Dell Poweredge 12G Server Memory Configuration Tool

By admin, September 5, 2012 9:47 pm

Marien left a comment in my blog, in which he pointed out a very useful tool for correctly selecting Dell Poweredge 12G server memory configuration.

For me, highest speed (now it’s in 1600Mhz) is always my first choice, sometimes, I would rather trace off less total memory for the speed as memory is the top competing resource among many VMs on the same host. Therefore, you do need to know DPC (Dimm per Channel) inside out.

Memory power consumption is the 2nd most important factor, so I always select Low Voltage (LV) 1.35 Volts as they do save quite a bit when you add up all the sticks.

Finally, 16GB is becoming the norm these days, a 288GB ESX host is no longer a dream especially when the good news of vSphere 5.1 removed the vTax limitation.

PS. Another thing I learn about the new R720 is the latest 12G server uses at least 1/4 less power than previous 11G R710 which is a great news!

坑爹之作: Toyota 2000 GT 褐色升級版

By admin, September 5, 2012 10:58 am

今天突然發現Autoart釋放出了2000 GT 褐色升級版的衛星圖片。

其實之前已經收齊了金、白、紅、銀4色,這次即將推出的所謂升級版除了輪轂變為鋼絲樣子外(當然這個比CMC/EXOTO差得太遠了),到現在為止我還看不出有什么其它部件有升級的地方,而且我不太喜歡這顏色,加上價錢因素,所以應該再次放棄了。

最近Autoart就藉著這自以為傲的鋼絲輪轂來了個大變身,如馬丁DB5、捷豹E-Type等。
我要明確指出的是價格方面的大提昇。就拿78745(Maroon)這台來說,每一個新的輪轂升級大概值11Euro,價格也硬生生地從97.95提昇到了141.95Euro的驚人水平。

作為一個瘋狂的2000 GT車模收藏家,我認為AA簡直當我們收藏家白痴,這簡單的輪轂換成了鋼絲的樣子就等於要幾乎50%的提價,至於嗎﹖我還沒提4年前買白色的2000 GT時才港幣550左右,大概55Euro,這樣算的話,那可是1.6倍的提昇啊! 看來AA最近的確想錢想瘋了,完全走火入魔了,是否真的如江湖傳聞所說最近AA銷量大減、現金流出現問題那就不得而知了。

我清楚記得當年AA還是五六百的時候,那時候我的收車激情是多麼地高昂啊,當然這些都已經是歷史了。

怪只能怪我太窮,沒錢繼續這份越來越昂貴得嗜好,TNND!

Oh…My…Microsoft Partner Gathering

By admin, September 4, 2012 1:03 pm

Boring as usual, it’s all about Windows 8, non of the sales there have deep knowledge about Windows Server 2012 and Hyper-V 3.0, the ones in front panel just non-stop  blablablala…those noise really put me into sleep, except Microsoft promotion girls are always the center of the flash. :)

I ended up leaving much early than expected, I am not going to attend this kind of seminar anymore in the future for sure, it’s a completely waste of my time.

Joanna Wang 王若琳: I Love You

By admin, August 31, 2012 9:40 am

早上又聽到了這首記憶猶新的歌,其實大約10年前就聽過陶哲現場的表演,說真的,當時沒什麼感覺。

但這首重新編排和由同樣是來自台灣的創作歌手Joanna Wang的全新演繹則給人一種截然不同的感覺,奇怪的是王若琳的聲音竟然帶有些美國R&B的獨特滄桑,不看樣子還真會以為是個黑人女歌手。

VMware Returns to Per Processor License, vRam has GONE!

Last-Import-22

NO MORE vTax YEAH!!!

VMware finally has to face the truth: Sales Record is going Down and competitor Microsoft is chasing like a dog, almost onto its foot.

It’s a great start this week’s VMWorld 2012 by announcing the cancellation of vTax from VMW’s new CEO Pat Gelsinger and even the exiting CEO Paul Martiz said the vRam thing was indeed TOO COMPLICATED to implement.

So I am sure we will see 1TB/2TB ESX host to become a norm pretty soon and not to mention the cost per VM will be greatly driving down and become much more competitive than Hyper-V or XEN.

Bravo! It’s time to buy some more VMW now!

Finally, I can’t wait to attend the latest VMware conference in Hong Kong and experience those exciting new features from ESX 5.1!

PS. Congratulations to Equallogic, they have won The Finalist of the Category New Technology in VMworld 2012 Awards.

Update: Sep 10, 2012

VMware vRAM still in place for VSPPs
VMware isn’t completely “striking the word vRAM from the vocabulary of the vDictionary,” as CEO Pat Gelsinger said at VMworld. The controversial pricing model will still apply to those running vSphere in public clouds.

Participants in the VMware Service Provider Program (VSPP) will continue to charge according to the amount of memory allocated per virtual machine (VM). Some service providers said they have no major problems with vRAM licensing and pricing because it aligns well with the public cloud’s pay-per-use business model.

