Dell’s ESX Monitor and Reporting Tool: DPACK

By admin, December 2, 2011 8:57 am

During the Equallogic Seminar yesterday, Dell’s storage consultant introduced DPACK (Dell Performance Analysis Collection Kit) to us.

Basically it’s a Monitoring and Reporting utility that will run over time (4-24 hours) to collect data (such as CPU, Memory, IOPS, network traffic etc) from your physical or virtual servers.

The best thing is the footprint of this program is very small, about 1.5MB, still remember that crappy Dell Management Console 2.0?

The best part is you don’t need to install it at all, simply run it, key in the server or vcenter parameters, select a time range, run it, wait for a few hours, that’s it.

The output is a single file with extension .iokit, then you are supposed to use the online generator to get the DPACK result in PDF. (http://go.us.dell.com/DPACK). However, the site is currently not working as it’s still not ready according to DPACK team.

So what to do? DPACK team is kind enough, I sent the result.iokit to them and Dell helped me to generate the PDF manually.

Finally, I would say it’s a lite version of Veeam Monitor and Veeam Monitor does a lot more and it’s also free. :)

25年後的法拉利傳奇F40

By admin, December 1, 2011 9:57 pm

之前還以為至少下星期才能從英國運到香港﹐想不到今天Octane最新的一期竟然已經出現在書店的雜誌架上﹐幾乎和英國同步上架﹐真不錯﹗

我作為一個標準的F40狂迷﹐這期當然不容錯過了。

另外最近終于等到了本地實體店售賣京商F40黑色的輕量升級版﹐紅色的椅子﹐真得很好看﹐而且還有大特價﹐但最後還是放棄了。

原因是這黑色的漆面實在不敢恭維﹐才出了那麼幾個星期﹐已經長出了小泡泡﹐這可是價格過千的車模啊﹐京商怎麼就這麼不注重品質呢﹖太令人費解了﹐難道真的是次貨全留在了亞洲區不成﹖

Veeam Backup & Replication v6 Finally Arrived!

By admin, December 1, 2011 4:04 pm

backup_v6_now_available_3

Despite multiple day, Veeam has finally launched it’s flagship product Veeam Backup & Replication version 6.

One of the most useful features I found is “One Click Restore”, because most of the time we do not have the root password of our client’s servers and often clients ask for mistakenly deleted files, so this enhancement is definitely the key reason for anyone to upgrade to v6.

Besides new improved replication is now 10x faster (see this appreciation post), together with throttling bandwidth capping, finally, we can replicate smoothly over our 100Mbps link between production and DR sites.

Last but not least, the scalability of backup agents (server in Veeam’s term), Veeam B&R 6.0 now utilizes proxy concept, so you have a group of backup agent/proxy or bots that will evenly distribute the loading among them. What’s best, you no longer have to login to each backup server (or agent) and you can manage all of your backup jobs on all proxies from a single panel, isn’t this just beautiful! :)

What about v6 now supports Hyper-V? Dohhhh…Hper-V in my own opinion is still not a mature product and it’s fine for lab use, for enterprise? No Way!

After losing a lot of sleep over the weekend working out the kinks and fixing my mistakes, v6 is running great and I can’t believe the speed increase!

Just a few examples:

  • Replicating a file server with 750GB of data, down to 25 minutes total (replicating the data disk only took 6:30)!
  • Replication job on my Exchange server w/ 400GB of mailbox data… 20 minutes
  • Backup job with 6 VMs ranging from 50-120GB, 35 minutes
  • Replication of a 60GB VM running Accounting software over a 20Mbps WAN… wait for it… 4 1/2 minutes!

The kicker here is I’m running 3-4 jobs in parallel now. My backup window has gone from 6+ hours to around 2 hours for nearly 3TB of VM data and I’m finally saturating my disk writes on the backup target. There are, of course, a few minor bugs, but I’m impressed with the quality for a first release after such major architecture changes.

