具的組成。畢竟N2G的產品也是從Johnny wong系列衍生出來的發想與創意。
本來想直接從淘寶跟N2G買的,但是運費加起來沒有比較便宜,就跟噓迷子買了。

vSphere 5.x 支援的UNMAP功能-慎用
- Although simplyfied, UNMAP is still a manual process you have to trigger on the command line. It is still not an inline feature!
- it puts very high load on your storage subsystem so really think twice before reclaiming space (probably this feature should currently ONLY be used during maintenance windows)
- space reclaiming, of course, only makes sense if you delete whole VMs/virtual disks on a datastore. It won't work for files deleted inside the guest OSes
- always consider moving VMs with SVMotion to other datastores and completely delete the empty datastores as an alternative. This will achieve the same result regarding space reclamation but probably with less impact on storage performance

Windows UNMAP 導致SQL backup failure
Recently we’ve been trouble shooting some weird SQL Server to file backup issues. They started failing on the clock at 06:00 AM. We checked the NICs, the switches, the drivers, the LUNs, HBAs, … but it was all well. We considered over stressed buffers as the root cause or spanning tree issues but the clock steadiness of it all was weird. We tried playing with some time out parameters but with little to no avail. Until the moment it hit me, the file deletions that clean up the old backups!We had UNMAP enabled recently on the SAN.
Take a look at the screenshot below an note the deletion times underlined in red. That’s with UNMAP enabled. Above is with UNMAP disabled. The Backup jobs failed waiting for the deletion process.
