LSI WarpDrive SLP-300 Review
LSI WarpDrive SLP-300 is a solution for enterprise-class SSDs, which operates the PCIe x8 expansion slot in a server or desktop. With features like 300 GB SLC flash memory, six SF-1500 controllers, and a 533Mhz SATA6 LSI RAID controller link all elements, this card promises extremely high transfer speeds, with extremely low latency, and priced extremely high high. LSI promises up to 1,400 MB / s sustained throughput, 0.5 microsecond-looking, 240,000 4K read IOPS, and 200,000 IOPS 4K for the low, low MSRP of $ 11,500 ($ 7,700 street), which places resolutely out of reach of most power users.For its target audience well, it's theft.
The main objective of the WarpDrive is IO intensive applications server or workstation, as high-traffic Web sites, databases, and encoding video, which require high throughput and low latency more important. large websites serving thousands of pages per second requires a huge amount of IOPS, like database subsites. Although the initial flow rate are important for these operations is the low latency really makes the difference.If a web page takes 300ms to be retrieved from a storage situation, then it is at least a period of 300 ms for the viewer page. In addition, visits the page can begin to accumulate, causing disk access slower and slower. LSI claims (using the TCO tool) if you compare Warpdrive vs. standard storage solution consisting of 73 GB 15K Drives 2.5 "drive, they feel the WarpDrive would save more than $ 15,200. Most people do not realize that modern servers are limited by their storage processor, RAM, or bandwidth.Database IO in particular are hungry, because whenever they are available, they update on disk. Most hard drive based RAID 0 solutions are not an option for commercial databases because of concerns of resilience. RAID 1 is also impossible for a single disk can not generally provide the performance needed for a database widely used. RAID 5, RAID 6 and RAID 10 are achievable, but require many expensive hard drives, a RAID controller appropriate, and physical space in the server for them. The LSI takes everything and sticks everything on one card half-height PCI Express.Consider a use case of real life involving the server that supplies a wide range of open source projects, including Linux and NSLU2 internal WebOS. It receives an average of 10 shots per second MySQL, which may not seem like much, but what comes out to about 26 million disk write only one month from MySQL. That in turn generates an average of 50 E / S / her second and probably more importantly, an average of 200 ms of IO wait. It's almost the limit of the disk (s), it is now, which is a 10k 2.5 "drive 300 GB SAS, but as we have seen, the INS can handle 20 times the IO / s without breaking a sweat .And that includes the sustainability of SLC NAND flash.
Chase Continental One Pass Credit Card Offer Details
For decades, an airline without an affiliated credit card has been like an airplane without wings. While every carrier offers their own branded card, some cards deliver more value to the cardholder than others. The Chase Continental OnePass Plus card is one such card that brings a lot of valuable perks to the table. It offers up thousands of free miles to new cardmembers just like every other airline card, but really stands out from the crowd by offering free checked bags to cardholders and their travel companions.
Key Features of the Chase Continental OnePass Credit CardThe benefits of the Chase Continental OnePass Plus credit card begin with a competitive sign up bonus of 25,000 miles after your first purchase. They then add an additional 5,000 bonus miles when you add an authorized user to your account within two months of opening it. Furthermore, they give you a $50 statement credit with your first purchase. Like almost all airline credit cards , they offer a mile per dollar spent on most purchases and two miles per dollar spent on Continental airlines.
When it comes time to redeem your miles you have some pretty good choices. As a member of the Star Alliance, Continental OnePass miles can be used for award travel on airlines such as US Airways, Lufthansa, Swiss, Thai, and of course, merger partner United. Continental OnePass miles can also be redeemed for hotel and car rental awards. My advice is to never redeem miles for a rental car award. It is a little known fact that only paid rentals are covered by the insurance your credit card provides. The cost of buying insurance from the rental agency is almost as much as the price of a discount rental anyways, negating the value of the reward.
The standard Continental One Pass credit card comes with a $95 annual fee that is waived the first year. The elite OnePass Presidential Plus credit card carries a $395 and comes with added benefits, including full Presidents Club membership and no foreign transaction fee , but this card is best left to the highest spending frequent flyers.
Free Checked BagsOne of the ways that Continental customers can benefit from this card more than most other airline credit cards is by utilizing the fee waiver for checked bags. Holders of the Chase OnePass Plus card and their companions pay nothing to check their first bag, a savings of up to $50 per person on a roundtrip flight. This benefit extends to up to eight other passengers traveling on the same itinerary. This could be of substantial value for a family taking a ski trip or an extended vacation that requires luggage. A family of four can save $200 in bag fees on one trip, more than enough to earn back the annual fee.