市場上家用HDD+SSD Caching的解決方案

By admin, November 30, 2011 2:23 pm

After some research, looks like buing a pure SSD like Intel 320 SSD (160GB) is more cost effective. OCZ Synapse SSD is a good choice, but only 1/2 the size can be used, as the other half is used for 2nd level caching.

 

市場上SSD+HDD的解決方案有不少:

1.最直接的是SSD作OS+Program和HDD作Data
2.HybridDrive
3.Intel Smart Respone Technology (need Z68)
4.Seagate Momentus XT
5.利用軟件把SSD作為HDD的Caching

各方案比較:
利用60GB SSD大約為HK$800和640GB HD為HK$400作計算

  直接SSD HybridDrive Intel SRT Momentus XT 軟件
價格(HKD) 800 1600 1200 900 1600
每GB價格 13.3 2.5 1.9 0.6 2.5

其實HybridDrive能夠適用於非Z68以及不同OS是對比起Intel SRT和軟件作Caching的好處,而且HybridDrive只佔用1個底板的SATA Port,對於一些已經沒有SATA Port又想upgrate的用家是十分適合的。

再者的是,用家可以自由選擇SSD的容量,雖然Momentus XT有每GB價格上的優勢,但是8GB SLC始終太少,還有的是,HybridDrive可以對整個HDD作加速,因為在一般SSD作OS+Program和HDD作Data的解決方案,所加速的Program會受SSD容量限制,因為不能把半個Program放到SSD,另半個放到HDD,而HybridDrive所加速的Program則只受HDD容量限制,所加速的Program可以大過SSD。

唯一不好的是只support SATA II,不能發揮出SSD的極速,當然,要雞蛋裏挑骨頭還是有的,就是不能在Notebook上用的,如果可以有高階Notebook的解決方案是很好的,畢竟相關技術已經開發,雖然要放到Notebook上是極難的,但如果能夠在Notebook上面使用,相信都會有一定市場的。

 

針對Hybrid Drive而生 OCZ Synapse SSD系列 

ocz

OCZ 針對 SSD Cache 加速應用推出全新 Synapse SSD 系列,能為傳統 HDD 用作讀寫緩衝,支援 SATA III 介面透過自家 Dataplex 智慧型加速軟件,令讀寫性能提升至最高 550MB/s ,達成高性能、高容量與高性價比兼備的 Hybrid Drive 解決方案。

雖然 SSD 在性能上完全壓倒傳統 HDD 產品,但售價高昂加上容量成本難與 HDD 相比較,因此 Intel 於 Z68 晶片組中引入了「 Intel Smart Responed 」技術,能結合 SSD 與 HDD 達成「 Hybrid Drive 」儲存方案,並且得到市場好評,只可惜「 Intel Smart Responed 」技術暫時只能應用於 Z68 平台上。

OCZ 因應市場對 Hybrid Drive 的需求推出全新「 Synapse SSD 」系列,其原理與早前推出的「 OCZ RevoDrive Hybrid 」,但改用 SATA 介面並且不內建 HDD ,而是針對用家正使用的 HDD 進行 SSD Caching 加速,十分適合升級用家。

「Synapse SSD 」採用 2.5 吋 Form Factor ,採用 SandForce SF-2281 控制器並支援 SATA 6Gbps 規格,提供 64GB 與 128GB 容量,採用單顆高容量的 MLC NAND Flash 設計,並且採用了一半的容量用作 Over Provisioning 空間,以提升作 SSD Caching 的性能,達成最高 550MB/s 讀取性能, 64GB 寫入最高達 490MB/s 、 4K Random Write 約 75,000 IOPS , 128GB 入最高達 510MB/s 、 4K Random Write 約 80,000 IOPS 。

「 Synapse SSD 」搭載自家 Dataplex 智慧型快取加速軟體,支援 Windows 7 32Bit 及 64Bit 作業系統,安裝 Synasape SSD 及 Dataplex 智慧型快取加速軟體後,兩個簡單步驟即可組成 Hybrid Drive 配置。

