How to install Lenovo PM1645a

Installing the PM1645a is straightforward in compatible ThinkSystem systems and other enterprise SAS environments that support a 2.5-inch drive with a standard carrier. Follow these steps to ensure a smooth deployment and optimal performance:

  • Prepare the system: Verify that your ThinkSystem server or storage array supports a 2.5-inch SAS SSD and that the server firmware and RAID controller firmware are up to date. Review vendor guidelines for hot-swapping in your chassis and ensure maintenance procedures are followed.
  • Power or prepare for hot-swap: If your platform supports hot-swapping, you can replace or add drives without powering down the system. If not, power down according to your platform's instructions before proceeding.
  • Open the drive bay: Access an available 2.5-inch drive bay in the chassis or backplane. Release the bay latch or remove mounting screws as required by your enclosure.
  • Insert the PM1645a with its carrier: Align the PM1645a with the 2.5" carrier and slide it into the bay until the connectors engage with the backplane. Ensure the drive is seated securely and the carrier is locked in place.
  • Connect and verify: If required, confirm SAS backplane connectivity to the RAID controller. Power on (or resume) the system and use the server management interface to verify that the PM1645a is detected.
  • Phase in firmware and configure: If a newer firmware version is available, update the PM1645a through Lenovo or the RAID controller vendor's update utility. In the operating system or storage management software, initialize the drive, configure it into the appropriate RAID group or storage pool, and format as needed for your workload.
  • Monitor and optimize: After installation, monitor drive health, throughput, and endurance through ThinkSystem XClarity Administrator or your preferred management tool. Schedule regular health checks and firmware updates to maintain performance and reliability.

Nice mask! Caviar
Scent: PDRN, Size: 4 Count (Pack of 1), Scent: PDRN, Size: 4 Count (Pack of 1)
The first 3 pictures were taken after the first hour and a half. The second 3 pictures were taken at 2 hours. The mask had a hard time dissolving underneath my eyes and around my chin area mostly but everywhere else it hardened within the first hour or so. I will try to wear it for longer than 2 hours next time. To see if that changes, but my skin feels really nice right now. It's a little sticky, but it looks healthy and has a nice glow. Application is easy. I love that its separated into 2 parts. Doesn't fit well around the nose between the eyes and doesn't cover my entire face but its a great mask. I tried the caviar one this time. I have the collagen ones as well but these have better reviews. They seem to work effectively, for a nice glow and self pamper session.

My Favorite Mask
Scent: Collagen, Size: 4 Count (Pack of 1)
I’ve been really impressed with this Bio-Collagen hydrogel mask! It feels incredibly cooling and soothing on the skin, especially after a long day. The overnight wear is a huge plus—you wake up with your skin feeling noticeably more hydrated, plump, and smooth. It doesn’t feel heavy or sticky, and it stays in place better than most sheet masks. After a few uses, I’ve noticed my skin looks more refreshed and even, and my pores appear a bit more minimized. It’s a great option when your skin needs a little extra boost or before an event when you want that “glow.”

