Thank you for the insight & I completely agree with you will be much faster.

Grant in regards to the speed I am not sure there will be any increase as the hard drives are only 7200 rpm, in saying this I do not know what speed the drives are we are currently using.

The areal density of the new drives is much, much, much higher than the older ones, which means even for the same rotational speed their minimum & maximum data rates will be much higher.
Also being in a single enclosure, with much newer hardware (and more RAM for caching), the overall performance should be significantly better.
An All Flash Array would be better still (probably by an order of magnitude or more), but the cost of one with the same storage capacity would be considerably greater.

. . And that was in effect the new server which has died on Beta, Muarae2, all SSD drives.

Until the write/rewrite wear, cost and size factors have been eliminated then a mechanical drive is still the best outright bang for buck solution still under ideal conditions. ;-)

Cheers.

I haven't seen ANY post-mortem report on muarae2 over at Beta. What have you heard? All I heard was they had a problem with the database. Not any specifics.

The RTS is building and the out in the field is dropping. The greedy server isn't handing out WUs right now, even though it has some. I know at some point the dam will break and the WUs will flow, but I'm curious what coding bit is causing this hoarding.

edit: and just after posting. I get a bunch of WUs.

Posting about a problem often fixes it immediately

Unless the RTS row (or any row, really) is showing "As Of" 0 minutes, the data really doesn't mean much. Right now, it's at 9 minutes behind. Also, the fact that there is a lag time itself probably indicates other higher priority processes are hogging the available processing capacity or, at the least, too busy to respond with real times or numbers.

---

The server stats page only updates about every 15 minutes, so 9 minutes is between updates, so no need to worry about that.
But the RTS is perilously low at about 6000, and a creation rate of only 25 per second.
What is "interesting" is that the master database is running at about 1600 queries per second, which is pretty close to highest I've seen.

. . When it first went down I am sure I read there was a problem with one of the drives that corrupted the database. Not heard anything since ... Things happen here in Astronomical time, everything takes light years :) Sorry, I'll put that one back in the bad jokes box.

:)

P.S. I am still waiting to process any Parkes data.

When it first went down I am sure I read there was a problem with one of the drives that corrupted the database.

All it said was that there was a database issue. No indication of what that issue was, or how it was caused.



Edit- here it is,

The file system containing the beta project uploads directory is having problems, so beta is down until further notice.

So it could be hardware (the drives, memory, power supply, motherboard, BIOS etc, etc, etc) or software- the OS (a patch or update or a configuration change that borked things).

That is why I posted the question in response to the quote that the new SSD drives had all failed and that only spinning storage was reliable.

I questioned whether that statement was true when AFAIK there had never been any statement of ANY hardware failure. We just don't know what went wrong.

And as far as I'm concerned Stephen . . . your joke CAN be pulled out of the box as it is very relevant.

Stephen, don't put that poor joke away. It was "Astronomically" funny....

Sorry, I just have not had time to figure out what has gone wrong with the beta SSDs. It could just be a file system problem. Or it could be worse. Hopefully this coming week I'll have a chance.

Thanks for the update.

Pretty sure it's been that way for a while now, but just noting time & date to check again in an hour or two.

. . I don't believe you owe us an apology. Anyone who has been taking part in this project for any length of time and fails to appreciate that you guys are pretty busy just has not been paying attention. It just helps to grumble a little ... :)

. . BTW how is the Parkes issue going ? ...

It's Sunday Morning, and it appears the Server has checked out. I can Upload, but, all machines can't Report and Fetch work.
It's going to be the coldest night of the Year tonight, and I can't get work.
The results received is nosediving.... Results received in last hour = 93,016