「 Dataplex 」智慧型快取加速軟體能分辨常用的 Hot Data ,將同時寫入至 SSD Cache 及 HDD 中儲存,利用 SSD 改善儲存、讀取速度,非常用的 Cold Data 和大容量檔案會則會直接寫進 HDD 中,能減少寫入次數提升,在性能與 SSD 壽命取得平衡。

據代理商 Microworks 表示, OCZ Synapse SSD 64GB 、 128GB 建議零售價分別為 HK$1,399 、 HK$2,149 ,代理商提供 3 年保固服務。

My Early Xmas Gift: Dell Optiplex 990 SFF Desktop

By admin, November 29, 2011 4:32 pm

Finally, I bought myself an early Xmas gift: Dell Optiplex 990 SFF Desktop!

This is my one and only PC upgrade after almost 13 years. In fact, believe me or not, I am still using the old PIII system (Asus P2B-D, Dual PIII850Mhz, 1GB Ram, 120GB HD, Windows Server 2003 Ent) as I am typing this blog.

There have been probably over 10 PC generations before this upgrade (ie, P4, Core, Core2 now the Sandy Bridge).

The configuration is the latest Intel desktop CPU Core 2, 2nd generation Sandy Bridge i5-2400 with vPro, 3.1Ghz, 4GB (2GB x 2) Ram, 500GB 7200RPM HD, Extra Broadcom NetXtreme gigabit NIC, 8x DVD +/- RW, Windows 7 Professional 64 Bits, MS Office 2010 Home Edition, 5 Years NBD service.

There are several points that I would like to highlight during the selection of this PC: 990ssf

