Co je hot-swap?

Ano, je to obecne oznaceni soucasti, ktere se daji vymenit za behu zarizeni. U enterprise zarizeni to byvaji disky, zdroje, ventilatory i cele servery (u blade center). Podminkou je, ze system je schopen zarizeni radne ukoncit (praci s nim), pak jej za behu lze vyjmout.

U PATA disku bych to zrovna neprovozoval, ale sata disky ve spojeni s vhodnym "suplikem" mohou, SCSI a SAS take ve spojeni s vhodnymi enclosery take umi.

U komplexnejsich reseni lze za jizdy prihazovat i pameti a procesory (OS400, i5 od IBM).

Ovsem u PATA skutecne nedoporucuji pouzivat hot swap, ac dle mnohych po odpojeni zarizeni v systemu neni problem. Mam odzkouseno, ze pripojit PATA nelze. PATA neni na hot swap urceno. U SATA na vyuziti hot swapu je potreba mit zaple ACHI a musi to byt podporovano chipsetem.

The standard interface for SATA controllers is Advanced Host Controller Interface (AHCI), which allows advanced features of SATA such as hot plug and Native Command Queuing (NCQ). If AHCI is not enabled by the motherboard and chipset, SATA controllers typically operate in "IDE emulation" mode which does not allow features of devices to be accessed that are not supported by the ATA/IDE standard. Windows device drivers that are labeled as SATA are usually running in IDE emulation mode unless they explicitly state that they are AHCI. While the drivers included with Windows XP do not support AHCI, AHCI has been implemented by proprietary device drivers.[1] Windows Vista and the current versions of Mac OS X and Linux [1] have native support for AHCI.

Unlike PATA, both SATA and eSATA are designed to support hot-swapping. However, this feature requires proper support at the host, device (drive), and operating-system level. In general, all SATA/devices (drives) support hot-swapping (due to the requirements on the device-side), but requisite support is less common on SATA host adapters.

eSATA drives are hot-pluggable, meaning that you can attach or remove an eSATA hard drive from a system without powering down the system or the drive.