Love ❤️ this product! 100% recommend!
Scent: Collagen, Size: 16 Count (Pack of 1)
My initial encounter with these was until TikTok but I ordered them from Amazon for myself and my daughter for convenience and Prime shipping. There were two choices I think the one is a four-pack and the one I got is a 16 pack. The 16 pack will last you 4 months if you're doing it once a week as instructed. I open the top and two sides when I'm doing it just to have accessibility and to be able to use the remnants liquid in the pack after I'm done applying the facial part I put the liquid in the pack on my neck and chest. They are a little slippery when you take them out. I watched a video on how to apply it and did the bottom part first and then the top part sometimes I have to snip the top part near the nose to get it to fit properly but you don't have to in general. There are three pieces that are left over the two eye pieces and the lip piece. You can put them below your eyes or above your eyes on your brows and then put the mask over them which is what I do. Or you can put them under your eyes and put the mask over them but I find it doesn't absorb all the way in that location due to the double thickness I guess. The lip one you can put over your lip or put it on vertically over your throat where the skin can get a little saggy. Once you have it on it's best to sit back and relax for 30 minutes or so at about a 45° angle so it doesn't slip off. After about 10 to 15 minutes it doesn't slip around as much and after 30 it's obviously started absorbing and tends to stay pretty well. I haven't noticed any staining on the pillows or anything like that from it and by morning actually by 4 hours later it's completely absorbed and all you have left on your faces the plastic that it was attached to. You just pull that off and throw it away. It's white when you put it on and it's clear when it absorbs. I definitely noticed an improvement in my skin quality and the collagen sinks in easily and less about a week. I am a redhead with delicate skin and I haven't had any reaction to this product at all I know that other masks have caused problems for friends but I've used this one for over a year now and I love it. My daughter and I both use it weekly and they're easy to take with you if you're traveling great way to pamper your skin after a day outside on the beach. The price is reasonable for what it is and what it does. I've gotten several compliments on my skin and I'm over 60 so that saying something for the results! All in all this is a very good product, it doesn't smell and doesn't seem to have any impurities like some others. My skin isn't irritated by it and looks great afterwards. If you're wondering if it washes off once it's soaked in you can wash your face all you want but you're just going to have beautiful glowing cheeks. I wouldn't hesitate to recommend this or give it as a gift!

Great Lotion for the price
Size: 32 Ounce (Pack of 1)
I recently picked up the Queen Helene Cocoa Butter Hand & Body Lotion, and I have to say, it’s quickly become a staple in my skincare routine. The first thing I noticed was the rich, creamy texture. It glides on smoothly and doesn’t leave that greasy feeling that some lotions do, which is a huge plus for me. The cocoa butter scent is delightful but not overwhelming. It reminds me of a warm, cozy day, and it lingers just enough to be pleasant without being too much. I usually apply it after my showers, and my skin feels so hydrated and soft for hours afterward. I also appreciate that it comes in a big 32 oz size. I feel like I’m getting good value for my money, and I don’t have to worry about running out anytime soon. Plus, it’s versatile—perfect for both my hands and body. Overall, I’ve enjoyed using this lotion, and it’s definitely helped to keep my skin feeling moisturized, especially as the weather gets colder. If you’re looking for a budget-friendly option that really delivers on hydration and has a lovely scent, I’d recommend giving this one a try!

Queen Helene Cocoa Butter Hand and Body Lotion
Size: 32 Ounce (Pack of 1), Size: 32 Ounce (Pack of 1)
As someone who typically shies away from using lotion due to its heavy and greasy feel, I was initially hesitant to try the Queen Helene Cocoa Butter Hand and Body Lotion. However, after ordering a large bottle for both my husband and me, I can confidently say that I am pleasantly surprised by how much I love it. One of the first things that struck me about this lotion is its delightful scent. With every application, I feel like I've been transported to a serene beach setting, enveloped in the comforting aroma of cocoa butter. It adds a touch of luxury to my skincare routine and leaves me feeling refreshed and rejuvenated. What truly sets this lotion apart for me is its lightweight texture. Unlike other lotions I've tried in the past, this one absorbs quickly into the skin without leaving behind any greasy residue. I appreciate how effortlessly it spreads and how it doesn't weigh down my skin, allowing me to go about my day comfortably. Additionally, I've noticed that the Queen Helene Cocoa Butter Hand and Body Lotion provides ample hydration without feeling heavy or cloying. It leaves my skin feeling soft, smooth, and moisturized, without the need for constant reapplication throughout the day. I would highly recommend this lotion, especially for those with mature skin. Its lightweight, non-greasy formula makes it a joy to use, and the beach-like scent adds a delightful touch to the skincare experience. Overall, I'm thoroughly impressed with the Queen Helene Cocoa Butter Hand and Body Lotion and plan to continue incorporating it into my daily routine.
