  • LTO 2 tape performance in LTO 3 drive

    - by hmallett
    I have a pile of LTO 2 tapes, and both an LTO 2 drive (HP Ultrium 460e), and an autoloader with an LTO 3 drive in (Tandberg T24 autoloader, with a HP drive). Performance of the LTO 2 tapes in the LTO 2 drive is adequate and consistent. HP L&TT tells me that the tapes can be read and written at 64 MB/s, which seems in line with the performance specifications of the drive. When I perform a backup (over the network) using Symantec Backup Exec, I get about 1700 MB/min backup and verify speeds, which is slower, but still adequate. Performance of the LTO 2 tapes in the LTO 3 drive in the autoloader is a different story. HP L&TT tells me that the tapes can be read at 82 MB/s and written at 49 MB/s, which seems unusual at the write speed drop, but not the end of the world. When I perform a backup (over the network) using Symantec Backup Exec though, I get about 331 MB/min backup speed and 205 MB/min verify speeds, which is not only much slower, but also much slower for reads than for writes. Notes: The comparison testing was done on the same server, SCSI card and SCSI cable, with the same backup data set and the same tape each time. The tape and drives are error-free (according to HP L&TT and Backup Exec). The SCSI card is a U160 card, which is not normally recommended for LTO 3, but we're not writing to LTO 3 tapes at LTO 3 speeds, and a U320 SCSI card is not available to me at the moment. As I'm scratching my head to determine the reason for the performance drop, my first question is: While LTO drives can write to the previous generation LTO tapes, does doing so normally incur a performance penalty?

  • What LTO 4 drive to buy

    - by pplrppl
    Evan Anderson mentioned in another solution you could buy a LTO-4 (autoloader, 1 tape / day) - $4,566.00 (the discussion included total cost of tapes for a specific rotation.) but I don't know specifics on what he or you would recommend for the actual drive and if necessary controller. Show me a newegg URL or CDW, Dell, or HP, or whatever your favorite vendor would be for your solution if you don't mind looking it up or just give me a brand and a model number and I'll be glad to do the leg work myself. I currently have on have on hand an external LTO 3 drive that uses LVD SCSI interface (and thus have a controller card that has an external LVD SCSI connector). If that card isn't sufficient to interface to a LTO 4 drive let me know. http://www.fujifilmusa.com/shared/bin/LTO_Overview.pdf shows minimum tape speeds for LTO4 and other LTO formats. It looks like the IBM LTO4 actually has a lower minimum speed than the IBM LTO3. Either way my average server is too slow to feed LTO3/4 without shoeshining so I'm looking for a drive with a low minimum write speed. If you trust the PDF from 2008 that makes my choices IBM LTO 4 full height IBM LTO 4 half height HP LTO 4 half height but presumably there are other options out there that weren't mentioned in the fuji PDF. Again I'm looking for a specific recommendation on a drive to buy (and the controller if needed).

  • LTO(4) tape shelf life estimation?

    - by emilp
    LTO tapes, Maxell in this case, are often marketed as having 30 years or more shelf life when stored under "optimal conditions" Is there a way to get a good estimation to the shelf life, given parameters such as relative humidity and temperature etc? Obsolescence of the tapes aside, is there a way of determining the impact to shelf life of any deviance from the optimal. In other words how many years are lost when storing say 1 degree above the specified range? regards Emil

  • Directly reading a LTO tape drive

    - by John
    On our server (M$ 2003) is it possible to directly read our LTO 4 tape drive and copy the entire ntbackup created bkf file on it to an external hard disk? (Is the tape backup even stored on a tape as a bkf file, I’m going off when we only used external usb HD’s.)

  • IBM LTO 3 Tape drive periodically going "offline"

    - by bruno077
    I have a problem with a LTO 3 Tape Drive. I'm using Brightstor ArcServe Backup software with Windows Server 2003. Sometimes, the scheduled backups will stop working and going into "devices" inside this software reveals that the Tape Drive is offline. The only way to make it work again is uninstalling the Tape Drive's driver and rebooting the server: Windows then auto recognizes and installs the required drivers and the Tape Drive works again. Has anyone ever encountered a similar problem?

  • What other tape manufacturers can I use in IBM LTO Gen 3 SAS Tape Drives

    - by timgws
    I have recently just got my hands on an IBM 3580S3V. I was just wondering if there are any other brands that I can use in this IBM gear? LTO media are usually manufactured only by EMTEC, Imation, Fujifilm, Maxell, TDK and Sony (according to Wikipedia). I am trying to determine who OEM's the IBM tapes, or if possible, a list of media that IBM supports. So far in my Google studies, I have only been able to see IBM as the supported media manufacturer (seeing as they sell tapes, I assume they don't want anyone buying media from competitors!)

