RE: Storage space overheads!
by Bokkelkamp, Ernst 31 Jul '06

31 Jul '06

"I wish NetApp had Raid5, this could have eliminated some issues like using 2 dual-parity drives." Why ? Somehow I get the impression, looking at the last few messages, that the majority does not understand raid_dp and the differences to raid_4. For practical purposes raid5 + some filesystem is "like" raid4 + wafl, particulary when you compare the data : parity disk ratio. Comparing raid4 to raid_dp you should notice that raid_dp provides a better protection with equal overhead when used on large volumes/aggregates. Large aggregates use the same number of parity disks but the raid_dp parity disks protect twice as many data disks compared to raid4. Sometimes the cost of one drive can be justified to provide additional protection on small volumes/aggregates, if not than you can always use raid4 instead. Btw: there is an interesting document on WAFL in the knowledgebase - it is definitely worthwile to understand the principles behind WAFL to understand the benefits of raid4 and raid_dp.

Marge... I'd much rather have RAID-DP than RAID5 - RAID-DP affords for faster read\write access and the ability to lose TWO drives without losing data (raid5 can only lose one). If you feel strongly about not wanting to use multiple disks for parity, use traditional RAID4 - still faster read\write access when compared to RAID5, but obviously you won't have as much resiliency to failure. That will surely boost your usable space as well.

Dear Friend, I work as the Head of Fund Manager Executive with Fidelity Investment UK, the World Leading Investment & Fund Management Institution based in UK/Channel Island. I have an Investor under my portfolio with a closing balance of $42.870m as his first initial deposit. This Investor died three years ago leaving no WILL or AUTHORIZATION for re-transfer of his Investment and its proceeds to the INHERITOR.I have personally carried out an Investigation on the subject matter that took me 12 months to finalize and was made to understand that the Family or Relatives of the Investor knows nothing about his Investment with Fidelity and none have any records of all his deposits and investment with us leaving an avenue for claiming of the said funds with its accrued interest on presentation of a trustworthy person that can stand as the INHERITOR to the deceased . If you are interested, I can present you as the INHERITOR with proper documentation that will qualify you to have the funds claimed and on doing this, our establishment will not question the release of the funds to you as I will make sure that we comply with the laid down rules and laws of claiming the Investment of a deceased Investor in our Establishment. Our sharing ratio will be 50:50.Please contacted me for more detail breakdown if interested. Looking forward to hearing from you shortly. Sincerely. Mr.John Fisher. www.fidelity.co.uk

Dear Friend..............Important information please replay
by Tomas Traore 29 Jul '06

29 Jul '06

Dear Friend, I sourced your e-mail address from the internet directory as we have not previously known each other. However, every relationship begins one day I am Eng.Tomas Traore, the site inspection director with the ministry of works and construction and I work directly with the Minister in charge of the Ministry here in Republic of Sudan. I awarded a contract for IRRIGATION to a Portuguese firm worth several millions of dollars a few years ago. In the course of executing the project the firm discovered large gold deposit in one of the construction sites. Being the site director I collaborated with the firm in the mining of the gold on a mutual agreement to share the proceeds out of which I got a share of $16.4 million dollars. As an ordinary director and a mere civil servant in this small war torn country, I cannot introduce this funds into the banking system here considering my meager monthly income as well as the code of conduct guidelines regulating civil service here in my country, Sudan. Presently Sudan is engulfed in a civil crisis and as this crisis intensified by the day, I decided to leave with my family and succeeded in also moving this fund out of Sudan under diplomatic cover. I am presently out of Sudan I therefore solicit for your co-operation to take delivery of this fund into your custody for any profitable investment that will be mutually beneficial. I will be able to arrange all necessary procedures to ensure smooth movement of this funds until you are in control of it. Please let me know if you are interested by return mail and also include your full names and contact telephone number to enable me call you. I will provide you with my contact telephone and where I am presently as soon as you indicate appreciable interest to deal Please contact me on this email address (tomastraore2000(a)terra.com.ve). Thanks and God bless Regards, Eng. Tomas Traore

