Intel brought us out to their Folsom campus last week for some in-depth product briefings. Much of our briefing is still under embargo, but the portion that officially lifts this morning is the SSD DC P4800X:
MSRP for the 375GB model is estimated at $1520 ($4/GB), which is rather spendy, but given that the product has shown it can effectively displace RAM in servers, we should be comparing the cost/GB with DRAM and not NAND. It should also be noted this is also nearly half the cost/GB of the X25-M at its launch. Capacities will go all the way up to 1.5TB, and U.2 form factor versions are also on the way.
For those wanting a bit more technical info, the P4800X uses a 7-channel controller, with the 375GB model having 4 dies per channel (28 total). Overprovisioning does not do for Optane what it did for NAND flash, as XPoint can be rewritten at the byte level and does not need to be programmed in (KB) pages and erased in larger (MB) blocks. The only extra space on Optane SSDs is for ECC, firmware, and a small spare area to map out any failed cells.
Those with a keen eye (and calculator) might have noted that the early TBW values only put the P4800X at 30 DWPD for a 3-year period. At the event, Intel confirmed that they anticipate the P4800X to qualify at that same 30 DWPD for a 5-year period by the time volume shipment occurs.
If you’re a fan of digital video and music, you’ve likely heard the name “Plex” floating around. Plex (not to be confused with EVE Online’s in-game subscription commodity) is free media center software that lets users manage and stream a wide array of videos, audio files, and pictures to virtually any computer and a growing number of mobile devices and electronics. As a Plex user from the very beginning, I’ve seen the software change and evolve over the years into the versatile and powerful service it is today.
My goal with this article twofold. First, as an avid Plex user, I’d like to introduce the software to users have yet to hear about or try it. Second, for those already using or experimenting with Plex, I hope that I can provide some “best practices” when it comes to configuring your servers, managing your media, or just using the software in general.
Before we dive into the technical aspects of Plex, let’s look at a brief overview of the software’s history and the main components that comprise the Plex ecosystem today.
Although now widely supported on a range of platforms, Plex was born in early 2008 as an OS X fork of the Xbox Media Center project (XBMC). Lovingly named “OSXBMC” (get it?) by its creators, the software was initially a simple media player for Mac, with roughly the same capabilities as the XBMC project from which it was derived. (Note: XBMC changed its name to “Kodi” in August, although you’ll still find plenty of people referring to the software by its original name).
A few months into the project, the OSXBMC team decided to change the name to “Plex” and things really started to take off for the nascent media software. Unlike the XBMC/Kodi community, which focused its efforts primarily on the playback client, the Plex team decided to bifurcate the project with two distinct components: a dedicated media server and a dedicated playback client.
The dedicated media server made Plex unique among its media center peers. Once properly set up, it gave users with very little technical knowledge the ability to maintain a server that was capable of delivering their movies, TV shows, music, and pictures on demand throughout the house and, later, the world. We'll take a more detailed look at each of the Plex components next.
The “brains” behind the entire Plex ecosystem is Plex Media Server (PMS). This software, available for Windows, Linux, and OS X, manages your media database, metadata, and any necessary transcoding, which is one of its best features. Although far from error-free, the PMS encoding engine can convert virtually any video codec and container on the fly to a format requested by a client device. Want to play a high-bitrate 1080p MKV file with a 7.1 DTS-HD MA soundtrack on your Roku? No problem; Plex will seamlessly transcode that high quality source file to the proper format for Roku, as well as your iPad, or your Galaxy S5, and many other devices, all without having to store multiple copies of your video files.