  • Buy Dell, I’ve compared other vendors like IBM/HP/Acer/Asus, nothing even comes close to this 990SFF, similar configuration will cost 20-30% more. Of course, I knew Dell’s inside sales and they have been serving me well over the last 10 years, that’s why I’ve got a good deal.
  • i5-2400 is more than enough, don’t spent money on upgrading to i5-2500 or i7-2600 (4 cores with HT).
  • Sandy Bridge i5-2400 comes with build-in GPU now, it’s 850Mhz HD2000 graphic processor, enough for watching 1080p HD MKV or BD-RMVB. Of course i5-2405S (2.5Ghz) is better as it comes with HD 3000, but Dell does’t sell any 2xx5 or 2xxxS i5 processor, those are for overclock amatures.
  • Ivy Bridge is around the corner, but still have to wait till Mar/Apr 2012 which is too far for me. Besides who knows if there will be any problems in the new chipset (H/P/Q/Z) like before. Remember Sandy Bridge had a serious SATA chipset  problem when they first release in Feb 2011, that most vendors needed to recall defected MBs, so I really don’t want to be that guinea pig.
  • vPro, yes, I definitely want to try this Desktop equivalent of DRAC, saw the demo on Youtube, seems interesting.
  • I want the Energy Efficient Option (90%) version of 990 SSF, but it’s not available locally, neither does Dell offer 16x DVD, also no low-power version of i5. If you are in US, you can order i5-2400S which is only 65W comparing with 95W of i5-2400.
  • Found out the only Intel desktop chipset supports VMware ESX5 VT-D is Q67 and Z68, and there are less than 3 SFF in the market offer Q67 chipset, Optiplex 990 is one of them.
  • People said default installation of ESX5 won’t work due to the on-board Intel 82579LM NIC is too new, probably ESX5 Update 1 will add this driver and solve the problem. For now just use a Boradcom NIC instead, or even a cheap Realtek will do.
  • I compared the cost of DIY PC with Dell Optiplex 990 SSF, almost same price but Dell has 5 years site visit full warranty, I really don’t want to carry each failure piece to it’s corresponding distributor for repair and wait for over 1 week, I really hated that, no more!
  • Dell’s Harddisk and Ram is still way expensive (100% more) than others even after huge discount, so I am going to buy from local computer shops, a 4GB 1333Mhz Ram is only USD20 or less, too cheap to be true! Just be reminded, bring the actual ram over to the computer shop as I heard the Optiplex ram is low profile type.
  • Optiplex 990 SSF includes with many great software such as PowerDVD, Roxio Creator, Dell Backup and Recovery Manger (I will use Acronis still) and best of all Microsoft Office Starter (with Word and Excel only and that’s all I need really). It also includes PowerPoint Viewer 2010, to view and print PowerPoint slides and shows. In case you don’t know, there is also also a version called Office Web Apps which include online versions of Word, Excel, PowerPoint and OneNote.
  • Oh…I just read about the new coming desktop will have 8 ram slots (X79 MB with latest  Sandy Bride E processor, supports  Ivy Bridge and native USB 3.0 of course), so you can have 32GB ram for ESX for less than USD160, (still it’s only half price of a DDR3 1333MHz ECC Server Ram) which is DAMN cheap! With HA and DRS, who really care about the reliability? Well Google is a good example using cheap hardware for building their data center globally.
  • The reason I choose Small Form Factor (SFF) is because it’s size of course and normally SSF has higher PSU 80 Plus efficiency and offers quieter experience.
  • Remember I wrote about my USB 3.0 experience with Poweredge R610 previously? Now I can finally use all those “thought to be wasted “ goodies, such as HighPoint USB 3.0 HBA Dual Ports with 5Gb/s individual port, plus my Hitachi Touro 2.5” 7,200RPM 750GB USB 3.0 external harddisk (somehow it works really fast with USB 2.0 as well), also I will get one more Lacie 2TB Minimus 5,900RPM for backup purpose.
  • I will also purchase a USB 3.0 IDE+SATA docking to transfer all my existing data over to the new PC.
  • Finally I will install VMware workstation 8 and test all the great stuff on it, like nested ESX, MacOS, ESX 5.0 and more.
  • For daily use, I only need Word and Excel, not even Access, so MS Office 2010 Home Edition is the perfect low cost solution for me. Even MS Office Starter should do most of the work, no worried about  opening PowerPoint as Microsft has a free Powerpoint viewer.
  • Same applies to selecting Win7Pro, I don’t need any of those additional features included with Ultimate, I could install Windows 2008 R2 Standard on this PC, but since the core is the same for Windows 7 and W2K8 now and Windows 7 supports more multimedia  devices, so why bother.

Update Dec 13, 2011

Btw, I’ve got my Optiplex 990 for almost a week now, I love the compactness and it’s really quiet even I placed it near my bed. Somehow, the internal 7200RPM 500GB boots up Windows 7 Pro in less than 15 seconds, this really makes me wonder if I still need to add the SSD caching (e.g., OCZ Synapse SSD). Anyway, I still ordered the special 2.5″ hard disk bracket for future upgrade which can fit 2 x 2.5″ SSD or  HD+SSD.

The other things is the default 4GB is enough for now, may add more later when I run VMWare Workstation 8 on top. Don’t have time to play this especially Xmas coming. :)

My 2.5″ USB 3.0 external 7200RPM Hitachi Touro is lightning fast around 116MB/s when testing with HDTune, even faster than the internal 3.5″ Western Digital Blue 500GB (about 105MB/s), comparing to my existing PIII 33MB/s ATA  (actually 12MB/s tested), this is almost 10 times more). Again the nice thing is I choosed that cheap Syba USB 3.0 card instead of Highpoint again because it doesn’t require external power, and 990SSF only has two SATA power cables which I will use for the above two 2.5″  disks later. Of course there is SATA split cables, as I don’t want to complicate the cables and reliability is another reason.