dont let me down
by Marie Roberts 29 Jul '06

29 Jul '06

Hello, You may be surprised to receive this mail, as you read this, don'tfeel so sorry for me because I know everyone will die someday. My name is Mrs. Marie Roberts, a business woman in London. I have been diagnosed with esophageal cancer which was discovered very late due to my laxity in caring for my health. It has defiled all forms of medication right now and I have only about few months' to live according to medical experts. I have never particularly lived my life so well as I never really cared for anyone not even me but my business. Though I am very rich, but I was never generous, I was always hostile to people and I only focus on my business as that was the only thing I cared for in my life. But now I regret all this as I now know that there is more to live. Though I am very rich, but I was never generous, I was always hostile to people and I only focus on my business as that was the only thing I cared for in my life. But now I regret all this as I now know that there is more to life than just wanting to have or make all the money in the world. I believed when God gives me a second chance to come to this world I would live my life in a different way from how I have lived now, but now that God has called me through this way I willed most of my properties and access to my immediate and extended family and as well as few close friends. I want God to be merciful to me and accept my soul and so with that reason I decided to give alms to CHARITY ORGANISATIONS, as I want this to be one of the last good deed I did on earth, so far I have distributed money to some Charity Organization in countries like India and Sudan. Now that my health has deteriorated so badly, I cannot do this myself anymore. I once asked my family members to close one of my accounts and distribute the funds which I have there to CHARITY ORGANSATION in Rwanda and Pakistan; they refused and kept the money to themselves.Hence, I do not trust them anymore, as they seem not to be contended with what I have left for them. The last of the funds which no one knows of, is the cash deposit in one of the banks here.I want to know if you can be of good help to dispatch these funds to CHARITY organizations. I have set aside 20% of the total amount $1,500,000.00 One million five hundred thousand dollars) for you and your time and patience for carrying out this duties.This means you will keep $300,000 (three hundred thousand dollars) for yourself and donate the rest to any charity organisation. May God be with you as you have decided to take a bold step to heal the world with me or even in my demise. If you can give me this assistance, you can send an email to my lawyer who has all the legal documents covering this transaction. He would give you more details. His name is Barr. Larry Smith and his email address is: ( larrysmith36(a)aim.com ) He would guide you through receiving the funds. Best Regards, Marie Roberts

My dear, Before I introduce myself, I wish to inform you that this letter is not a hoax mail and I urge you to treat it serious.I am a Director in Procurement Department with Petroleum Ministry.I obtained your email while searching for a reliable person,who could assist me in receiving transfer of a supposed contract awarded funds. This fund came as a result of over estimated contract awarded sums executed by foreign contractors in the Petroleum Ministry here in Nigeria.The concerned Ministry has approved these over invoiced funds for payment. The contracts which the over invoiced sums was created from has been executed and commissioned.What I am about to receive now,is the over estimated funds which was added during the process of obtaining the contracts for my own interest.This is a normal deal that goes in my Ministry by top officials. All I want from you is to receive these funds on my behalf as a Sub-Let Company, because as Government Official I cannot collect the funds directly from my Ministry,neither I am allowed by Law to operate/ run foreign bank accounts.If you are trustworthy and can assist me in receiving the fund,do not hesitate to respond back to me immediately. Looking forward to hearing from you soonest. Best regards, Engineer Frank Bello

We have a R200 which has 168 ATA drives. I expected a high failure rate on these as ATA drives are not rated for continuous duty. I have been surprised, and pleased, that failure rate has been very low - perhaps 3 drives in a year. Not sure about the SATA. The way I am moving is to use (S)ATA for my NAS (user shares) and FC drives for hosting my iSCSI LUNs.

To summarize, the following is true (i.e., about storage sacrifice): - Disk are right sized (realigning size in blocks from different vendors...eg., for 72GB we get 68GB) before using by NetApp. - dual parity (2 disks on RG of 16 => 14D+2P) - spare disk/s - WAFL & RAID overhead (~ 5%). - aggr reserve 5% default - vol snapshot reserve 20% default - for LUNs: 50% for base snapshot + extra space 20% of remaining data space - user data should always be below 90% to avoid performance bottleneck and defrag issues. That's sounds bad to me, but if you all feel to be true then its must be a solution. How about putting SATA disks on the primary filers to save costs? Whats are the problems in replacing FC disks with SATA? Whats record about SATA disks, I heard they are terrible? (Failure rates is abnormal) Thanks again for feedback. Marge.

RE: Storage space overheads!

WAFL and RAID overhead is not 5% - it's 10% off of the top (and it's specifically WAFL overhead - the RAID overhead comes in the parity disks). The 'extra space 20%' for snapshots with LUNs will vary based on the application and the snapshot retention. It may be 0% in some cases, or as much as 100% in others (this is the 'it depends' part). That is not bad if you consider that every disk subsystem has RAID overhead (NetApp is no more than Hitachi or anyone else) and that snapshots are backups - if you didn't need snapshots, there would be only the 10% overhead. You can put SATA in place (the 3000 series supports it natively, even on boot volumes), but there are serious performance risks with doing so: SATA can do about 50% of the IOPS of an FCAL drive for the same amount of latency. What this means is, if you need to get 150 IOPS per disk, SATA will have double the latency of FCAL. That may not impact your application, or it may - this is where the analysis needs to focus (bad for Exchange or any other OLTP database, but probably just fine for data warehousing). SATA does have higher failure rates than FCAL - this will probably change over time, but expect SAS to be the 'new hotness' - FCAL goodness, with SATA ease - and 2.5" drives are going to be the new thing as well.. time will tell if NetApp will go this direction or not. Hope this all helps, Glenn -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of margesimpson(a)hushmail.com Sent: Thursday, July 27, 2006 10:00 PM To: toasters(a)mathworks.com Subject: RE: Storage space overheads!