“We’re fairly happy with where we are right now,” said Pat O’Day, chief technology officer of VSPP partner BlueLock LLC.

But a West Coast-based VSPP partner said VMware vRAM can put VSPPs at a disadvantage against other service providers, especially when it comes to high-density hosts.

“We’re seeing a lot of large service providers and industry players moving off of VMware and into open source … and that’s putting competitive pressure on us,” said the partner, who spoke on the condition of anonymity.

How VMware vRAM works for VSPPs

The VMware vRAM allocation limits for VSPPs are different from those abolished at VMworld, which were for business customers purchasing vSphere. For VSPPs, vRAM is capped at 24 GB of reserved memory per VM, and VSPPs are charged for at least 50% of the memory they reserve for each VM.

Also, unlike with the licenses for private organizations, VSPP vRAM is not associated with a CPU-based entitlement, and it does not require the purchase of additional licenses to accommodate memory pool size limits.

The infrastructure for BlueLock Virtual Datacenters runs on Hewlett-Packard servers, packing in 512 GB of RAM each. VMware licensing is a very small percentage of BlueLock’s overall costs, O’Day said. Given the 24 GB per VM cap, the company could probably add even more RAM to each server, O’Day said.

“But that’s not worth disrupting our business model to do,” he added.
VSPPs’ VMware vRAM reactions

VMware discontinued the wildly unpopular vRAM licensing and pricing model for business customers after more than a year of discontent. Some VSPPs worried the move away from vRAM on the enterprise side would also affect their businesses, according to an email one VSPP software distributor sent to service provider clients.

“We have received feedback from quite a few partners who have expressed concern to us over the announcement that VMware is moving away from vRAM,” the distributor said in the email, which was obtained by SearchCloudComputing.com. “The question to a person seems to be, ‘How does this impact me as a VSPP partner whose billing is completely based around vRAM?’ The answer is, not at all.”

But the West Coast partner, who received that email, said the cost of memory on high-density hosts can eat into VSPPs’ margins or force VSPPs to pass the costs on to end-user customers. This partner offers services including hosted virtual desktops that don’t run on VMware View, and vRAM can cost as much as $7 per gigabyte under this model.

“If you’re trying to provision a desktop with four gigabytes of RAM … the memory alone is $30,” the partner said. “You’re at a significant disadvantage as the market tries to bring the price down.”

Furthermore, the complexity of the licensing model makes it difficult to set the monthly costs of vRAM based on usage, the partner said.

“You basically hand VMware your wallet and let them take whatever they want,” the partner added. “… The pricing is so complicated, we have no way to estimate how much we’re going to pay VMware at the end of the month.”

In a blog post discussing the continuation of vRAM for VSPPs, VMware said the vRAM model allows service providers to sell more computing capability from the same infrastructure, and to control the memory oversubscription and service profit margin through allocated vRAM delivered to customers.

VMware vRAM timeline

July 2011: VRAM licensing and pricing model announced at vSphere 5 launch.

Aug. 2011: VMware increases vRAM limits in response to complaints.

Aug. 2012: At VMworld, VMware eliminates vRAM licensing and pricing for business customers.

賽車的種類 (轉文)

By admin, August 28, 2012 8:58 am

今天看到MC論壇magic1911的美文,又學到o野啦!

1.賽車是分成很多類的,有賽道耐力賽、方程式、拉力賽、爬山賽……..,而每大
類比賽又可細分出好几种小類來;

2.單拿賽道耐力賽來說,不同的賽車可分成很多不同的組;

3.不同的分組規則是隨著時間改變的,以賽道耐力賽來說,60年代大致分:S組、P組、
GT組;70年代:gr1-gr5;80年代:A組、B組、C組;90年代到現在:GT1、GT2、lmp1、
lmp2。(我這只是個大致的分類,時間線不太准,分的也不細)

4.在賽道耐力賽的這類分組中有一組賽車被稱作原型車組,60年代的P組、70年代的
gr.5組、80年代的C組、現在的lmp組就是這一類,這种車不做量產,只為比賽單獨
成產几輛。330P4屬于60年代的2.0+P組,原型賽車的一种;而GT40賽車(分MK1-4???記不清啦反正有好几种型號)有些型號屬于P組,有些屬于S組。

因為GT40的有些型號推出過街車版,這种型號的GT40賽車被認為是高性能街車的改裝版,也就被分在S組了。而對于只出過几輛原型賽車的GT40型號,則被認為是P組。(gt40的MK1-4等,雖然樣子差不太多,他們在配置上可是相差的非常之大的,些型號要被看做是不同的車)

總之賽車的分組、規則、限制,非常复雜,而且經常性的會有所變化。此外1967年330 p4在比較大型的比賽上只在Daytona 24 Hours中贏了FORD和Prosche。lemans24h和Sebring 12 Hours都是FORD贏的,Targa Florio是Porsche贏的。而Ferrari就是從330P走下巔峰的,從此至今再也沒拿過lemans 24H的全場總冠軍。
