Components Used. The information in this document is based on these software and hardware versions Cisco IOS Release 1. T or later. Cisco IOS XE Release 1. S 3. 7. 0 or later. The information in this document was created from devices in a lab environment. All of the devices used in this document started with a cleared default configuration. If your network is live, make sure that you understand the potential impact of any command. Background Information. When enabled, the router captures the packets sent and received. The packets are stored within a buffer in DRAM and are thus not persistent through a reload. Once the data is captured, it can be examined in a summary or detailed view on the router. In addition, the data can be exported as a packet capture PCAP file to allow for further examination. The tool is configured in exec mode and is considered a temporary assistance tool. As a result, the tool configuration is not stored within the router configuration and will not remain in place after a system reload. The Packet Capture Config Generator and Analyzer tool is available for Cisco Customers to aid in the configuration, capture, and extraction of packet captures. Cisco IOS Configuration Example. Basic EPC Configuration. Define a capture buffer, which is a temporary buffer that the captured packets are stored within. There are various options that can be selected when the buffer is defined such as size, maxium packet size, and circularlinear monitor capture buffer BUF size 2. A filter can also be applied to limit the capture to desired traffic.

Temp SSD solutions. Q1 Is there a utilitytool or operation guide for SMART command A1 A SMART attribute description for Stor. Fly drives is available. Customers can issue standard SMART commands to get SMART data. Q2 What is Virtiums over provisioning percentage A2 SSD manufacturers implement various methods to improve performance, and one of these is to allocate more free space, a process known as over provisioning. Virtiums over provisioning percentage for standard part numbers is typically 7 of the capacity. For custom part numbers, this value can be set to any value that customers need. Q3 What is the spare capacity of an overprovisioned drive resulting in reduced user capacity used for A3 The over provisioned capacity that nets 2. GB, for example, is primarily used for flash management to help reduce write amplification and improve wear leveling efficiency as well as increase the number of spare blocks for badworn block replacement resulting in improved drive endurance. Q4 Can a SATA 6. Gb drive be configured for 3. Gb access only i. Gb3. Gb be disabled A4 Fixed 3. Gb mode can be supported in a custom configuration under custom part. Q5 How does Stor. Fly SATA negotiate the SATA link speed A5 During the power up sequence, the host will issue Identify Drive, Mode Sense, and Read commands. The Stor. Fly device will respond with Identify Device data specifically word 7. Serial ATA capabilities as shown in the Stor. Fly datasheet. The drive will negotiate from its highest SATA link mode SATA III6. Gb first and then work down to lower modes until a successful negotiation is established. Q6 Do Stor. Fly drives support TRIM A6 All Stor. Fly drives support TRIM. Q7 How do Stor. Fly drives maintain steady performance over the life of the drive Does Virtium precondition its drives A7 All Virtium drives are preconditioned programerase drive 2 times during test so documented performance numbers are based on steady state performance meaning that no appreciable performance degradation should occur over life of drive. If a customer wishes to see the same steady state performance in their application then they should also precondition the drives before deploying. Otherwise, the TRIM feature in the drive firmware helps to minimize performance degradation, although there may be some small latency effects at certain times when the drive is conducting flash management activities including TRIM, garbage collection, mapping table updates, etc. This is true of all SSDs from any vendor. Q8 Does Virtium fully test each drive before shipping it outA8 Yes, Virtiums production test covers a full drive write on every drive. This means we write and verify every LBA of each drive before we ship out. We also test at industrial temperatures for I temp rated configurations. Q9 When do Virtium drives become read only A9 Drives become read only when spare 0, regardless of life remaining. Q1. 