I'm trying to get into the world of home file servers (or an NAS, I'm not really sure what the difference is) and there's a lot of information on how to start. There are a few things that I would like to see, get a feel for, and hear other peoples' opinions on.
What are some of the best... (5 Replies)
Hi all,
We have a disk array that has the boot drive on an OCZ SSD on a PCIe card. Well, the motherboard died and we got a new motherboard. We moved the controllers, NICs, etc, to the exact same slots on the new motherboard, except now it won't boot. I guess it doesn't recognize the OS on the... (1 Reply)
I have an upgrade path in mind for a new computer that will be stocked with a 2TB SATA 300 hard disk. This is a choice based on information that SATA 300 is not necessarily faster than SATA 600. The upgrade path in a year time or so would then involve the purchase of an SSD that would contain the... (4 Replies)
Hello everybody,
I need to connect a laptop 2.5 SATA hard drive to a Desktop board (which uses 3.5' SATA hard drives). I've tried the connectors and they fit excellent in the 2.5 SATA connectors.
The problem is that the laptop hard drive uses 5v and the PC's power source sends 12v. So, my... (4 Replies)
trying to setup a sata drive using a sata to scsi adaptor
I have a sata 1TB Deskstar that I had setup before and during shipment from a facilty to another, the disk failed. The handling was not great, lots of throwing boxes, etc. I have a new disk from Hitachi (thankyou Hitachi) anyway, I don't... (1 Reply)
i have a network drive (samba) mounted on to my PC and also i have SSH client on my machine. however i need to run applications/commands on a unix server from the middle of a different executable(windows compatable one). so i need to connect to the unix server from SSH through the... (1 Reply)
SPEED(1SSL) OpenSSL SPEED(1SSL)NAME
openssl-speed, speed - test library performance
SYNOPSIS
openssl speed [-help] [-engine id] [-elapsed] [-evp algo] [-decrypt] [-rand file...] [-writerand file] [-primes num] [-seconds num]
[-bytes num] [algorithm...]
DESCRIPTION
This command is used to test the performance of cryptographic algorithms. To see the list of supported algorithms, use the list
--digest-commands or list --cipher-commands command. The global CSPRNG is denoted by the rand algorithm name.
OPTIONS -help
Print out a usage message.
-engine id
Specifying an engine (by its unique id string) will cause speed to attempt to obtain a functional reference to the specified engine,
thus initialising it if needed. The engine will then be set as the default for all available algorithms.
-elapsed
When calculating operations- or bytes-per-second, use wall-clock time instead of CPU user time as divisor. It can be useful when
testing speed of hardware engines.
-evp algo
Use the specified cipher or message digest algorithm via the EVP interface. If algo is an AEAD cipher, then you can pass <-aead> to
benchmark a TLS-like sequence. And if algo is a multi-buffer capable cipher, e.g. aes-128-cbc-hmac-sha1, then -mb will time multi-
buffer operation.
-decrypt
Time the decryption instead of encryption. Affects only the EVP testing.
-rand file...
A file or files containing random data used to seed the random number generator. Multiple files can be specified separated by an OS-
dependent character. The separator is ; for MS-Windows, , for OpenVMS, and : for all others.
[-writerand file]
Writes random data to the specified file upon exit. This can be used with a subsequent -rand flag.
-primes num
Generate a num-prime RSA key and use it to run the benchmarks. This option is only effective if RSA algorithm is specified to test.
-seconds num
Run benchmarks for num seconds.
-bytes num
Run benchmarks on num-byte buffers. Affects ciphers, digests and the CSPRNG.
[zero or more test algorithms]
If any options are given, speed tests those algorithms, otherwise a pre-compiled grand selection is tested.
