![]() ![]() I've only used the GlobalSAN iSCSI initiator and it seems to work fine. I think it's a shame, but Mac users must buy an iSCSI initiator from either: In contrast, Windows 7 does have a very good iSCSI initiator. Mac OS X does not natively support iSCSI, it has no native iSCSI initiator (client). Just disconnect it from your NAS and hook it up to your Mac.īecause hard drives attached through iSCSI are seen as normal storage, you can also encrypt them with the Apple build-int whole-drive (or whole-partition) encryption. In case of an emergency - when your boot drive dies - you can boot from this external hard drive. I would just hook up an external USB drive to my NAS and export it through iSCSI. This trick allows you to create bootable Super Duper clones of your boot drive through the network. iSCSI is totally transparent from the perspective of the operating system. Your computer does not see the difference between an external USB hard drive and a hard drive exported through your NAS to your computer. ![]() This is very cool, because you can export entire hard drives through the network to your computer. Since iSCSI uses your Gigabit network as a transport, you can achieve transfer speeds of around ~110 MB/s easily, which should suit most needs*. Most NAS devices support iSCSI and allow you to carve out some local NAS storage and present it to your computer through the network as if it was just local storage. It's basically a storage protocol tunneled through your home LAN network instead of a USB / Firewire or Thunderbolt cable. Now there is a cool technology called iSCSI. Those NAS devices pretend to be Time Capsules, but there's always the risk that Apple breaks compatibility with a future update.įrom my experience, Time Machine backups are only 100% reliable with local attached storage - like external hard drives. The main problem being the reliability of network-based Time Machine backups. I'd like to move away all my storage from my living room (or home office) and put it in another room or even closet.Ī NAS may help with that but a NAS does not solve all problems. External hard drives make noise and create clutter. There are no current development plans to provide support for the ARM architecture or newer macOS versions.In the past, as a Mac user, I've used separate external drives for Time Machine backups and Super Duper clones but I'm not happy with that. ![]() Since globalSAN relies on support for kernel extensions, the initiator is not compatible with Apple Silicon (ARM) systems. To our knowledge, Recovery Mode intervention is required for any iSCSI initiator using kernel extensions in macOS 11. To use globalSAN on an Intel-based (not ARM/Silicon) Mac running Big Sur, it is necessary to instruct the operating system to allow a custom kernel extension, and this control is only exposed in Recovery Mode. As of macOS 11.5.1, disabling SIP is no longer required for installation.īecause of the latest changes to the macOS security model, globalSAN is not compatible with the default macOS 11 settings. Note: The following only applies to early releases of Big Sur. The initiator is not compatible with macOS 13 Ventura or later. There are no known issues with macOS 12 Monterey (Intel-only). The iSCSI protocol requires access to low level system frameworks, so the implications for globalSAN are even greater. This has massive implications for many existing applications, and we'd definitely recommend checking macOS compatibility for all critical software prior to updating any Mac system s. The release of macOS 11 marks Apple's first major version upgrade since OS X (10) was launched in 2001 (the changes in this operating system are significant enough that it warrants a new major version number). GlobalSAN is EOL and no longer available for sale. Please click here if you need to retrieve an existing license. ![]()
