Hard disk drive and RAM memory - Dynamic Power Management

From what I have seen there is a pretty good support for dynamic power management in the both Windows and Linux when it comes to the CPU (scaling frequency so as to reduce energy consumption). Is there similar support for managing the Hard Disk Drive and the RAM (spinning down the HDD, lowering RAM frequency or anything that might result...

Writing data chunks while processing - is there a convergence value due to hardware constraints ?

Hi, I'm processing data from a harddisk from one large file (processing is fast and not a lot of overhead) and then have to write the results back (hundreds of thousands of files). I started writing the results straight away in files, one at a time, which was the slowest option. I figured it gets a lot faster if I build a vector of a c...

How to read individual sectors/clusters using DeviceIoControl() in Windows?

I dropped my laptop while Windows was preparing to hibernate and as a result, I got a head crash on the hard drive. (Teaches me to get a hard drive and/or laptop with a freefall sensor next time around.) Anyway, running SpinRite to try to recover the data has resulted in all the spare sectors on the disk to all be all used up for all the...

Linux: Hard disk direct access (without any FS) from C program

Hello all, this is my first post here. I want to access the whole hard disk directly from a C program. There's no FS on it and never's gonna be one. I just want to open /dev/sda (for example) and do I/O at the block/sector level of the disk. I'm planning to write some programs for learning C programming in the Linux environment (...

Is there a muti index container for the harddisk storage rather than memory?

I need a muti index container based on red-black trees (something like boost::multi_index::multi_index_container) for the case of the harddisk storage. All data must be store on hard disk rather than in memory. Is there an open source container such that described conditions hold? Note. I use C++. ...

Is reading from remote networked memory mapped file or device block faster than reading from Local 7200rpm HDDs?

Or rather how does remote RAM compare against local Disk access? If the answer is "it depends", what are the conditions? Data access patterns, ratio of read-to-writes, distance etc. Finally, what if the local disks are NetApp filers? Thanks. ...

How do I access hard drive from boot disk?

A computer, which the hard drive is configured as raid(not sure about the raid number or master or slave), has a corrupt file called stpd.sys which doesn't let me start up windows in normal mode or safe mode.

Does it make sense to optimize queries for less i/o pressure?

I have a read only database (product) that recides on its own Sql Server 2008. I already optimized queries by looking at most expensive queries in activity monitor - report. I ordered the report by CPU-cost. I now have something like 50 queries/second and no query is longer than 300ms. CPU-Time is ok (30%) and Memory is only used by 20...
