I’ve encountered a problem when installing Windows Server 2008 R2 SP1 today and found the reason and solution pretty easy. It was due to Veeam B&R v5.0 automatically Disabled automount for SAN mode and W2K8 R2 SP1 requires automount to be enabled.

Solution:

1. Disconnect all active iSCSI connections and REMOVE the Target Portal from iSCSI favourite tab. 

2. From command prompt, issue the followings:
> diskpart
> automount enable

3. Reboot the server then go ahead and upgrade your W2K8 R2 with SP1, it will take about 50 minutes to complete, yes, it did take that long even on latest powerful server.

4. Then issue the following AFTER reboot:
> diskpart
> automount disable

5. Reboot the last time and then re-establish all previous iSCSI connections as usual.

規則1:跟人決定前途

民初名妓小鳳仙，要是找個民工，掃黃就被掃走了；
她找蔡鍔，就流芳千古；
要是跟孫中山，那就是國母。
所以不在于你干什么，而在于你跟誰干。

規則2：時間決定性質

趙四小姐16歲去大帥府，去1年，是奸情；
去3年，是偷情； 一去30年，那就是千古愛情。
很多事情不是不做，而是要看做多久。

規則3：關鍵崗位要有自己人

男子去提親，女方家長：請自我介紹。
A說：我有1000万；
B說：我有一棟豪宅，价值2000万；
家長很滿意。就問C，你家有什么？
C答：我什么都沒有，只有一個孩子，在你女儿肚子里。
AB無語，走了。
這個案例告訴我們一個淺顯的道理，
核心競爭力不是錢和房子，是在關鍵的崗位有自已的人。

規則4:做人要有屏功

女秘書神色凝重地說：王總,我怀孕了。
王繼續低頭看文件,然后淡淡一笑:我早結扎了。
女秘書楞了一會媚笑道:我是和您開玩笑呢!
王抬起頭看了她一眼，喝了口茶說:我也是。
這個案例告訴我們, 在江湖上晃的人,遇事不要慌,先讓子彈飛一會!

Today I finally got a chance to hit with the latest racket from Yonex, VCore 100 S, S specifies for Spin. It’s also the choice from current world #1 Caroline Wozniacki who just switched from Babolat recently.

I found indeed I can hit much better quality top spin with confidence ever than before, thanks to VCore’s technology “Spin to win with 3D Control”.

In fact, there isn’t much to compare with my 25 years old POG, I must admit the technology is definitely there this time and it did help me to improve my baseline style game, not to mention VCore 100 S also helped me to serve with more spin and angle, it’s simply amazing and I start to love it!

I am pretty sure now this is the one to go when it’s available in local store later.

馮小剛曾這樣形容姜文。「有一位導演曾對我說過這樣一番話，讓我出了一身冷汗。他說：電影應該是酒，哪怕只有一口，但它得是酒。你拍的東西是葡萄，很新鮮的葡萄，甚至還掛着霜，但你沒有把它釀成酒，開始時是葡萄，到了還是葡萄。另外一些導演明白這個道理，他們知道電影得是酒，但沒有釀造的過程。上來就是一口酒，結束時還是一口酒。更可怕的是，這酒既不是葡萄釀造的，也不是糧食釀成的，是化學兌出來的。他還說：小剛，你應該把葡萄釀成酒，不能僅僅滿足於做一杯又一杯的鮮榨葡萄汁……這位導演名叫：姜文。」

I just came across this GREAT PowerPoint presentation today, I wish I had it 6 months ago, it really helps you to clear the sky and understand many things before making the design and purchase decision.

At first, I got very poor performance when I was trying to svMotion a 20GB VM within the same Equallogic SAN between different volumes, it took over 20 minutes to complete, I thought there must be something wrong as I’ve already enabled VAAI.

After searching the net and discovered the problem is due to Different Block Size between the two volumes (1MB vs 2MB) that will actually disabled VAAI feature.

So choosing the volumes with the same block size, I was able to reduce the time by almost 10 times!!!

See attached graph, 15:22 to 15:42 is the one without VAAI, 15:50 to 15:52 is the one with VAAI.

In additional, I have implemented Storage I/O Control today and found Storage vMotion with VAAI isn’t affected by SIOC as the whole svMotion is offloaded on to the EQL array, so SIOC won’t really kick in, you may say svMotion with VAAI is “Out of Control ”, this is another great thing about VAAI!

Finally, I do think SIOC is one of the best feature in ESX 4.1 for many cloud hosting providers as they can finally meet their storage SLA now besides the CPU and memory.

It’s nice to have this compliment plug-in for your Equallogic and VMware vCenter.

• EqualLogic Datastore Manager – Allows administrators to provision new Datastores, expand existing Datastores, and monitor storage usage in the VMware Datacenter.
• Auto-Snapshot Manager/VMware® Edition 3.0 – Creates and restores Smartcopies of Hypervisor consistent Virtual Machines (VMs). Utilizes snapshots, clones, and replicas within PS Series group allowing for fast restoration or disaster recovery.
• EqualLogic Virtual Desktop Deployment Tool – VMware View aware desktop provisioning wizard which allows the deployment of manual virtual desktop pools using array based space efficient thin clones and also allows the refresh of these pools.

  
  Note: These tools can be launched from the Home screen of vCenter and also from the new context sensitive tabs and right-click menu options that are added with the plug-in.
  

Btw, I am also getting the Dell Management Plug-in for VMware very soon from my Dell account manager, can’t wait to try it!