IMG_5706

Last but not least, the integrated Intel HD 2000 Display Port to DVI works perfectly with my old Dell Ultrasharp 2007FP (somehow Dell still sells it even now), it can output 1600×1200dpi sharper than ever, I can finally enjoy 1080p HD MKV movie and I noticed the CPU usage is only 2%, crazy low!

Update Dec 28, 2011

Finally received my 2.5″ HD Kit from Dell after the holiday. I have to say it’s a very hard to find item, took me a few days to google and talked to my sales in order to locate this Kit set. My advice is to order the complete Kit Set, not invididual parts, as it includes many extra items such as SATA split cable, SATA  cable, 4 screws (why 4 instead of 8? well, Dell expects you to use the 4 screws from original HD, that’s why this kit is called Extra Parts not Replacement Parts) and one more blue plastic HD holder, so R494D alone is not enough.

Update Jan 19, 2012

There has been a very strange problem with my Optiplex 990 SSF recently, it will simply power on itself automatically. I’ve searched around and found nothing, not even local Dell support was able to solve this myth.

Finally, I was able to locate the root of the problem, it’s related to Intel vPro or AMT (Active Management Technology) and the auto power on problem has nothing to do with BIOS setting or particular the WOL  setting.

By default Intel vPro has it’s own WOL and my PC is connected to an always-on fiber modem, so probably it received a WOL packet from the Internet. You can refer to AMT mannual for more information.

The solution is simply disable AMT for the time being (btw, the default password is “admin”) and I shall study more regarding vPro and how to use it and how to avoid such thing happen later.

Update Jan 30, 2012

The PC turns itself on problem continues and I tried one more thing to disable NIC with PXE and hope this will solve the problem completely.

Update Mar 14, 2012

The previous mysterious PC automatically turn on issue has been solved for sure, now it’s time to due with overall noise reduction.

After some research, I’ve figured out the most possible noise emission is from the main system fan (8cm fan), although the 1500RPM fan itself is already a better than normal quality, it still produces a noticeable amount of noise pollution.

So what you may have already guessed, yeah! Pull it OFF! Dangerous to do? Not really! It’s because the CPU has it’s own passive heat sink with fan, power supply never really pushing to 100% as my PC is mainly used for browsing the net, daily word processing as well as watching some HD movies.  The part needs the most cooling is RAM, after running for 1 hour with all sorts of activities, HWiNFO shows RAM merely went over 30C and hard disk also stays below 35C, that’s why I conclude and convinced it’s safe to do so.

If I want to reduce the noise further, the default 3.5″ 7200RPM hard disk will be my next target, simply by replacing it with a 2.5″ 5400RPM or SSD will make my Optiplex 990 SSF almost completely silent, but since my Dell carries 5 years warranty, I will probably let go on that option.

Finally, another big advantage by disconnecting the main 8cm system fan is reduction in dust pollution,  my 990 SSF was like a dust sucking machine before, and it’s no longer the case, um…I wonder how come main stream Optiplex 390/990 doesn’t come with a dust filter like Optiplex XE?

Update Mar 20, 2012

I’ve decided to put back the fan as it’s not a good idea after all, as the hard disk went over 40+ degrees after running for a few hours.

Update Jun 10, 2015

The biggest problem with Optiplex SFF is dust! Searching for that official dust filter for Optiplex for years in vain, ending up doing my own, simply cut a piece of water filter material for fish tank (9.5cm x 7.5cm) and put in front of SFF’s main fan. That’s it, it does the job beautifully as I’ve been running this configuration for the past 2 months, bulletproof, it works!

ASP Upload Hacking and PHP Spam Mailer

By admin, November 27, 2011 1:47 pm

I noticed the outgoing traffic of my email gateway has almost doubled over the past two days. There were thousands of spam mails using the default PHP email account (s285@domain.com was the default email account configured in PHP.ini, this helps a lot in tracking back which server is sending the spam) connecting from the Relayed dedicated server.

s285 is the relay dedicated server that’s been sending spam though our gateway and there are more than 50 sub sites on it, so to find out which sub site got infected spam mailer seemed impossible at first.

