Here's a device more suited to TBolt than a portable disk like the LaCie...
I know, and I've linked it on a number of occasions already, as I also see it as the way for storage to truly utilize the TB interconnect. The LaCie is a bit of an odd-ball (fast, but 2x SSD's are limited in both capacity and what you can do with them; i.e. can't run but RAID 1 once it's been reconfigured <assuming it can> for a redundant means of storage). So I see it as more of a means for things like OS and audio library storage for example (need fast random access reads, and this assumes the striping doesn't actually slow it down in this regard, as sometimes does).
Most enterprise customers are moving away from host based storage solutions and more towards network based storage solutions (NAS over existing TCP/IP infrastructure or dedicated SANs). Host based storage is a nightmare to manage. TB being a host based technology pretty much guarantees it's non-acceptance into enterprise solutions.
TB's not aimed at the enterprise market in it's current form though. It's a cross between consumers (convenience, but cost information suggests it's going to be too expensive for this group), and a niche of independent/SMB professionals, such as audio or video editing done on a laptop (i.e. location shooting of a commercial or movie types of situations where hauling the entire desktop and accoutrement's around are a massive hassle). So we're talking about DAS here, not NAS or SAN.
Before it was released as TB, Light Peak had (still does if they get what they originally proposed out) potential for the enterprise market (i.e. cheap, fast optical interconnect definitely gets attention in this market, as current optical tech is expensive). Granted, it wasn't initially stated it would be usable as a networking interconnect, but the potential was there, and may still be if they've not totally given up on it. But if they can't get the optical circuits in at the low cost it initially promised (they may be trying to wait for graphene based optical modulators to accomplish this), it may not take off there either, as FC can already fit the bill as a usable optical networking interconnect that costs an arm + leg.
Small/medium business ? Yeah, I guess. Low server count to manage, so the problems of host based storages are minimized (though always there...), but then again, NAS is so cheap these days that even these businesses can get all the advantages of network based storage (pooling and consolidation of storage resources) without added costs.
NAS may be cheap to implement, but it's also slow (presumes the budget's not there for 10G Ethernet; but if it is, the requirements probably will lean towards SAN as the right fit anyway).
But, few enterprise customers are using Apples in their data centers.
True, and despite the argument that Macs are cheaper in terms of IT costs, there's other considerations to be taken into account as well (support is a big one IMO, as they really do need things like same day hardware support while it's under warranty). Apple falls flat on their faces on this one.
