Lenovo ThinkSystem SR635 2.5" NVMe Gen4 2-Bay Rear Drive Kit v2
The Lenovo ThinkSystem SR635 2.5" NVMe Gen4 2-Bay Rear Drive Kit v2 is a purpose-built expansion solution designed to maximize performance and efficiency in a compact server footprint. This rear-drive kit enables two hot-swappable 2.5-inch NVMe drives to be mounted at the back of the ThinkSystem SR635 family, freeing front bays for maximum I/O flexibility and improved airflow. Built for data-intensive workloads, this kit helps accelerate databases, virtualization, big data analytics, and high-velocity caching apps by delivering the speed of NVMe Gen4 with the reliability and manageability Lenovo is known for. Whether you’re expanding storage for a growing virtualization environment, implementing a high-performance database, or adding fast scratch space for in-memory workloads, this rear drive kit is designed to integrate seamlessly with your SR635 server and existing backplane, ensuring a clean, organized configuration with minimal downtime.
- Dual 2.5-inch NVMe Gen4 drive bays in a compact rear-facing kit provide high-bandwidth storage expansion for demanding workloads. By leveraging NVMe Gen4, you benefit from lower latency and higher throughput compared to traditional SAS/SATA options, making this kit ideal for databases, VDI, and large-scale caching applications.
- Rear-mounted design for optimized airflow and cabling This kit moves storage to the back of the chassis, freeing front-panel space and promoting improved cooling efficiency. The result is a cleaner interior with reduced cable clutter, which can help sustain performance under heavier I/O loads.
- Tool-free drive carriers and streamlined installation The enclosure ships with user-friendly, tool-free carriers that simplify drive installation and replacement. This translates to faster maintenance windows, reduced downtime, and easier upgrades for administrators managing growing storage needs.
- Plug-and-play compatibility with Lenovo ThinkSystem SR635 Designed to integrate with the SR635 family, this rear drive kit aligns with Lenovo’s backplane ecosystem to ensure reliable operation and consistent firmware behavior. It’s an excellent option for organizations standardizing on ThinkSystem hardware and seeking a scalable storage upgrade without complex reconfiguration.
- Reliable, enterprise-grade build with Lenovo support Expect durable construction and Lenovo’s support ecosystem, including warranty coverage and access to Lenovo’s service network. This kit is built to endure the rigors of data-center environments and to support ongoing maintenance with minimal disruption to operations.

This company makes great toys for pitts!!
Color: Blue/Medium, Size: Blue, Color: Blue/Medium, Size: Blue
Our pitt LOVES this toy. The rubber is reeeaally tough. It’s well designed because it’s a slippery surface. You can tell from the video there’s a lot of squeaking from him trying to get a good grip. He found a pretty good spot to hook his upper teeth into the crevasse, but his bottom teeth kept slipping.
As a side note, I wouldn’t leave any toy home alone with him that’s about 3 inches or smaller because dogs can choke on it, but that doesn’t make this any toy or company any less amazing. For toys I would leave home with a power chewer, take a look at that 4inch red ball made by this same company. He hasn’t made a dent in that thing and you can put treats in it. :)

Takes a beating - looks like new!
Color: Blue/Medium, Size: Blue
EDITED AGAIN, 12/28/22:
My boy still has his original blue one of these and the yellow one from way back. He's received a couple more over the years which he's managed to sneak out of the house and lose - evidently neighbor dogs or perhaps foxes, etc love them, too, and carry them off?! At any rate, he'd managed to get himself back to his original two, so I bought him a late Christmas present of a new yellow bone. He just opened the package (with help, of course - he's smart, but lacks the necessary opposing thumbs to do it on his own) and he was ecstatic! He reached into the mailing envelope, grabbed it, gave it a couple of triumphant tosses then ran for his bed, pulled a blanket in, and has been chewing, fighting with, burying in the blanket and "discovering" it for about a half hour now! I don't know what the attraction is, but he still loves these things and they're still lasting! The only other toys that have lasted more than a day are Nylabones (because he won't even look at them, let alone touch them) and a set of interlocked skinny rubber rings that he's not at all interested in, but if I ask about them, he'll move them around the room for a couple of days to make me feel better! LOL
EDITED TO ADD 2022:
Here I am, back 5 1/2 years later to say my dog STILL has this bone and makes use of it a couple of times a week. And he still loves it and sleeps with it. He has gone through a couple of the smaller version (yellow instead of blue) over this time frame because those get constant use. But that’s amazing in itself!! These are still the only toy I would call indestructible.
Great toy! I have a dachshund who destroys toys in record time. I can hear the amused chuckles now, but anyone who has seen him in action (including rottie, pit bull and Doberman owners) is in awe. He is very methodical and relentless - the mad genius of dog toy torture! Small and quiet but utterly ruthless.
Anyway...my boy has been working on this since the beginning of October and the thing looks like new! I think you can see one tooth mark, otherwise it looks untouched! This is a dog who can reduce Kongs and other rubber toys to a pile of chunks in minutes.
But he also LOVES it - carries it around, brings it into his bed at night to sleep, and when his doxie brother (who is far too dignified to do dog toys) doesn't feel well, it is offered up as a "feel better" snuggly...for about 2 minutes. But it's the thought that counts, right?
I don't know what makes this so attractive to my mini-Jaws and so long-lasting, but it works!

HEAVEY Duty!
Color: Blue/Medium, Size: Blue
Almost not destructible! My dogs chew through 99% of the toys we purchase, but never this one! The medium size is good for our Doberman with jaws of steel!