0 Do Virtium drives stop working when the SMART attribute life remaining is zero A1. The drive will still run when life remaining 0 and will continue to run for a while. However, it is not recommend to keep running when life 0 as it can fail any time after that. Q1. 1 Could you clarify the difference between SMART attribute 0x. A1 and 0x. F9 A1. SMART attribute 0x. A1 1. 61 Number of remaining spare blocks. SMART attribute 0x. F9 2. 49 Percentage of remaining spare blocksIf the initial spare block count is 1. If the initial spare block count is 1. Additionally, users can benefit from Virtiums vt. View software, which provides a time based estimate of the remaining spare blocks versus a percentage. Q1. 2 What is the NAND endurance of MLC, i. MLC, and SLC and how do I read itA1. CE class MLC, 1. X with 3 year warranty. Example 2. 40 GB, 6. TBW 2. 3 DWPD 3 yearsXE class i. MLC, offers 7. X endurance compared to CE with 5 year warrantyExample 2. GB, 4. 20. 7 TBW 9. DWPD 5 yearsPE class SLC, offers 3. X endurance compared to CE with 5 year warranty. Example 2. 56 GB, 2. TBW 5. 1 DWPD 5 yearsndurance baseline one entire drive write per day for the entire warranty period. Results are higherlower based on various readwrite workloads. Q1. 3 What is the difference between M. B, M, and BM A1. Currently an M. SSD has either one of three key types B, M, or BM. B keying pins 1. PCI Express SSDs up to 2x lanes of bandwidth. M keying pins 5. PCI Express SSDs with up to 4x lanes of bandwidth. Note Even with 2x lanes of bandwidth, a B keyed M. SSD still gives 1. Gbits performance, whereas the 4x lanes on M give up to 2. Gbits. 3 M. 2 SSDs with BM keying maximize compatibility in both slots, and will operate with 2x lanes of bandwidth. See image below. Q1. What is Virtiums secure erase and how does it workA1. The user issues a SATA command to implement a secure erase, which will physically erase all user data blocks including spare areas. Virtiums secure erase is persistent over power cycles. If the drive loses power during the erase, it will automatically resume erasing upon subsequent power cycles. Q1. 5 What is AHCI A1. AHCI is a technical standard that specifies the operation of Serial ATA SATA host bus adapters in a non implementation specific manner. AHCI stands for Advanced Host Controller Interface. Average Cost To Replace Broken Window Pane. AHCI mode must be enabled to use Native Command Queuing NCQ or Hot Plugging aka Hot Swapping functionality as well as Power Management in SATA storage devices. Q1. 6 Why does Virtium use tantalum capacitors in our designs A1. We use tantalum capacitors as a part of our vt. Guard power down protection technology for Stor. Fly and Tuff. Drive SSDs. Tantalum capacitors have the best energy density for small form factor SSDs like e. USB, CF, M. 2, m. SATA, Slim SATA, and CFast. Tantalum capacitors also offer a wide operating temperature range making them ideal for use in industrial environments. Q1. What is MIL STD 8. Which Virtium products are compliant A1. MIL STD 8. US military standard that specifies a set of environmental conditions i. All Virtium Stor. Fly SSDs support the MIL STD 8. F environmental standard. Tests conducted include EMI, temperature, operatingnon operating shock, operatingnon operating vibration, and altitude testing. Q1. 9 What is garbage collection A1. Flash memory is grouped into pages, which is the smallest amount of flash that can be written. Pages are collected into blocks, which is the smallest amount of flash that can be erased. Flash memory must be erased before it can be programmed. Due to these two different sizes, during operation, pages are rewritten to other pages and the older pages are left behind in the block. Garbage collection is the process where the controller reclaims blocks by moving all valid pages from a block so that it can be erased and used again to store new data. This combining of the still valid blocks into a new block will increase writes to the flash beyond what the user is requesting, also known as write amplification. This is analogous to HDD defragmentation where all the files are realigned to improve performance. In SSDs, this realigning of data is creating space for new data to be stored in the flash. Q2. 0 What is write amplification WA or write amplification factor WAF A2. Write amplification WA is defined as the number of writes to the flash divided by the number of writes by the user.
