[TOMT][GAME][EARLY2000s] an old 3D PC disk game that had the polygon style where you command a large base and can send out AI units of tanks, vehicles, and helicopters to fight against an AI base that does the same.

The game played as you summoning all sorts of vehicles that would go out and follow a path to the enemy base and fight enemy vehicles that the main AI base would spawn. Your team would be blue and the AI team would be red. The game visuals were very basic. You could see the grid of the terrain as simple mesh with the polygon edges visible. I remember one mission where you had to protect I think a nuclear station from being destroyed. If it was destroyed it would let out a slow moving shock wave that would destroy your base instantly when it hit. You were able to teleport the main base a short distance every once in a while but it would just put the wave in front of you if you tried passing the wave. You could take command of a few turrets on the main base or take command of one of the vehicles on the field. I can't remember what resources were used in order to summon more vehicles, I think it was just generated over time. The only names I can remember of the vehicles were two helicopters called a "wasp" and a "hornet" the wasp was a quick moving scout helicopter that I don't think had any guns and the wasp was more like an Apache with multiple guns but was slower. Each level was selected on a menu that looked like a big map of the world (but not of our world) with different continents and regions on them that lit up when you selected them. beating one unlocked the next level in line. It had a main color scheme of blacks and blues for the map. My uncle had burned the game onto a CD so I don't know what the cover looked like or remember the name. This is the most I can recall of it.

[O] [US-PA] Philly Storage Unit Sale on Saturday 4/24 - Dell Servers, Cisco Switches, EMC Disk Arrays, + a bunch of other random gear

Hi r/homelabsales, an IT consultant I bought a server from several months ago is having a storage unit sale that may interest this sub. I've done some contract work for him recently and volunteered to post about it here since he's not on reddit.

I've included a link to an Imgur album with pictures of some gear that will be there, but there's an entire (large) storage unit full of stuff that I couldn't include. I'm just posting to let people here know about this, so you'll have to show up and talk to him to find out details about specific items or pricing. That said, I have seen the storage unit and some of the gear, so I'll do my best to answer any questions in the meantime.

Some of the stuff I know will be there:

  • Dell PowerEdge R910s
  • Dell PowerEdge R730s
  • Dell PowerEdge R210ii
  • Misc. Dell rail kits
  • EMC disk arrays
  • Cisco 3750? switches
  • Cisco 4948E-F switches
  • Cisco MDS 9148S switches
  • Cisco DS-SFP-FC16G-SW SFP+ transceivers
  • Used 2TB 3.5" SATA HDDs
  • Used 2.5" SAS HDDs of various sizes
  • (Lightly) used 800GB SAS SSDs
  • Misc. Riverbed + Avaya network appliances
  • Lots of VOIP phones + accessories
  • Random stuff like FLIR cameras

Link to Imgur album of gear: https://imgur.com/a/EN0siTJ

Open House Details:

From: ~ 9:00 AM - 1:00 PM on Saturday April 24th, 2021

Address: Extra Space Storage - 2035 Chemical Rd, Plymouth Meeting, PA 19462

Edit: Feel free to simply show up anytime within the above time-frame. You'll be able to see the open storage unit from the entrance of the facility. If the gate isn't open, wave down someone at the unit to be let in. There may be multiple people browsing at any given time, so please wear a mask and be mindful of basic social distancing guidelines.

For spinning NTFS disks, it appears that larger allocation unit sizes are faster than the default 4kb

https://i.imgur.com/Su4WtDw.png

Started all the plots via the gui with default memory/thread settings at roughly the same time, starting from the 4kb to the 64kb allocation size disks. Using an intel i7-8700k 6 core processor with 12 threads and 32gb ram. All disks connected to the motherboard sata headers. Same brand 2tb 7200rpm disks.

It appears from my initial run, that larger cluster sizes are faster by roughly 3%. There might be a diminishing return after 32kb, but I only have done a quick test so far.

I selected the 64kb disk before the 32kb disk when generating the plots, but it appears that the 32kb disk might be slightly faster than the 64kb disk.

So just a slight experiment with preliminary results that I hope can open up further efficiency.

TLDR: I think larger allocation sizes are roughly 3% faster than the default.

Why is the unit disk so widely studied in complex analysis?

Many results in complex analysis involve the unit disc, or things are simply done on the unit disc. Why is this? Is it because of the Riemann mapping theorem? Due to there being a bijective holomorphism between simply connected subsets of the complex plane and the unit disc is it just simpler to consider the unit disc?

[FS][CAN-BC] North Vancouver Netapp DS4243 Disk Shelf (two units) $400 each

I have TWO Netapp DS4243 disk shelves for sale, $400 each. They each hold 24 SAS or SATA drives (interposers are available for SATA drives) to connect to an external SAS equipped server or pc. I've been using these with a Dell Poweredge R420 for the past year, prior to that they came out of a datacenter in Alberta.

Both controllers are included though you can use just one. At least two power supplies are included. They are a very easy way to add additional drives to a server or pc you may already own. After initial power-on the noise is tolerable in an office environment. Trays and screws are included but disks are not. If you are looking for hard drives I have a few variations that I'm looking to get rid of for cheap.

I will also include one QSFP to SFF-8088 external SAS cable for each as they’re not compatible with anything else I own. They’re about $50 each new.

If you know about these units, they are pretty tough to get in Canada. I'm selling mine since I've moved to higher density (fewer) disks in my FreeNAS setup. Local pickup preferred, they are extremely heavy and would cost a lot to ship safely.

ELI5: Why are there disks, USBs and memory cards with more storage than others of the same kind of a storage unit?

I have always had the doubt about how it is possible that a 4GB USB memory can be the same size as a 256GB one. How is it that an SD memory can be so small and be 256 GB, and at the same time only 2GB.

Why are there so many types of storage units? Why does a computer have to use a hard disk instead of an SD memory of the same size?

Replacement disk says: NOT READY, Logical unit not ready, initial

Two weeks ago, on my FreeNAS unit one of my disks failed, so I sent it to HGST for a warranty replacement. After I received the replacement disk (Same type, same size), I installed it but could not replace the degraded ZFS pool. It seems like the device is not fully recognized by my system and I am clueless. The device cannot query its size. I also tried different slots in the chassis, same results. When I enter setup on boot and switch to the SAS controller settings, it shows no information about the newly added device.

Does anyone here have an idea?

Mainboard: Supermicro X11SSL-CF
SAS Controller: LSI SAS3008 (Onboard)

Like the title says - I added a new 3TB WD Red disk to my trusty old DS411j, and started repairing the degraded storage pool. I'm not surprised it's taken a while, but I am skeptical to the fact that DSM is unresponsive, and that none of the HDD lights seem to be doing anything.

The unit does respond to ping.

Should I just wait longer? Reboot?