  • LTO 3 tape drive needing repaired

    - by DO it all Paul
    We have an IBM LTO 3 tape drive that needs repaired and with the £400 price tag i'm having to shop around for quotes. My question is has anyone actually repaired one before and how was in done? The first error LED was showing a 6, then i cleared the mangled tape only for it to start flashing alternate 'o' on the 7 segment display, simliar to a half 8, flashing top to bottom and it would just flash away like that coupled with a flashing amber light. I tried a reset holding the eject button for it to show an 'r' the go back to flashing again as before. I checked the IBM solutions for the codes but this flashing isn't documented at all. Would be great if anyone had any experience in this area. Thank you, Paul

  • Compatibility of ESX 4 and LTO 3 with LSI2032 Dell Power Edge

    - by dbaur
    Hello, does anybody know something about the compatibility of an LTO 3 Tapedrive (PV HH LTO 3 400GB) attached to an LSI2032 SCSI-Controller? These devices are added to an Dell PowerEdge T610 Server which is listed in the certified Compatibility Guide. I can`t find any information for this controller and this tapdevice. Or are they automaticly compatible because they are options for an compatible Server? greetings Dennis

  • Internal LTO tape drive becomes hot

    - by claasz
    We use an internal LTO3 tape drive (HP Ultrium 920) in a PC (no particular server hardware) running Linux. The tape drive becomes quite hot - I don't have the exact temperature, but you may touch it for a second or two, then it hurts ;-) This happens when the tape has nothing to do (during reading/writing, it might become even hotter, I haven't checked that). Besides that, the system is working fine. Now I'm wondering Why does the tape becomes so hot? Is this something I need to care about? Is there something like a 'standby' mode for the tape? (I think it should not consume that much energy when it is not used)

  • Do I need to run a verfication on LTO tape backups even though the drives themselves perform verification as they write?

    - by ObligatoryMoniker
    We have an LTO-3 Tape drive in a Dell media library that we use for our tape backups. The article about LTO on Wikipedia states that: LTO uses an automatic verify-after-write technology to immediately check the data as it is being written, but some backup systems explicitly perform a completely separate tape reading operation to verify the tape was written correctly. This separate verify operation doubles the number of end-to-end passes for each scheduled backup, and reduces the tape life by half. What I would like to know is, do I need my backup software (Backup Exec in this case) to perform a verify on these tapes or is the verify-after-write technology inherent in LTO drives sufficient? I would also be curious if Backup Exec understands the verify-after-write technology enough to alert me if that technology couldn't veryify the data or will it just ignore it making it useless anyway since even if the drive detecs a problem I would never know about it.

  • Archiving to Tape

    - by Bruno
    This is not about backups, this is about archiving. For arguments sake lets say I have 2TB 7z file that I would like to archive to tape. I have 4 LTO-5 tapes ( 1.5TB each ). This may be a stupid question but what set up would I need that would allow me to drag and drop those files directly onto those 2 tapes and would automatically split the file accross 2 tapes like so: ------------------ | Copy 1 | | 1.5TB | ------------------ ------------------ | Copy 1 | | 0.5TB | ------------------ ------------------ | Copy 2 | | 1.5TB | ------------------ ------------------ | Copy 2 | | 0.5TB | ------------------ I just want to be able to specify which files go on which tapes as oppose to backups where the tapes just rotate. Thanks.

  • data protector red tapes

    - by Caesar
    I am using HP Data Protector A.06.11 in my organization, with HP EML E-SeriesEML library, with 4 drives using LTO-4 tapes, and i am having some problems. Yesterday I put 5 new tapes in the robot and formatted them. At that time, the robot got just those empty 5 tapes with empty space. (all the rest of the tapes are red, or with protection) Today in the morning after the night (1 backup run at night), and 2 of the new tapes are red (the properties are): Writes : 2 Overwrites : 1 Errors : 9 I format one of them, and check for each drive if the tape become red, no one of the drives do it. In the main pool properties, in media condition got: Valid for : 36 (months) Maximum overwrites : 250

  • Inexpensive degaussers or HDD shredders?