By searching thought which php file was modified in the past week, I was lucky to locate only a few, and by examining the file name (normally those hacking robot or mailer has blizzard names), I found one strange php script named 9024.php, tried to run it from the web page shows nothing, opened it with notepad, found it’s a PHPMailer using URL string as the parameter.

Then I simply removed it, but wait, how did it get uploaded in the first place? Well, client is running ASP and I asked if they have any upload function, but it turns out they have no idea at all  and I have no time to search through 200+ ASP scripts.

So the quick solution is to disable PHP function for this site.

Case closed. MAMAMIA!

p.s., Btw, I have a feeling that PHP hacking scripts are gaining a lot of ground in the past 2-3 years. One of the most interesting case I’ve came across that I’ve seen DDOS PHP script utilizing UDP and use URL string as the attacking parameter, I must admit this is simply genius indeed!

Hotwheel Elite Ferrari F355 Berlinetta

By admin, November 23, 2011 11:47 pm

Finally, Hotwheels will release its Elite version of F355 soon. For those who missed UT’s full series of F355, now it’s the chance. Somehow, I still think UT’s F355 shape is the most accurate one, especially the tail.

There will be three most popular colors for the Elite version: X5477 (Red), X5478 (Black), X5479 (Yellow).

可能是史上最貴的一次杭州菜

By admin, November 22, 2011 11:44 pm

今天是個特別的日子﹐去了本地杭州菜老字號“天香樓”慶祝﹐地方不難找因為之前經常經過。

前晚還特別做了事前研究﹐所以心裡大概有了個菜單。

80幾年的老鋪果然很有味道﹐我特別喜歡這裡六七年代的感覺。小店只有7張台﹐大概20來個客人加上幾個員工和老闆娘。

天香樓的陳年花雕酒果然香氣撲鼻﹐新來的店員還很有心地問我們要不要先暖酒才上。這次服務態度很好﹐很友善﹐跟幾年前第一次5分鐘不到就離座的不愉快經歷截然不同﹐那次可能是個持老賣老的開國員工吧。

我小時候最喜歡吃東坡肉﹐曾經試過找遍西湖邊的各大名菜館子﹐為的就是吃到最好的東坡肉﹐當年第一的居然也是天香樓﹐當然香港的這間才是老祖宗字號。

天香樓最出名的蟹粉雖然好吃﹐但沒傳說中那麼“犀利”。

天香樓的價錢也和其食物質量之高完全成正比﹐一年才一次﹐沒問題啦。

倒是今晚的膽固醇完全超標了﹐達到爆燈指數。

最後還巧遇蘇民峰師傅和女友在鄰桌用膳﹐真人跟電視上差不多。

Veeam’s Magical Ultility Extract.exe, Restore without the Original SQL DB

By admin, November 21, 2011 3:11 pm

Yes the VBK file created by transform process at the end of the week/month is enough to recover the latest VM state.

You can even extract that VBK without Veeam server present. We ship a tiny extract.exe tool (look for it in the product installation folder). No matter which media you use to backup your VBK files, just remember to put this tool there as well, and you will be able to restore data from the backup file even in 10 years from now – provided that media is still functional.

You can restore whatever restore point with the VBK. There should be some more information, such as syntax, if you do a find for “extract” in our B&R Users Guide. (Page 97 & 98)

Even if you lost the SQL backup, you could fire a new Veeam installation up (which takes less than 5 minutes) and do “Import Backup” and import your vbk/vrb/vib files and restore from those if you need other restore points.

The DB information is more about holding your job information and making sure your jobs run, you can import the data needed for restores from the files themselves. :)

So in other words, we  really don’t need to backup Veeam SQL data and send to DR site as this extract.exe tool will be enough even we lose the whole production site. All we need is the latest VBK file.
