Re: Acquired Indigo2 IMPACT, My first (working) SGI+Questions

anyone wants to pimp the R8k here... Ah, the performance level of the Cray Y-MP in a system based on a single chip. Floating point performance that is, it's not much good at anything else. It also has a reputation for being somewhat fragile. And of course it never worked with IMPACT graphics... Any...

Experience with Xyratex RS1600 FC arrays? (2Gb/s -> 4Gb/s)

I've got an SGI TP9100 JBOD. That's a rebadged Xyratex RS-1600-FC2 16 bay FC JBOD. Thing is, it's filled with 4Gb/s disks (Seagate 15K.7) and I've got 4Gb/s FC interfaces on my Tezro. The only thing holding me at 2Gb/s are the interface cards of the RS-1600-FC2. Xyratex used to make these things in ...

Re: doomed - use! HTTPS Everywhere - google explained why

Possible, but a more likely conclusion is that the root the cert chains to isn't in Fx3.0.19. (I don't remember.) Firefox 3.0.19 is 8 years old. Root and intermediate certificates last longer then regular certificates, but a significant number (if not: most) of them must have expired by now. It won...

Could this be the work of the Great China Firewall?

Re: doomed - use! HTTPS Everywhere - google explained why

HTTPS is just an extortion racket pushed by certificate authorities. Letsencrypt ended that two years ago. It's a matter of seconds to install, and renews certificates automatically. I don't get what the fuss is all about, to be honest. I run techpubs.jurassic.nl, which comes in both flavors (HTTP ...

Re: Dat compatibility question

Here's what /var/sysgen/master.d/scsi looks like on an IP26 PowerIndigo2 running IRIX 6.2. I can provide the file from IRIX 5.3 as well. There might be an extra field in the description structs but overall it looks very similar to 6.5: *#ident "$Revision: 1.37 $ * * SCSI * *FLAG PREFIX SOFT #DE...

Re: your latest purchase

I just finished low level formatting the first of qty 17 Seagate 15K.7, 450GB FC disks. Bought them for less than 4 bucks a piece. This will give me 16x 450GB FC goodness in my TP9100 array (and a spare) :mrgreen: They come from some big SAN of course so they were formatted 520bytes/sector. I'll see...

Very cool!

It might not even be a switching power supply, but using a transformer. I had a similar experience with a terminal port server (EL16), made shipping quite expensive :(

Re: FireWire/800 to SATA | FC (optic) to SAS/SATA

Re. FireWire: unlike USB, FireWire doesn't need hubs to create a topology of nodes. That's because most FireWire nodes have more than one (often 3) ports. Usually, every disk, host adapter, webcam etc is one node. Every node can then be connected to 3 other nodes, and together they form the FW topol...

Re: Homebrewed 128Mb SGI O2 RAM

1. It could be there are not enough address lines wired, on the mainboard or to the DIMM sockets. 2. At some point if you keep enlarging the RAM, it's going to overlap something else (hardware registers, PCI, ...) and you will crash. That's what happens if you install a third 512MB kit in an IP28 In...

Re: If there's something strange in your FW/400 ...

I'll go digging and report back if I find it. As it turns out, there are no FireWire / SPB2 related patches for IRIX 6.5.30. So it was probably XFS, possibly this one: Bug #957285 - tlbmiss in xfs_bmbt_get_blockcount while running fsr Fixed in the XFS rollup patch for IRIX 6.5.30 (patch 7214 > 7229...

Re: Restoring an Indy, have some questions

I've had good luck buying Sun branded 72Gb SCA drives. They are quiet and run cool. Those older 10k rpm drives would cook an egg. Just look up the specs of the Seagate / Fujitsu / whatever type disk. Look for 'FD bearings'. Not only are they more quiet than the older bearings, they age better too. ...