    - by Nicholas Knight
    I do a lot of work for a small cash-strapped business that has a lot of active hard drives, most are consumer-grade SATA of about five years of age, and predictably they are dying at an increasing rate, and a lot of the time they can't even be detected, let alone complete a zero-out cycle. Right now those drives are just being stored, but that can't continue forever. We've got a couple bad LTO tapes it'd be nice to deal with, too. There are very real security and legal issues that make dropping them off with someone who claims they'll be properly destroyed a gamble. I've looked around at degaussers and HDD shredders, and the ones that don't look like they come from some guy in his basement all seem to be $3000+, which is hard to swallow right now. Is there anything out there in the $500-1500 range that you would recommend? (Speed isn't a big issue, if it takes several minutes or even hours per drive, that's completely OK, we've only got 10 or so thus far.)

  • Ultrium 3 tape drive shoe-shining, 3Mb/s: and it's not the cable

    - by mowsala
    I have a HP 960 Ultrium 3 tape drive. Since I got it, (second hand, £90) I've been experiencing shoe-shining. Writing with tar in Linux, I average about 3Mb/s write speed. I've tried replacing both the SCSI card and the cable now, both of which made no difference at all. A curiuos observation I have made is that the write rate is not consistent. Sometimes it will write for over a minute without shoeshining, but more often, just a few seconds. I've also tried several tapes, different source drives, and even writing from Windows Backup, to no avail.

  • Circle-Line Collision Detection Problem

    - by jazzdawg
    I am currently developing a breakout clone and I have hit a roadblock in getting collision detection between a ball (circle) and a brick (convex polygon) working correctly. I am using a Circle-Line collision detection test where each line represents and edge on the convex polygon brick. For the majority of the time the Circle-Line test works properly and the points of collision are resolved correctly. Collision detection working correctly. However, occasionally my collision detection code returns false due to a negative discriminant when the ball is actually intersecting the brick. Collision detection failing. I am aware of the inefficiency with this method and I am using axis aligned bounding boxes to cut down on the number of bricks tested. My main concern is if there are any mathematical bugs in my code below. /* * from and to are points at the start and end of the convex polygons edge. * This function is called for every edge in the convex polygon until a * collision is detected. */ bool circleLineCollision(Vec2f from, Vec2f to) { Vec2f lFrom, lTo, lLine; Vec2f line, normal; Vec2f intersectPt1, intersectPt2; float a, b, c, disc, sqrt_disc, u, v, nn, vn; bool one = false, two = false; // set line vectors lFrom = from - ball.circle.centre; // localised lTo = to - ball.circle.centre; // localised lLine = lFrom - lTo; // localised line = from - to; // calculate a, b & c values a = lLine.dot(lLine); b = 2 * (lLine.dot(lFrom)); c = (lFrom.dot(lFrom)) - (ball.circle.radius * ball.circle.radius); // discriminant disc = (b * b) - (4 * a * c); if (disc < 0.0f) { // no intersections return false; } else if (disc == 0.0f) { // one intersection u = -b / (2 * a); intersectPt1 = from + (lLine.scale(u)); one = pointOnLine(intersectPt1, from, to); if (!one) return false; return true; } else { // two intersections sqrt_disc = sqrt(disc); u = (-b + sqrt_disc) / (2 * a); v = (-b - sqrt_disc) / (2 * a); intersectPt1 = from + (lLine.scale(u)); intersectPt2 = from + (lLine.scale(v)); one = pointOnLine(intersectPt1, from, to); two = pointOnLine(intersectPt2, from, to); if (!one && !two) return false; return true; } } bool pointOnLine(Vec2f p, Vec2f from, Vec2f to) { if (p.x >= min(from.x, to.x) && p.x <= max(from.x, to.x) && p.y >= min(from.y, to.y) && p.y <= max(from.y, to.y)) return true; return false; }

  • Tape Supplier in Canada

    - by JohnyD
    I'm not sure if it's kosher to ask.. but where can one purchase good quality / well priced backup tapes within Canada, online? I'm asking because my current vendor, DataWrite, has sent me bad tapes for the 3rd time in a row. I have no idea where they get their product but when I put an order in for 20 tapes and 2 cleaning tapes and I have to call them up 4 times over the next 2 weeks, I expect those tapes to work. Well, like I said, this is the 3rd batch that I'm sending back and we've been dealing with them exclusively for well over 5 years so I thought I'd ask the pool of knowledge. I'm currently looking for DAT72 tapes but soon will be looking for LTO-3 and LTO-4. Thank you

  • makefile pathing issues on OSX

    OK, I thought I would try one last update and see if it gets me anywhere. I've created a very small test case. This should not build anything, it just tests the path settings.
