HyperThreading Bug in Intel Skylake and Kaby Lake CPUs

Bug

A warning appeared on the Debian Linux mailing list over the weekend that there is a bug in the hyperthreading logic in some of Intel’s latest processors codenamed Skylake and Kaby Lake. The good news for data center operators is that the E5 and E7 Xeons that populate the world’s 2 socket and larger servers are still using and older …

vSAN 6.6 Matures with Encryption, Site Data Protection

VMware’s done an impressive job of bringing the Internet development cycle of incremental releases twice a year and applying it to the traditionally much stodgier world of enterprise storage where customers are used to waiting three to five years for the new features that come with an array’s generational update. The latest 6.6 release adds over 20 new features, and …

AMD Attempts Epyc Return to the Data Center

Epyc

AMD this week finally announced their new Epyc line of server processors and for the first time in a long time, it appears AMD has processors that can actually compete with Intel’s data center world dominating Xeons. While most of the attention so far has been on the top of the line 32 core model if Epyc has an epic …

Visiting Intel with SFD 12

Lotus Lightnes

Intel is always an interesting stop on the Storage Field Day whirlwind tour of Silicon Valley. During SFD8 we learned about how Intel tested their SSDs for radiation performance just up the mountain from DeepStorage Labs at Los Alamos and gave my podcasting partner Ray Lucchesi the nickname Cosmic Ray. With Intel at the heart of new technologies like NVMe …

Unifying Sync ‘n Share

Like most people nowadays I use sync ‘n share services as a central part of my work process. I even wrote a blog post describing the process I used to synchronize my supplemental dictionaries between the various PCs I use on a regular basis. While SnS is a great solution to my personal file problems, DeepStorage Labs still needs more …

New In The Lab: 25/40/100Gbps Networking

For the past few years, Ethernet has come in four speeds: 1, 10, 40 and 100Gbps. While the cost of 10Gbps Ethernet has fallen to under $500 a port, the next step up 40Gbps has remained four times as expensive as 10gbps and therefore been relegated to inter-switch links and the like. This year Santa brought us 25Gbps Ethernet which …

Scality’s S3 Server Brings Object Storage to The Masses

Lego Docker Logo

And DeepStorage Labs As recently as two or three years ago I would only recommend object storage to users who had requirements exceeding the capabilities of an enterprise NAS file system. The additional effort of writing applications to use new, and different, APIs wasn’t worth it for less than hundreds of terabytes of data. Times have changed. Backup, archiving, and …

Chatsworth’s Clik-Nut Perfects the Cage Nut

I thought I had said all there was to say about the prosaic little cage nut in my 2000 word blog post in 2014. I even did a 1500 word follow up on alternatives like Rackstuds. I was therefore pleasantly surprised when I got an email from the folks at Chatsworth Products telling me that the tales of my travails with …

Why Primary Deduplication Is A Different Animal From Backup Dedupe

A decade ago, storage admins took a chance on purpose-built backup appliances (PBBAs) (Insert link to Take a chance on me) and the magical technology that made them cost effective for data deduplication. It took a few years to convince the tape huggers (except maybe Jon Toigo) but the Society of Steely-Eyed Storage Professionals has acknowledged that deduplication is safe …

On Calling Out and Being Called Out

It’s interesting how companies develop corporate personalities that extend not just to official communications but even to employees’ personal blogs. A few years ago, this was most apparent at NetApp and EMC. Today, the most visible example is how folks at Nutanix seem to take even the most tangential reference or minimal criticism as direct attacks that must be responded …
